RAG Rerank: the Highest-Leverage Upgrade to Your Retrieval Pipeline
A new technique called RAG Rerank significantly improves the accuracy of retrieval-augmented generation (RAG) systems by adding a reranking step. Standard RAG retrieves documents based on vector similarity, which can lead to irrelevant documents being prioritized. RAG Rerank uses a cross-encoder model to re-evaluate the relevance of a shortlisted set of documents, ensuring that the most pertinent information is passed to the language model. This approach enhances accuracy at the cost of slightly increased latency and expense, making it particularly valuable for applications where incorrect answers are costly. AI
