In this tutorial we will load a PDF book, split it up into documents, get vectors for those documents as embeddings, then ask a question.
--AI Generated Description--
In this tutorial, I am is discussing how to query a book using OpenAI, LangChain, and Pinecone, an external vector store, for semantic search.
I'm demonstrating how to split up the book into documents, use OpenAI embeddings to change them into vectors, and then use Pinecone to store them externally.
I'm then showing how to ask a question and get an answer back in natural language. This technique can be used to query books as well as internal documents or external data sets.

@@areacode3816 maybe from ur pinecone reaching its limit? or ur 4000 gpt3 token limit? i would check these first, if its pinecone the fix is easy, jus buy more space, but if its due to gpt then try gpt4 it has double the token at 8k or if that doesnt work i would figure out an intermediary step in between to introduce another sumarizing algorithm before passing it to gpt3

[@aaanas]

Was the starter tier of pinecone enough for you?

[@PatrickCallaghan-yf2sf]

Its one project only on starter tier, that one project can contain multiple documents under one vector vector db. For me it was certainty enough to get an understanding of the potential. From my limited experience, to create multiple vector db's for different project types you will need to premium/paid and the cost is quite high. There may be other competitors offering cheaper entry level if you wish to develop apps but for a hobbyist/learning the starter tier on pinecone is fine IMO.

One presenter suggested 3 sentences with overlap might be a good starting point.

Pinecone is basically a search engine for ai. It doesn't need the entire book but just segments of it instead. This saves a lot of tokens cause only segments of information end up in the prompt. Like adding some information into gpt's short term memory

[@HerroEverynyan]

Hi! Awesome tutorial. This is exactly what I was looking for. I really love this series you've started and hope you'll keep it up. I also wanted to ask: 1. What's the difference between using Pinecone or another vector store like Chrome, FAISS, Weaviate, etc? And what made you choose Pinecone for this particular tutorial? 2. What was the cost for creating embeddings for this book? (time & money) 3. Is there a way to estimate the cost of embeddings with LangChain beforehand? Thank you very much and looking forward to more vids like this! 🤟

[@DataIndependent]

For your questions 1. The difference with Pinecone/Chrome,etc. Not much. They store your embeddings and they run a similarity calc for you. However the space is super new, as things progress one may be a no brainer over another. Ex: You could also do this in GCP but you'd have to deal with their overhead as well. 2. Hm, unsure about the book but here is the pricing for Ada embeddings: $0.0004 / 1K tokens. So if you had 120K word book which is ~147K tokens, it would be $.05. Not very steep... 3. Yes, you can calc the number of tokens you're going to use and the task, then look up their pricing table and see how much it'll be.

Would love to see an example of adding another book after you've done this one. What would be some of the considerations and fine-tuning you'd make as a result of the second upload

[@DataIndependent]

You could add more documents to your existing index and it shouldn't be a problem. However once you start to add a bunch of information, pre-filtering your vectors will become more important. Ex: If you know the answer comes from 1 of your 3 books then you can tell Pinecone to only return docs from that 1 book

@@DataIndependent So I'm running a shop for car parts and equipment for cars. I think, from a consumer point of view, it would be amazing if we could solve two major issues. 1. If you're browsing for something to solve your problem rather than an actual product. Say that you have some stains on your car. It would be amazing if you could just ask the Friendly Chat Support how to deal with the issue and the support AI would have all the information about all our products and all the content that we've written at hand. And could go "Yeah, so you would use this product and go about it in so and so manner". 2. It would be super cool if it also had access to user data and past purchases etc. And go "Hey.. last time you bought this and this. How did that work out for you? From 1 to 10 how much did you love it?" etc etc. -- It feels like this is a scenario that is predicated on the idea that the AI has very specific knowledge

[@valdinia-office2910]

In LangChain is "similarity search" used as a synonym for "semantic search", or they are referring to different types of search? To my knowledge similarity search focuses on finding items that are similar based on their features or characteristics, while semantic search aims to understand the meaning and intent behind the query to provide contextually relevant results

[@deanshalem]

Also, I’ve been trying to make some type of “theorems, definitions, and corollaries” assistant which extracts from my textbook all the math theorems, definitions, and corollaries. The goal there was to create textbook summaries to reference when I work through tough problems which require me to flip back and forth through my book all day long. But more interesting, I am struggling to create a “math_proofs” assistant. Your approach in this video is awesome, but I can’t find any of your resources in which you use markdown, or latex, or any mathematical textbook to be queried. I use MathPix to convert my textbooks to latex, wordDoc, or markdown. But when I use my new converted markdown text, despite working hand-in-hand with the lang chain documentation, I still fail to get a working agent that proves statements. I feed the model: “Prove the zero vector is unique” and it replies nonsense, even though this proof is explicitly written in the text. It is not even something it had to “think” to produce (simple for the sake of example, these proofs are matrix theory so they get crazy). Could you please chime in?

[@DataIndependent]

This is a great video - succinct and easy to follow. Two questions: 1) How easy is it to add more than one document to the same vector db 2) Is it possible to append an additional ... field(?) to that database table - so that the provenance of the reference can be reported back with the synethised result?
