Overview

Welcome to the LangChain course. LangChain is a framework designed to build applications powered by large language models (LLMs). It provides tools and abstractions to make it easier to integrate LLMs into applications, enabling tasks like question answering, text generation, retrieval-augmented generation (RAG), chatbots, and more.

What you'll learn

  • Learn LangChain from scratch
  • Understand the LangChain workflow
  • Summarize multiple PDF documents with LangChain and RAG
  • Understand chaining in LangChain
  • Get to know the LangChain components with examples
  • Load and parse the PDF documents
  • Split documents into chunks
  • Setup the embedding models
  • Learn to create a vector store from the document chunks
  • Setup a local LLM
  • Learn to create a QA chain

Description

Learn LangChain and its components. Implement LangChain with RAG to understand the workflow and set up a Question-Answering chain.

LangChain – Use Cases

Here are some of the use cases of LangChain:

  1. Question Answering: Build systems that answer questions by retrieving relevant information and generating answers using LLMs.
  2. Chatbots: Create conversational agents that can maintain context across interactions.
  3. Retrieval-Augmented Generation (RAG): Combine retrieval of relevant documents with text generation for more accurate and context-aware responses.
  4. Text Summarization: Generate summaries of long documents or articles.
  5. Code Generation: Build tools that generate code based on natural language descriptions.
  6. Personal Assistants: Create virtual assistants that can perform tasks like scheduling, email drafting, or information retrieval.

A regulated qualification is delivered by a learning institution which is regulated by a government body. In England, the government body which regulates courses is Ofqual. Ofqual regulated qualifications sit on the Regulated Qualifications Framework (RQF), which can help students understand how different qualifications in different fields compare to each other. The framework also helps students to understand what qualifications they need to progress towards a higher learning goal, such as a university degree or equivalent higher education award.

An endorsed course is a skills based course which has been checked over and approved by an independent awarding body. Endorsed courses are not regulated so do not result in a qualification - however, the student can usually purchase a certificate showing the awarding body's logo if they wish. Certain awarding bodies - such as Quality Licence Scheme and TQUK - have developed endorsement schemes as a way to help students select the best skills based courses for them.
