๐ This video explains the process of building an end-to-end LLM project for equity research analysis using Langchain, OpenAI, and Streamlit.
๐ฆ The project involves creating a news research tool that can retrieve answers and summaries based on a given set of news article URLs.
๐ก The tool addresses the challenges of copy-pasting articles, finding relevant information, and the word limit of chat GPT by using a knowledge base and smartly selecting chunks of text to optimize costs.
Vector databases help in performing faster searches.
Building a project in streamlit and using POC for testing.
Architecture involves database injection system and chatbot.
๐ Text splitting is necessary to reduce the token size limit in LLM projects.
๐ Merging smaller chunks of text helps optimize efficiency in LLM projects.
๐ Overlap between chunks allows for better contextual understanding in LLM projects.
๐ The video discusses the process of creating chunks from a given text using recursive text splitter.
๐ก The video introduces the concept of using a lightweight in-memory Vector database called Phase for efficient search on vectors.
๐ The video demonstrates how to convert text into vectors using the Sentence Transformer library and perform similarity search with Phase index.
๐ Semantic search captures the context or meaning of a sentence to provide similar sentences.
๐ Langchain is a library used for storing and retrieving vectors for question-answering tasks.
โ๏ธ The retrieval QA method using Langchain involves storing vectors in a vector database and asking questions to retrieve relevant chunks.
๐ The video demonstrates how to use Langchain and OpenAI to create an end-to-end LLM project in the finance domain.
๐ The project involves loading and splitting data, generating embeddings, and creating a face index for efficient retrieval.
โ๏ธ The speaker emphasizes the importance of understanding the fundamentals and assembling the individual project components.
โ๏ธ The video demonstrates the process of using Langchain and OpenAI in a finance project.
๐ The project involves loading data, splitting it into chunks, building embeddings, and creating an index for retrieval.
๐ The tool allows users to ask questions and receive answers based on the loaded data, with sources provided.
