Zero-shot Document Retrieval with Hybrid Pseudo-document Retriever

ICASSP 2025accepted

The zero-shot retrieval task aims to retrieve the most relevant documents to a user’s query without relevance labels. Current approaches expand input queries by generating pseudo-documents with large language models (LLMs) and perform document retrieval based on the expanded queries. However, their…
