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)

Glossary

This is a collection of terminology commonly used when developing LLM applications. It contains reference to external papers or sources where the concept was first introduced, as well as to places in LangChain where the concept is used.

Chain of Thought Prompting

A prompting technique used to encourage the model to generate a series of intermediate reasoning steps. A less formal way to induce this behavior is to include “Lets think step-by-step” in the prompt.

Resources:

Action Plan Generation

A prompt usage that uses a language model to generate actions to take. The results of these actions can then be fed back into the language model to generate a subsequent action.

Resources:

ReAct Prompting

A prompting technique that combines Chain-of-Thought prompting with action plan generation. This induces the to model to think about what action to take, then take it.

Resources:

Self-ask

A prompting method that builds on top of chain-of-thought prompting. In this method, the model explicitly asks itself follow-up questions, which are then answered by an external search engine.

Resources:

Prompt Chaining

Combining multiple LLM calls together, with the output of one-step being the input to the next.

Resources:

Memetic Proxy

Encouraging the LLM to respond in a certain way framing the discussion in a context that the model knows of and that will result in that type of response. For example, as a conversation between a student and a teacher.

Resources:

Self Consistency

A decoding strategy that samples a diverse set of reasoning paths and then selects the most consistent answer. Is most effective when combined with Chain-of-thought prompting.

Resources:

Inception

Also called “First Person Instruction”. Encouraging the model to think a certain way by including the start of the models response in the prompt.

Resources:

MemPrompt

MemPrompt maintains a memory of errors and user feedback, and uses them to prevent repetition of mistakes.
