RAG Retrieval Techniques

This project demonstrates various retrieval techniques for document retrieval using Python. The techniques implemented include HyDe, Basic, Reciprocal Rank Fusion (RRF), Fusion Retrieval and Sub Query Decomposition(SQD). The project uses Streamlit for the user interface and various libraries for document processing and retrieval.

Retrieval Techniques

HyDe

HyDe (Hypothetical Document) retrieval generates a hypothetical document based on the query and retrieves similar documents.

Basic

Basic retrieval uses a simple similarity search to retrieve documents based on the query.

RRF

Reciprocal Rank Fusion (RRF) combines the results of multiple retrieval algorithms to improve the overall retrieval performance.

Fusion

Fusion retrieval combines vector search and BM25 search results using a weighted sum to retrieve the most relevant documents.

Sub Query Decomposition

Sub Query Decomposition (SQD) is a technique that decomposes the query into sub-queries and retrieves documents based on the sub-queries.
