Introduction Google recently introduced a new chatbot called Meena, which has caught a lot of attention for its advanced design and features. Meena is aimed at creating chatbots that can interact with people more naturally, similar to how humans communicate. It's designed to have more open and natural conversations with users. It's based on a sophisticated architecture called Transformer seq2seq and has been trained on a massive amount of text data from social media conversations. Key Features of Meena One of the key aspects of Meena is its ability to understand context and respond accordingly. It's not limited to predefined rules or keywords like many other chatbots. Implementation Setting the Stage: Installing Necessary Packages Imagine preparing the stage for a grand show. Before we dive into the exciting world of creating a chatbot, we need to make sure we have all the right tools. In this case, we're using special software called TensorFlow to build our chatbot. So, we're quickly installing and updating the necessary packages to make sure everything runs smoothly. !pip install -q -U tensorflow-gpu==1.15.2 !pip install -q -U tensorflow-datasets==3.2.1 !pip install -q -U tensor2tensor import tensorflow as tf from tensor2tensor import models from tensor2tensor import problems from tensor2tensor.utils import hparams_lib from tensor2tensor.utils import registry from tensor2tensor.data_generators import text_problems import numpy as np import re import os tf.get_logger().propagate = False Downloading a Pretrained Model Now that we've got our tools ready, it's time to bring in the star of our show - our chatbot, Meena. But before we do that, we need to make sure it's dressed to impress. That means downloading a fancy, pre-trained model that will serve as the backbone of our chatbot's intelligence. model_name = "Italian_108M" !gdown https://drive.google.com/uc?id=1y0abt3nOKPo5DBfKx3b7A7pjm3GH3wi1 !unzip {model_name}.zip MODEL_DIR = model_name + '/' Setting the Parameters Let's start with MODEL = "evolved_transformer" and VOCAB_SIZE = 2**13. Here, we're setting up the model architecture and the size of the vocabulary. MODEL = "evolved_transformer" VOCAB_SIZE = 2**13 # sampling parameters CONVERSATION_TURNS = 3 SAMPLING_TEMPERATURE = 0.88 NUM_SAMPLES = 5 MAX_LCS_RATIO = 0.9 Enabling Eager Execution Now, moving on, tfe = tf.contrib.eager enables TensorFlow eager execution, which allows for immediate evaluation of operations, making debugging and interaction with the code easier. tfe = tf.contrib.eager tfe.enable_eager_execution() Modes = tf.estimator.ModeKeys Defining the Problem ChatBot inheriting from text_problems.Text2TextProblem, indicating that our chatbot's problem involves transforming one text into another. We're essentially setting up the problem structure for our chatbot within the Tensor2Tensor framework. @registry.register_problem class ChatBot(text_problems.Text2TextProblem): @property def approx_vocab_size(self): return VOCAB_SIZE Preprocessing and Postprocessing The preprocess_sentence function takes a sentence as input and performs several text preprocessing steps to make it suitable for the chatbot to understand. It converts the entire sentence to lowercase, adds spaces before punctuation marks, removes extra spaces, and non-alphanumeric characters. def preprocess_sentence(sentence): sentence = sentence.lower().strip() # creating a space between a word and the punctuation following it # eg: "he is a boy." => "he is a boy ." sentence = re.sub(r"([?.!,])", r" \1 ", sentence) sentence = sentence.replace("'", "' ") sentence = re.sub(r'[" "]+', " ", sentence) sentence = re.sub(r"[^a-zA-Z0-9?.!,àèìòùáéíóú']+", " ", sentence) sentence = sentence.strip() return sentence Now, let's move on to postprocess_sentence. This function takes a sentence generated by the chatbot and performs some post-processing to make it more readable. It removes trailing spaces and periods, and extra spaces before punctuation marks. def postprocess_sentence(sentence): # remove space before punctuation sentence = sentence.rstrip(" .") return re.sub(r"\s+(\W)", r"\1", sentence) Encoding and Decoding Encode and decode functions are responsible for converting text data into a format that the chatbot model can understand and vice versa. def encode(conversation, output_str=None): """Input str to features dict, ready for inference""" encoded_inputs = [] for conversation_turn in conversation: encoded_inputs += encoders["inputs"].encode(conversation_turn) + [2] encoded_inputs.pop() encoded_inputs += [1] if len(encoded_inputs) > hparams.max_length: encoded_inputs = encoded_inputs[-hparams.max_length:] batch_inputs = tf.reshape(encoded_inputs, [1, -1, 1]) # Make it 3D. return {"inputs": batch_inputs} def decode(integers): """List of ints to str""" integers = list(np.squeeze(integers)) if 1 in integers: integers = integers[:integers.index(1)] decoded = encoders["inputs"].decode(integers) return postprocess_sentence(decoded) Calculating LCS Ratio We have lcs_ratio, which calculates the Longest Common Subsequence ratio between the input conversation and a predicted response. This helps ensure that the generated response stays coherent with the context of the conversation. def lcs_ratio(context, predicted): m = len(context) n = len(predicted) L = [[None]*(n + 1) for i in range(m + 1)] for i in range(m + 1): for j in range(n + 1): if i == 0 or j == 0 : L[i][j] = 0 elif context[i-1] == predicted[j-1]: L[i][j] = L[i-1][j-1]+1 else: L[i][j] = max(L[i-1][j], L[i][j-1]) return L[m][n] / n Predicting The predict function takes a conversation as input. First, it preprocesses each turn of the conversation using the preprocess_sentence function. def predict(conversation): preprocessed = [preprocess_sentence(x) for x in conversation] encoded_inputs = encode(preprocessed) print("decoded input: " + decode(encoded_inputs["inputs"])) with tfe.restore_variables_on_create(ckpt_path): while True: output_candidates = [chatbot_model.infer(encoded_inputs, decode_length=1) for _ in range(NUM_SAMPLES)] output_candidates.sort(key = lambda x: -float(x["scores"])) for x in output_candidates: print(str(float(x["scores"])) + "\t" + decode(x["outputs"])) for candidate in output_candidates: decoded = decode(candidate["outputs"]) if lcs_ratio(" ".join(preprocessed), decoded) < MAX_LCS_RATIO: return decoded Managing the Conversation Loop This code snippet manages an ongoing conversation with a user by continuously prompting for input, storing the conversation history, generating responses using a chatbot model, and displaying the responses back to the user. conversation = [] while True: sentence = input("Input: ") conversation.append(sentence) while len(conversation) > CONVERSATION_TURNS: conversation.pop(0) response = predict(conversation) conversation.append(response) print(response) Output And that's the end! 🎉 We've finished our chatbot Introduction and Implementation Guide journey.

Introduction Chatbots are computer programs designed to simulate conversation with human users, typically through text or voice interfaces. In this tutorial, we will discuss a chatbot named DialogGPT. DialoGPT is a cutting-edge model used for generating responses in conversations involving multiple turns. When people evaluated the responses it produced, they found them to be similar in quality to responses from humans in one-on-one conversations. To train this model, it was fed with over 147 million conversations from Reddit discussion threads. These conversations happened between 2005 and 2017. Implementation Want to see how a chat with a cool AI model works using Python? Check out this implementation: Alright, before we set off, we need to make sure we have the right gear. In this case, we're going to need two key tools: AutoModelForCausalLM and AutoTokenizer from the transformers library, as well as torch. from transformers import AutoModelForCausalLM, AutoTokenizer import torch We will use a powerful AI model called DialoGPT to have a conversation. We start by loading the model and its tokenizer, which helps the AI understand what we're saying. tokenizer = AutoTokenizer.from_pretrained("microsoft/DialoGPT-medium") model = AutoModelForCausalLM.from_pretrained("microsoft/DialoGPT-medium") Now, we're going to chat for five lines. Each time, we'll do a few things. First, we'll take input from the user. Then, we'll encode that input using the tokenizer and convert it into a PyTorch tensor. # Let's chat for 5 lines for step in range(5):     # encode the new user input, add the eos_token and return a tensor in Pytorch     new_user_input_ids = tokenizer.encode(input(">> User:") + tokenizer.eos_token, return_tensors='pt') We'll combine the user's input with the history of our conversation so far. This history helps the model understand the context of the conversation. If it's not the first step, we'll add the new input to the existing conversation history. # append the new user input tokens to the chat history     bot_input_ids = torch.cat([chat_history_ids, new_user_input_ids], dim=-1) if step > 0 else new_user_input_ids It's time for the model to shine! We'll use it to generate a response based on the combined input and conversation history. We set a maximum length for the response to avoid overly long replies. # generated a response while limiting the total chat history to 1000 tokens,      chat_history_ids = model.generate(bot_input_ids, max_length=1000, pad_token_id=tokenizer.eos_token_id) Once we have the response, we'll decode it using the tokenizer to turn it back into human-readable text. Then, we'll print it out as the bot's reply. # pretty print last output tokens from bot     print("DialoGPT: {}".format(tokenizer.decode(chat_history_ids[:, bot_input_ids.shape[-1]:][0], skip_special_tokens=True))) Putting it All Together from transformers import AutoModelForCausalLM, AutoTokenizer import torch tokenizer = AutoTokenizer.from_pretrained("microsoft/DialoGPT-medium") model = AutoModelForCausalLM.from_pretrained("microsoft/DialoGPT-medium") # Let's chat for 5 lines for step in range(5): # encode the new user input, add the eos_token and return a tensor in Pytorch new_user_input_ids = tokenizer.encode(input(">> User:") + tokenizer.eos_token, return_tensors='pt') # append the new user input tokens to the chat history bot_input_ids = torch.cat([chat_history_ids, new_user_input_ids], dim=-1) if step > 0 else new_user_input_ids # generated a response while limiting the total chat history to 1000 tokens, chat_history_ids = model.generate(bot_input_ids, max_length=1000, pad_token_id=tokenizer.eos_token_id) # pretty print last ouput tokens from bot print("DialoGPT: {}".format(tokenizer.decode(chat_history_ids[:, bot_input_ids.shape[-1]:][0], skip_special_tokens=True))) Output Advantages Real-World Training Data: DIALOGPT has been trained on a massive dataset of real conversations from Reddit. This means it has been exposed to a wide range of topics and language styles commonly used by people online. Easy to Deploy and Extend: DIALOGPT is open-source and straightforward to implement. Users can fine-tune it for specific tasks or datasets relatively quickly, making it adaptable to different applications. Building Block for Applications: DIALOGPT serves as a foundational tool for developing various conversational applications and methodologies. Its flexibility allows researchers and developers to explore new possibilities in natural language processing. Future Focus on Toxic Output: The creators acknowledge the importance of addressing toxic or harmful content generated by models like DIALOGPT. They plan to focus on improving detection and control of such output, potentially using reinforcement learning techniques. Limitations and Risks Model Only Release: DIALOGPT is provided as a model without the implementation of the decoder. This means users need to do additional work to make it function fully. Offensive Output Potential: Despite efforts to remove offensive data during training, DIALOGPT still has the potential to generate offensive responses. This could be due to biases present in the original data, including historical biases regarding gender and other factors. Propensity for Unethical or Biased Responses: Responses generated by DIALOGPT might show a tendency to agree with unethical, biased, or offensive statements. This could include expressing agreement with ideas that are harmful or discriminatory. Lack of Human-Likeness Guarantee: While DIALOGPT is designed to mimic human conversation, it might not always generate responses that seem entirely human-like. Users might encounter responses that seem more artificial or robotic. Known Issues in State-of-the-Art Models: DIALOGPT shares common issues with other advanced conversation models, such as generating inappropriate or disagreeable content. These are challenges researchers are actively working to address. And there you have it! 🎉 We've reached the conclusion of our DialoGPT Introduction and Implementation Guide journey. We sincerely hope that this guide has provided you with valuable insights and practical knowledge.

Introduction Meta, formerly known as Facebook, has introduced a cutting-edge chatbot named BlenderBot 3 and has opened it to public interaction to gather feedback on its capabilities. Accessible through the web (currently limited to US residents), BlenderBot 3 boasts versatility in engaging in casual conversation as well as addressing queries akin to those posed to digital assistants, covering topics from healthy recipes to locating child-friendly amenities in urban areas. Advancements in Large Language Models This chatbot, a prototype, is the result of Meta's continued advancements in large language models (LLMs), building upon previous work with models like GPT-3. Utilizing vast datasets, BlenderBot mines text for statistical patterns to generate language. Despite their flexibility, LLMs are known to carry biases and sometimes provide inaccurate responses—a challenge Meta aims to tackle with BlenderBot. Enhanced Capabilities and Challenges One distinguishing feature of BlenderBot 3 is its ability to search the internet for information on specific topics and cite its sources in responses. By releasing the chatbot to the public, Meta intends to gather feedback to address these challenges. Users can report suspect responses and provide feedback, with Meta emphasizing efforts to minimize vulgar language and culturally insensitive remarks. Learning Approach and Differentiation Crucially, BlenderBot 3 differs from previous attempts at public AI chatbots like Microsoft's Tay. Unlike Tay, which learned in real-time from user interactions, BlenderBot 3 is a static model capable of remembering within-session conversation data but uses this information solely to enhance its performance later, without real-time learning. Implementation Hey there! Ever wondered how you can chat with a cutting-edge AI model using Python? Let's delve into it! First off, we need to equip ourselves with the right tools. We'll be using BlenderBot, a powerful conversational AI model. To get started, we'll import two crucial components from the transformers library: BlenderbotTokenizer and BlenderbotForConditionalGeneration. Additionally, we'll need torch for some backend work. from transformers import BlenderbotTokenizer, BlenderbotForConditionalGeneration import torch from IPython.display import HTML, display Now that we've got our gear ready, let's load up BlenderBot and its tokenizer. This tokenizer helps BlenderBot understand our messages, while the model itself generates responses based on those inputs. blender_model = BlenderbotForConditionalGeneration.from_pretrained("facebook/blenderbot-3B") blender_tokenizer = BlenderbotTokenizer.from_pretrained("facebook/blenderbot-3B") To make our chat experience visually appealing, we'll set up some HTML styling. This will create a neat display for our conversation, with different colors for messages from the user and the bot. style = """ """ Now, let's kick off the chat session! We'll keep it going until the user decides to exit by typing 'q' or 'quit'. During each interaction, we'll prompt the user for input and then process it using BlenderBot's tokenizer. The model will then generate a response, which we'll display in our HTML-styled chat interface. chat_log = "" chat_display = display(HTML(f"{style}{chat_log}"), display_id=True) while True: message = input("INPUT: ") if message in ["", "q", "quit"]: break chat_log += f"{message}" inputs = blender_tokenizer([message], return_tensors='pt') reply_ids = blender_model.generate(**inputs) reply = blender_tokenizer.batch_decode(reply_ids, skip_special_tokens=True)[0] chat_log += f"{reply}" chat_display.update(HTML(f"{style}{chat_log}")) Putting it All Together from transformers import BlenderbotTokenizer, BlenderbotForConditionalGeneration import torch from IPython.display import HTML, display blender_model = BlenderbotForConditionalGeneration.from_pretrained("facebook/blenderbot-3B") blender_tokenizer = BlenderbotTokenizer.from_pretrained("facebook/blenderbot-3B") style = """ """ chat_log = "" chat_display = display(HTML(f"{style}{chat_log}"), display_id=True) while True: message = input("INPUT: ") if message in ["", "q", "quit"]: break chat_log += f"{message}" inputs = blender_tokenizer([message], return_tensors='pt') reply_ids = blender_model.generate(**inputs) reply = blender_tokenizer.batch_decode(reply_ids, skip_special_tokens=True)[0] chat_log += f"{reply}" chat_display.update(HTML(f"{style}{chat_log}")) Output Pros of BlenderBot 3 Advanced Natural Language Understanding: BlenderBot 3 leverages state-of-the-art natural language processing techniques to engage in nuanced and contextually relevant conversations with users. Versatility: The chatbot is designed to handle a wide range of topics, from casual chitchat to more informational queries, making it suitable for various user needs and preferences. Transparency and Accountability: BlenderBot 3 is capable of citing its sources when providing information, enhancing transparency and allowing users to verify the accuracy of responses. Feedback Mechanism: Users have the opportunity to provide feedback on the chatbot's responses, enabling Meta to iteratively improve its performance and address any issues or shortcomings. Cons of BlenderBot 3 Biases and Inaccuracies: Like other large language models, BlenderBot 3 may inadvertently reproduce biases present in its training data and occasionally provide inaccurate or misleading responses. Limited Availability: As of now, access to BlenderBot 3 is restricted to residents of the United States, limiting its reach and potential user base. Privacy Concerns: Users who opt-in to have their data collected may have concerns about privacy and data security, especially considering the sensitive nature of conversational data. Dependency on Internet Search: BlenderBot 3 relies on internet search capabilities to provide information on specific topics. While this enhances its knowledge base, it also introduces dependency on external sources and potential issues with data quality or relevance. And that's the end! 🎉 We've finished our BlenderBot Introduction and Implementation Guide journey. We really hope this guide helped you learn useful stuff. Now that you understand BlenderBot, you've figured out how to use it to have cool conversations.

Welcome aboard, knowledge seekers! Ever wonder how to fine-tune those language models that sometimes seem to spin tales out of thin air? Well, here's the scoop – we're about to unravel the magic behind Retrieval Enhanced Generative Question Answering with none other than OpenAI and the powerhouse, Pinecone vector databases. In this tutorial, we will be working to achieve accuracy and reliability in AI responses. Get ready to explore how querying relevant contexts through Pinecone and feeding them into OpenAI's generative model can ground your answers in the real data universe. It's time to level up your understanding of language models – OpenAI and Pinecone style! Retrieval Augmented Generation (RAG) First, let's understand what Retrieval Augmented Generation (RAG) is all about. Picture this: you have a question, and you want an answer – but not just any answer, one that's not only accurate but also rooted in real-world data. That's where RAG swoops in like a superhero. It's a groundbreaking approach that marries the power of retrieval – think fetching relevant information from vast databases like Pinecone's vector databases – with the finesse of generative models, such as those crafted by OpenAI. In simpler terms, RAG is like having a super-smart librarian who not only knows where to find the right books but can also write custom responses based on them. Intrigued? Let's dive deeper into the mechanics of RAG and discover how it's revolutionizing the world of question answering. At its core, RAG represents a paradigm shift in how we approach question answering. Rather than relying solely on generative models to conjure responses from scratch, RAG leverages the vast reservoirs of knowledge stored in retrieval databases, such as the robust vector databases that we will be dealing with in this tutorial. Prerequisites To get started with the tutorial, ensure you have the following prerequisites installed: Python Environment: Ensure you have Python installed on your system. This tutorial assumes familiarity with Python programming. API Keys: OpenAI API Key: You'll need an API key from OpenAI. You can obtain one from the OpenAI platform.  Enter the key where required in the code. Pinecone API Key: Similarly, you'll require a Pinecone API key, which you can obtain from the Pinecone platform. Step 1: Installing Libraries Before we can proceed with building our question answering system, we need to make sure that we have all the necessary libraries installed. In this step, we'll install the required dependencies using pip. Code: # installing required libraries !pip install -qU \ openai==0.27.7 \ pinecone-client==3.0.0 \ pinecone-datasets==0.7.0 \ tqdm This ensures that we have access to the necessary functionality and tools needed to build and run our question answering system. Once the installation is complete, we can move on to the next steps of the process. Step 2: Building a Knowledge Base In this step, we lay the groundwork for our question answering system by creating a knowledge base. This involves retrieving relevant information from Pinecone's vector databases and organizing it for efficient retrieval. Code: from pinecone_datasets import load_dataset dataset = load_dataset('youtube-transcripts-text-embedding-ada-002') # we drop sparse_values as they are not needed for this example dataset.documents.drop(['metadata'], axis=1, inplace=True) dataset.documents.rename(columns={'blob': 'metadata'}, inplace=True) dataset.head() Step 3: Initializing Pinecone Index The next step is to initialize our connection to Pinecone and create a new index to store our embeddings. This index will serve as the backbone of our retrieval system, allowing us to efficiently query and retrieve relevant information. We first initialize our connection to Pinecone using its API key. Code: from pinecone import Pinecone # initialize connection to pinecone (get API key at app.pc.io) api_key = os.environ.get('PINECONE_API_KEY') or 'PINECONE_API_KEY' environment = os.environ.get('PINECONE_ENVIRONMENT') or 'PINECONE_ENVIRONMENT' # configure client pc = Pinecone(api_key=api_key) Before initializing the Pinecone index, we need to configure the specifications for our deployment. Depending on whether we choose a serverless or pod-based deployment, the configuration parameters will vary. Serverless and pod-based deployments are two different approaches to hosting and managing applications in a cloud environment. In a serverless deployment, the cloud provider manages the infrastructure for running the application, and developers only need to focus on writing and deploying code. Serverless platforms automatically scale resources up or down based on demand, and users are billed based on usage rather than fixed infrastructure costs. On the other hand, in a pod-based deployment, developers have more control over the underlying infrastructure, typically using container orchestration platforms like Kubernetes. Pods are groups of one or more containers that share resources and network space, providing greater flexibility and control over deployment configurations. While serverless deployments are simpler and more cost-effective for small-scale applications with unpredictable traffic patterns, pod-based deployments offer more customization and scalability options for larger and more complex applications. In this tutorial we will be using the serverless deployment. For serverless, we specify the cloud provider and region, while for pod-based deployment, we use the environment variable. Let's take a closer look at how we set up these specifications: Code: from pinecone import ServerlessSpec, PodSpec import os use_serverless = True if use_serverless: cloud = os.environ.get('PINECONE_CLOUD') or 'PINECONE_CLOUD' spec = ServerlessSpec(cloud='aws', region='us-west-2') else: spec = PodSpec(environment=environment) Here, we import the ServerlessSpec and PodSpec classes from the Pinecone library. These classes represent the specifications for serverless and pod-based deployments, respectively. We then define the name of our index as 'gen-qa-openai-fast'. Code: index_name = 'gen-qa-openai-fast' This is the last step in the creation of our index. Before proceeding, we need to ensure that the index doesn't already exist. Here's how we handle this check: Code: # check if index already exists (it shouldn't if this is first time) if index_name not in pc.list_indexes().names(): # if does not exist, create index pc.create_index( index_name, dimension=1536, # dimensionality of text-embedding-ada-002 metric='cosine', spec=spec ) And now we create our index. Code: # connect to index index = pc.Index(index_name) # view index stats index.describe_index_stats() Once the index is created (or if it already exists), we connect to it using pc.Index(index_name). This allows us to interact with the index and perform operations such as querying and updating. Finally, to ensure that the index was successfully created and to gather some basic statistics about it, we use the describe_index_stats() method on the index object. This provides information such as the number of vectors stored in the index and its current utilization, helping us confirm that the index setup was successful. Step 4: Populating the Index with Data In this step, we add our precomputed language model embeddings to the Pinecone index. By populating the index with our data, we create a searchable database that will enable us to efficiently retrieve relevant information for our question answering system. Code: for batch in dataset.iter_documents(batch_size=100): index.upsert(batch) By iterating through the dataset in batches and adding the embeddings to the index using the upsert() method, we create a searchable database that forms the foundation of our question answering system. The upsert() method both inserts new documents and updates existing ones if they are already present in the index. This indexing process ensures that our system can efficiently retrieve relevant information when queried, enabling accurate and timely responses to user questions. Step 5: Retrieval In this step, we're going to witness the power of OpenAI's text-embedding model to find the most relevant contexts for our queries. First things first, we need to set up our OpenAI environment. We initialize the text-embedding model and get ready to roll. Now, imagine you've got a burning question, something like, "Which training method should I use for sentence transformers when I only have pairs of related sentences?" That's our query. Code: import openai # get api key from platform.openai.com openai.api_key = os.getenv('OPENAI_API_KEY') or 'sk-...' embed_model = "text-embedding-ada-002" Using OpenAI's text-embedding-ada-002 model, we transform this query into a numerical representation called a query vector. Think of it as a unique fingerprint that captures the essence of our question. Now, armed with this vector, we're ready to search our Pinecone index for the juiciest bits of information. Code: query = ( "Which training method should I use for sentence transformers when " + "I only have pairs of related sentences?" ) res = openai.Embedding.create( input=[query], engine=embed_model ) We then fire off our query to the index, asking it to find the top two most relevant contexts. Code: # retrieve from Pinecone xq = res['data'][0]['embedding'] # get relevant contexts (including the questions) res = index.query(vector=xq, top_k=2, include_metadata=True) res Once Pinecone does its thing, we get back a response with the relevant contexts neatly packaged up for us. It's like having the most relevant passages from a library handed to us on a silver platter. Now, armed with this wealth of information, our question answering system is ready to tackle even the toughest of queries with confidence and accuracy. Step 6: Handling Retrieval and Completion Now that we've retrieved the relevant contexts from our Pinecone index, it's time to handle the retrieval and completion steps of the question answering process. In this step, we'll define functions to manage the retrieval and completion steps seamlessly. We've defined this nifty function called retrieve(). Its job is to fetch all the relevant bits of information for a given query. Imagine it as our trusty assistant scouring through a library to find the perfect books for our research. Code: limit = 3750 import time def retrieve(query): res = openai.Embedding.create( input=[query], engine=embed_model ) # retrieve from Pinecone xq = res['data'][0]['embedding'] # get relevant contexts contexts = [] time_waited = 0 while (len(contexts) < 3 and time_waited < 60 * 12): res = index.query(vector=xq, top_k=3, include_metadata=True) contexts = contexts + [ x['metadata']['text'] for x in res['matches'] ] print(f"Retrieved {len(contexts)} contexts, sleeping for 15 seconds...") time.sleep(15) time_waited += 15 if time_waited >= 60 * 12: print("Timed out waiting for contexts to be retrieved.") contexts = ["No contexts retrieved. Try to answer the question yourself!"] # build our prompt with the retrieved contexts included prompt_start = ( "Answer the question based on the context below.\n\n"+ "Context:\n" ) prompt_end = ( f"\n\nQuestion: {query}\nAnswer:" ) # append contexts until hitting limit for i in range(1, len(contexts)): if len("\n\n---\n\n".join(contexts[:i])) >= limit: prompt = ( prompt_start + "\n\n---\n\n".join(contexts[:i-1]) + prompt_end ) break elif i == len(contexts)-1: prompt = ( prompt_start + "\n\n---\n\n".join(contexts) + prompt_end ) return prompt Alright, now that we've got our relevant contexts, it's time to put them to good use with our complete() function. This function is like the finishing touch, where we take those contexts and generate a beautifully crafted response. Code: def complete(prompt): # instructions sys_prompt = "You are a helpful assistant that always answers questions." # query text-davinci-003 res = openai.ChatCompletion.create( model='gpt-3.5-turbo-0613', messages=[ {"role": "system", "content": sys_prompt}, {"role": "user", "content": prompt} ], temperature=0 ) return res['choices'][0]['message']['content'].strip() And there you have it! With our retrieve() and complete() functions working in tandem, we've got a powerful system ready to provide accurate and contextually relevant answers to any query thrown its way. It's like having your own personal research assistant at your beck and call! Now that we have defined these utility functions its time to put them to use. We use the retrieve() function to fetch relevant contexts based on a user query. This function takes the query as input, generates a prompt with the retrieved contexts, and returns the formatted prompt. Code: # first we retrieve relevant items from Pinecone query_with_contexts = retrieve(query) query_with_contexts Next, we pass the retrieved prompt to the complete() function, which generates a response using OpenAI's ChatCompletion model. This function completes the context-infused query and returns the generated response. Code: # then we complete the context-infused query complete(query_with_contexts) Step 7: Finalizing and Cleaning Up In this final step, we'll wrap things up by finalizing our system and cleaning up any resources we no longer need. It's always good practice to tidy up after ourselves and ensure everything is in order. Code: pc.delete_index(index_name) After we've completed our question-answering tasks and no longer need the Pinecone index, we call the delete_index() method to remove it. Deleting the index helps to free up resources and avoid unnecessary costs associated with maintaining unused indexes. This step ensures that we're being efficient with our resources and keeping our environment tidy. In this tutorial, we explored retrieval-enhanced generative question answering using OpenAI and Pinecone. By combining the strengths of retrieval-based search with generative language models, we've created a powerful system capable of providing accurate and contextually relevant answers to a wide range of queries. Throughout our journey, we've learned how to set up a Pinecone index to store and efficiently retrieve information, utilize OpenAI's text-embedding model to retrieve relevant contexts, and use advanced language models to generate responses based on these contexts. We've seen how each step contributes to the overall effectiveness of our question-answering system, from data indexing to response generation. With this newfound knowledge, the possibilities are endless. Whether it's enhancing customer support systems, building intelligent chatbots, or facilitating information retrieval in complex datasets, retrieval-enhanced generative question answering opens up a world of opportunities for innovation and problem-solving. As we conclude this tutorial, remember that the key to success lies in experimentation and iteration. Don't be afraid to explore different approaches, tweak parameters, and fine-tune your system to suit your specific needs. With dedication and creativity, you'll witness the full potential of retrieval-enhanced generative question answering and can possibly transform the way we interact with information in the digital age.

Fear not, intrepid explorer of the digital realm, for we have just the solution to your woes! In this blog, we'll take you on a journey through the ins and outs of semantic search using Pinecone, enabling you to work on vast data with ease and finesse. So grab your metaphorical compass, buckle up, and get ready to embark on a voyage of discovery unlike any other! Pinecone Pinecone is a cloud-native vector database designed to streamline and accelerate the process of building and deploying applications that rely on similarity search and recommendation systems. It provides a robust infrastructure for storing, indexing, and querying high-dimensional vector embeddings, allowing developers to efficiently retrieve nearest neighbors or similar items based on vector representations. At its core, Pinecone leverages state-of-the-art indexing techniques and scalable infrastructure to handle large volumes of high-dimensional data effectively. It offers a simple yet powerful API that abstracts away the complexities of managing vector databases, making it easy for developers to integrate semantic search capabilities into their applications with minimal effort. In essence, Pinecone stands as a versatile ally for those eager to tap into the potential of vector databases. Whether you're crafting recommendation engines, curating content discovery platforms, or fine-tuning personalized search experiences, Pinecone acts as a catalyst, swiftly transforming raw data into tangible insights with remarkable speed and efficiency. Now that we've familiarized ourselves with Pinecone, it's time to roll up our sleeves and delve into the practical aspects of this powerful tool. So, without further ado, let's start this tutorial on using Pinecone for semantic search. A Practical Guide to Semantic Search using Pinecone To begin we must install the required prerequisite libraries: Step 1: Install Required Libraries Alright, let's kick things off by making sure we have all the tools we need to dive into semantic search using Pinecone. To get started, we'll need to install a few essential libraries. These libraries are like the secret sauce that makes everything tick behind the scenes. We'll be installing three key ingredients: pinecone-client, pinecone-datasets, and sentence-transformers. These are the building blocks that we will be utilizing to use Pinecone for our semantic search adventure. Code: !pip install -qU \ pinecone-client==3.0.0 \ pinecone-datasets==0.7.0 \ sentence-transformers==2.2.2 (Now, here's a little trick: if you're working within a Jupyter notebook, you can simply run the provided pip install command with an exclamation mark (!). But if you're coding in a different environment, just drop the ! and run the command as is.) Step 2: Downloading the data Now that we've got our toolkit all set up, it's time to get our hands on some data. But hold your horses! We're going to take a shortcut here to save us some precious time. Instead of tediously preparing our own dataset ( which can be incredibly time-consuming and might even warrant its own separate blog post), we're going to tap into Pinecone's treasure trove of prebuilt datasets. Think of it like having access to a ready-made library of information. The dataset used in this tutorial is derived from Quora questions and answers, which have been preprocessed and encoded using the MiniLM-L6 model and BM25 ranking. Code: from pinecone_datasets import load_dataset dataset = load_dataset('quora_all-MiniLM-L6-bm25') # we drop metadata as will use blob column dataset.documents.drop(['metadata'], axis=1, inplace=True) dataset.documents.rename(columns={'blob': 'metadata'}, inplace=True) # we will use 80K rows of the dataset between rows 240K -> 320K dataset.documents.drop(dataset.documents.index[320_000:], inplace=True) dataset.documents.drop(dataset.documents.index[:240_000], inplace=True) dataset.head() Each entry in the dataset represents a question from Quora, along with its corresponding answer. The dataset is structured such that each question-answer pair is treated as a single document, with the question serving as the main content and the answer as supplementary information. The dataset has undergone preprocessing to ensure consistency and compatibility with the semantic search task. This includes tokenization, encoding, and ranking using the MiniLM-L6 model and BM25 algorithm. Step 3: Serverless or Pod-based? We now have our dataset ready to go, it's time to decide how we want to deploy our index. This decision boils down to whether we want to use a serverless or pod-based approach. If you're unfamiliar with these terms, let me break it down for you. A serverless index is managed by Pinecone and runs on their infrastructure, allowing for seamless scalability and minimal maintenance overhead. On the other hand, a pod-based index is deployed on your own Kubernetes cluster, giving you more control over the environment and potentially better performance for high-throughput applications. To make this decision, we need to consider factors like scalability, resource management, and cost. If you're just getting started and want to keep things simple, a serverless index is the way to go. But if you have specific requirements or need more control over the deployment environment, a pod-based index might be the better choice. In this tutorial, we are using a serverless approach. Code: import os use_serverless = os.environ.get("USE_SERVERLESS", "False").lower() == "true" Step 4: Creating an Index With our dataset prepared and our deployment approach decided, it's time to set up our index in Pinecone. First, we'll initialize our connection to Pinecone using our API key. If you haven't already obtained your API key, you can sign up for a free account on the Pinecone website to get one. Code: from pinecone import Pinecone # initialize connection to pinecone (get API key at app.pc.io) api_key = os.environ.get('PINECONE_API_KEY') or 'PINECONE_API_KEY' environment = os.environ.get('PINECONE_ENVIRONMENT') or 'PINECONE_ENVIRONMENT' # configure client pc = Pinecone(api_key=api_key) Next, we'll specify the configuration for our index. This includes parameters such as the dimensionality of the vectors, the distance metric to use for similarity calculations, and the deployment specification (serverless or pod-based). Code: from pinecone import ServerlessSpec, PodSpec if use_serverless: spec = ServerlessSpec(cloud='aws', region='us-west-2') else: spec = PodSpec(environment=environment) Once our index specification is ready, we'll create the index. Pinecone will handle the deployment and initialization process, ensuring that our index is ready for use. We'll give it a name, define the dimensionality of the vectors (matching the embeddings we'll be using), specify the distance metric, and provide the deployment specification. Code: import time index_name = 'semantic-search-fast' existing_indexes = [ index_info["name"] for index_info in pc.list_indexes() ] # check if index already exists (it shouldn't if this is first time) if index_name not in existing_indexes: # if does not exist, create index pc.create_index( index_name, dimension=384, # dimensionality of minilm metric='dotproduct', spec=spec ) # wait for index to be initialized while not pc.describe_index(index_name).status['ready']: time.sleep(1) # connect to index index = pc.Index(index_name) time.sleep(1) # view index stats index.describe_index_stats() We have now created a new index called 'semantic-search-fast'. It's important that we align the index dimension and metric parameters with those required by the MiniLM-L6 model. Step 5: Upserting Data into the Index Now that our index is created, it's time to populate it with our dataset. This process, known as "upserting," involves inserting new data points into the index or updating existing ones if they already exist. Once the dataset is upserted into the index, we'll be ready to perform semantic search queries to retrieve relevant documents based on input queries. This marks a crucial step in our journey towards building a powerful semantic search engine using Pinecone. We'll iterate through our dataset in batches and upsert each batch into the index. This ensures efficient processing and minimizes resource usage. Code: from tqdm.auto import tqdm for batch in tqdm(dataset.iter_documents(batch_size=500), total=160): index.upsert(batch) Note: The tqdm module is used to display a progress bar, providing visibility into the upserting process. Step 6: Making Queries With our dataset upserted into the index, we can now start making queries to retrieve relevant documents based on input queries. In this step, we'll perform semantic search queries using Pinecone to find similar documents to a given input query. First, we'll need to prepare our query by encoding it into a vector representation using a pre-trained sentence embedding model. We'll use the SentenceTransformer library to encode our query. Code: from sentence_transformers import SentenceTransformer import torch device = 'cuda' if torch.cuda.is_available() else 'cpu' model = SentenceTransformer('sentence-transformers/all-MiniLM-L6-v2', device=device) query = "which city has the highest population in the world?" # create the query vector xq = model.encode(query).tolist() Next, we'll use the encoded query vector to perform a semantic search query on our index. We'll specify the number of similar documents (top_k) to retrieve and include metadata in the query response to obtain additional information about the retrieved documents. Now, lets query. Code: # now query xc = index.query(vector=xq, top_k=5, include_metadata=True) Upon receiving the response in variable xc, we observe a collection of questions closely related to our initial query. While we may not have exact matches, it's evident that the retrieved questions share common themes and topics. To enhance readability, we can opt to reformat this response for better clarity and comprehension. Code: for result in xc['matches']: print(f"{round(result['score'], 2)}: {result['metadata']['text']}") Let us look at one more example query search. Code: query = "which metropolis has the highest number of people?" # create the query vector xq = model.encode(query).tolist() # now query xc = index.query(vector=xq, top_k=5, include_metadata=True) for result in xc['matches']: print(f"{round(result['score'], 2)}: {result['metadata']['text']}") In this demonstration, we intentionally utilized distinct terms in our query compared to those found in the retrieved documents. Specifically, we replaced "city" with "metropolis" and "populated" with "number of people." Remarkably, despite the considerable disparity in terms and the absence of direct term overlap between the query and the retrieved documents, the results remained highly relevant. This exemplifies the remarkable capability of semantic search algorithms to comprehend contextual similarities beyond literal word matching. Step 8: Index Deletion In this final step, we will tidy up our environment by deleting the index. After completing our experimentation and queries, it's essential to clean up resources to avoid unnecessary costs and clutter. To delete the index, we'll utilize the Pinecone client library to issue a deletion command: Code: pc.delete_index(index_name) With the index successfully deleted, we've concluded our tutorial on semantic search using Pinecone. Ta-da! 🎉 So, with this, we wrap up our tutorial journey. We sincerely hope that this tutorial has been both insightful and practical for you.

Are you hearing about vector databases everywhere you turn, yet find yourself scratching your head, wondering what all the fuss is about? You're not alone! The buzz around vector databases can be overwhelming, leaving many of us feeling a bit lost in the jargon jungle. But fear not, because we're here to shed some light on this fascinating topic. In this blog, we'll break down the concept of vector databases into bite-sized pieces, making it easy for you to understand and appreciate their significance. So, buckle up and get ready to embark on a journey of discovery with us! In data management, traditional databases have long reigned supreme. Picture them as meticulously organized libraries, where data is neatly stored in rows and columns, akin to books neatly stacked on shelves. This structure, while effective, can sometimes feel limiting, especially when it comes to handling complex data relationships or searching for nuanced patterns. Enter vector databases, the game-changers in the world of data storage and retrieval. Unlike their traditional counterparts, which rely on structured tables, vector databases take a radically different approach by leveraging vectors – mathematical representations of data points in multidimensional space. This departure from the conventional row-and-column model opens up a world of possibilities, allowing for more flexible and efficient data handling. Vectors At the heart of vector databases lies the concept of vectors – not the arrows in your high school math class, but mathematical representations which are famously known as Vector Embeddings that pack a punch in the data world. These embeddings serve as the building blocks of the database, transforming raw data into multidimensional vectors that capture the essence of each data point. But what exactly are vector embeddings? Vector embedding, often used in the context of machine learning and natural language processing, is a technique to represent high-dimensional data in a lower-dimensional space, typically as dense vectors of fixed length. The goal of vector embedding is to capture the inherent structure and relationships within the data in a more compact form that preserves semantic similarities. This is achieved through techniques like Word2Vec, GloVe, or FastText, which learn vector representations of words based on their co-occurrence patterns in large text corpora. These embeddings capture semantic relationships between words, such as similarity and analogy, similar words are mapped closer together in the vector space. Think of them as compact representations of data that encode rich information about the underlying features and relationships. For example: In natural language processing (NLP), words can be embedded into high-dimensional vectors where similar words are mapped closer together in vector space, capturing semantic similarities. Similarly, in image processing, images can be represented as vectors where similar images are grouped together based on visual similarities. These embeddings form the backbone of vector databases, enabling efficient storage, retrieval, and manipulation of data in a way that traditional databases simply cannot match. Vector Databases Now, let's try to understand how these vector embeddings come together to form vector databases. At the core of a vector database lies a sophisticated indexing system that organizes these embeddings in a way that facilitates fast and efficient querying. Vector databases leverage vector embeddings as a fundamental building block for organizing and querying data efficiently. The process of building a vector database involves several key steps: Generating Vector Embeddings: The first step is to generate vector embeddings for the data to be stored in the database. This typically involves representing each data point as a dense vector of fixed length. In natural language processing, for example, words or phrases are often represented as word embeddings, while in image processing, images may be represented as image embeddings. Techniques such as Word2Vec, GloVe, or convolutional neural networks (CNNs) are commonly used to generate these embeddings. Indexing Vector Embeddings: Once the vector embeddings are generated, they are indexed and organized within the database to facilitate efficient querying. This indexing process involves structuring the vector embeddings in a way that enables fast retrieval of similar vectors or nearest neighbors. Various indexing techniques, such as metric trees (e.g., k-d trees, ball trees), inverted indices, or locality-sensitive hashing (LSH), may be employed depending on the characteristics of the data and the desired query performance. Querying and Retrieval: With the vector embeddings indexed, the database can efficiently handle queries that involve searching for similar vectors or retrieving nearest neighbors. Given a query vector, the database utilizes its indexing structure to quickly identify candidate vectors that are similar to the query. This allows for fast retrieval of relevant data points based on their vector similarities, enabling tasks such as recommendation, search, or clustering. Updating and Maintenance: Vector databases may also incorporate mechanisms for updating and maintaining the vector embeddings as new data points are added or existing ones are modified. This ensures that the database remains up-to-date and reflects changes in the underlying data distribution over time. Techniques such as incremental indexing or re-indexing may be employed to efficiently update the database while minimizing disruption to query performance. Traditional databases rely on structured indices like B-trees or hash tables, which work well for exact matches but struggle with complex queries or similarity searches. Vector databases, on the other hand, leverage advanced indexing techniques tailored for vector spaces. One such technique is the use of metric trees, also known as similarity search trees, which partition the vector space into hierarchical structures that enable efficient nearest neighbor searches. By computing the similarity between vectors, the database can identify relevant data points that closely match a given query, even in high-dimensional spaces. This opens up a world of possibilities for applications such as recommendation systems, content-based search, and anomaly detection. Another approach is the use of inverted indices, where embeddings are indexed based on their components, allowing for lightning fast retrieval of similar vectors. By utilizing vector embeddings and specialized indexing techniques, vector databases empower users to explore vast amounts of data with unprecedented speed and accuracy, opening up new frontiers in data-driven decision-making and discovery. In essence, vector databases represent a paradigm shift in data management, offering a more flexible, scalable, and intelligent approach to storing and querying data. Advantages of Vector Databases Efficient Similarity Search: Vector databases excel at similarity searches, enabling users to quickly find nearest neighbors or similar items based on vector representations. This makes them ideal for applications such as recommendation systems, image retrieval, and anomaly detection. High-Dimensional Data Handling: Unlike traditional databases, vector databases can efficiently handle high-dimensional data, making them well-suited for tasks like natural language processing, genomic analysis, and image processing, where data complexity is inherent. Flexibility and Scalability: Vector databases offer flexibility in representing diverse types of data as vectors, allowing for seamless integration of various data formats. Moreover, they can scale effortlessly to handle large volumes of data, making them suitable for growing datasets and high-throughput applications. Advanced Indexing Techniques: Leveraging specialized indexing techniques tailored for vector spaces, vector databases optimize query performance and enable fast retrieval of similar vectors, enhancing overall efficiency and speed. Limitations of Vector Databases Complexity in Model Training: While vector databases offer powerful capabilities for similarity search and data retrieval, the process of training vector embeddings can be computationally intensive and requires careful optimization. Training large-scale embedding models may also necessitate substantial computational resources. Data Representation Challenges: Representing complex data structures as vectors may pose challenges, particularly in capturing nuanced relationships and semantics. In some cases, oversimplification or loss of information during vectorization may lead to suboptimal performance in certain tasks. Dimensionality Curse: Handling high-dimensional data in vector databases can sometimes be challenging due to the "curse of dimensionality." As the dimensionality of the data increases, the computational complexity of similarity searches and indexing grows exponentially, potentially impacting query performance and efficiency. Domain-Specific Expertise Required: Effectively leveraging vector databases often requires domain-specific expertise in areas such as data modeling, vectorization techniques, and query optimization. Organizations may need to invest in specialized talent or training to fully harness the potential of these databases. While vector databases offer numerous advantages in handling complex data and enabling advanced analytics, they also come with inherent challenges that require careful consideration and strategic implementation. By weighing the pros and cons, organizations can make informed decisions about adopting vector databases and leveraging them to unlock valuable insights from their data. Practical Applications of Vector Databases Now that we've gained a deeper understanding of vector databases and their underlying principles, let's explore some real-world applications where they shine brightly. Personalized Recommendations: One of the most prominent applications of vector databases is in personalized recommendation systems. By representing users, items, and their interactions as vectors, these databases can efficiently calculate similarities and make tailored recommendations. Whether it's suggesting movies on streaming platforms, products on e-commerce websites, or articles on news portals, vector databases enable businesses to deliver personalized experiences that keep users engaged and satisfied. Image Search and Similarity Detection: In the realm of computer vision, vector databases are powering advanced image search and similarity detection applications. By encoding images as vectors, these databases allow users to search for visually similar images with remarkable accuracy. Whether it's finding visually similar products in an online marketplace or identifying similar images in a vast collection, vector databases enable fast and efficient image retrieval, paving the way for enhanced visual search experiences. Natural Language Processing (NLP): In the field of NLP, vector databases are playing a pivotal role in semantic search and text analysis tasks. By embedding words, phrases, and documents into high-dimensional vector representations, these databases facilitate semantic similarity searches, document clustering, and sentiment analysis. From powering chatbots and virtual assistants to enabling sophisticated text search capabilities, vector databases are revolutionizing how we interact with and derive insights from textual data. Anomaly Detection and Fraud Prevention: Vector databases are also finding applications in anomaly detection and fraud prevention across various domains. By representing normal and abnormal behavior patterns as vectors, these databases enable organizations to detect deviations from expected norms and flag potentially fraudulent activities in real-time. Whether it's identifying suspicious transactions in financial systems or detecting anomalies in network traffic, vector databases empower businesses to proactively mitigate risks and safeguard their assets. Genomic Data Analysis: The field of genomics relies heavily on managing and analyzing vast datasets. Vector databases, with their ability to handle high-dimensional data, prove instrumental in genomics research. They facilitate the comparison of genetic sequences, identification of gene expressions, and exploration of relationships within complex genomic datasets. These are just a few examples of the diverse applications of vector databases in today's data-driven world. As technology continues to evolve and data volumes grow exponentially, the role of vector databases will only become more prominent, driving innovation and unlocking new possibilities across industries.
