Harrison Chase	985496f4be	Docs refactor (#480 ) Big docs refactor! Motivation is to make it easier for people to find resources they are looking for. To accomplish this, there are now three main sections: - Getting Started: steps for getting started, walking through most core functionality - Modules: these are different modules of functionality that langchain provides. Each part here has a "getting started", "how to", "key concepts" and "reference" section (except in a few select cases where it didnt easily fit). - Use Cases: this is to separate use cases (like summarization, question answering, evaluation, etc) from the modules, and provide a different entry point to the code base. There is also a full reference section, as well as extra resources (glossary, gallery, etc) Co-authored-by: Shreya Rajpal <ShreyaR@users.noreply.github.com>	2 years ago

andersenchen	5267ebce2d	Add LLMCheckerChain (#281 ) Implementation of https://github.com/jagilley/fact-checker. Works pretty well. <img width="993" alt="Screenshot 2022-12-07 at 4 41 47 PM" src="https://user-images.githubusercontent.com/101075607/206302751-356a19ff-d000-4798-9aee-9c38b7f532b9.png"> Verifying this manually: 1. "Only two kinds of egg-laying mammals are left on the planet today—the duck-billed platypus and the echidna, or spiny anteater." https://www.scientificamerican.com/article/extreme-monotremes/ 2. "An [Echidna] egg weighs 1.5 to 2 grams (0.05 to 0.07 oz)[[19]](https://en.wikipedia.org/wiki/Echidna#cite_note-19) and is about 1.4 centimetres (0.55 in) long." https://en.wikipedia.org/wiki/Echidna#:~:text=sleep%20is%20suppressed.-,Reproduction,a%20reptile%2Dlike%20egg%20tooth. 3. "A [platypus] lays one to three (usually two) small, leathery eggs (similar to those of reptiles), about 11 mm (7⁄16 in) in diameter and slightly rounder than bird eggs." https://en.wikipedia.org/wiki/Platypus#:~:text=It%20lays%20one%20to%20three,slightly%20rounder%20than%20bird%20eggs. 4.

Samantha Whitmore	09f301cd38	Add add_example method to all ExampleSelector classes, with tests (#178 ) Also updated docs, and noticed an issue with the add_texts method on VectorStores that I had missed before -- the metadatas arg should be required to match the classmethod which initializes the VectorStores (the add_example methods break otherwise in the ExampleSelectors)	2 years ago

Harrison Chase	4a4dfbfbed	Harrison/sequential chains (#168 ) add support for basic sequential chains	2 years ago
Samantha Whitmore	315b0c09c6	wip: add method for both docstore and embeddings (#119 ) this will break atm but wanted to get thoughts on implementation. 1. should add() be on docstore interface? 2. should InMemoryDocstore change to take a list of documents as init? (makes this slightly easier to implement in FAISS -- if we think it is less clean then could expose a method to get the number of documents currently in the dict, and perform the logic of creating the necessary dictionary in the FAISS.add_texts method.

Edmar Ferreira	8a5ec894e7	Prompt from file proof of concept using plain text (#127 ) This is a simple proof of concept of using external files as templates. I'm still feeling my way around the codebase. As a user, I want to use files as prompts, so it will be easier to manage and test prompts. The future direction is to use a template engine, most likely Mako.	2 years ago
