HyDE (Hypothetical Document Embedding)

This code implements a Hypothetical Document Embedding (HyDE) system for document retrieval. HyDE is an innovative approach that transforms query questions into hypothetical documents containing the answer, aiming to bridge the gap between query and document distributions in vector space.

Traditional retrieval methods often struggle with the semantic gap between short queries and longer, more detailed documents. HyDE addresses this by expanding the query into a full hypothetical document, potentially improving retrieval relevance by making the query representation more similar to the document representations in the vector space.
