Trade offs between Sparse and Dense Retrievers

  When implementing retrieval mechanisms in AI systems like Retrieval-Augmented Generation (RAG), choosing between sparse retrievers (e.g., BM25) and dense retrievers (e.g., Dense Passage Retrieval, DPR) is crucial. Both have their strengths and weaknesses, and the decision often depends on the specific use case, resources, and goals. Here’s a detailed comparison to help you understand

How Does RAG Differ from Traditional Question-Answering Systems?

Retrieval-Augmented Generation (RAG) represents a significant evolution in how question-answering (QA) systems are designed, combining the strengths of retrieval-based systems and generative models. Here’s a breakdown of the key differences between RAG and traditional QA systems:   1. Static Knowledge vs. Dynamic Knowledge Traditional QA Systems: Often rely on pre-trained models that use static knowledge.

What is DPR, and how is it used in RAG?

  DPR stands for Dense Passage Retrieval, a cutting-edge method for retrieving relevant documents based on their semantic content. It is a deep learning-based retrieval model introduced by Facebook AI and designed to improve the accuracy and efficiency of information retrieval tasks.   How Does DPR Work? DPR employs a dual-encoder architecture with two main

What is Negative Sampling in RAG?

Negative sampling is a crucial technique in retriever training, helping models learn to distinguish between relevant and irrelevant documents. There are two key components of RAG: Retriever: Fetches relevant documents or data. Generator: Generates the output using the retrieved information. Negative sampling is a critical technique in training retrievers, particularly dense retrievers like DPR (Dense
