New LIMIT method aligns pathology reports with tissue visuals
Researchers have developed a new method called Locked Image Multiple Instance PreTraining (LIMIT) to better align text from pathology reports with visual features from tissue samples. This approach freezes the vision en…

pgvector HNSW filtering bug causes RAG systems to return zero results
A developer encountered a critical issue with retrieval-augmented generation (RAG) systems using the pgvector extension in PostgreSQL. The problem stems from how pgvector's Hierarchical Navigable Small World (HNSW) inde…

New research shows multivectors offer exponential advantage in information retrieval
A new paper introduces the concept of "multivectors" for information retrieval, demonstrating an exponential separation in expressive power between single-vector and multi-vector embeddings. The research, which builds o…

New method extracts BM25-ready sparse features from dense retrieval models
Researchers have introduced a new method called Latent Terms, which demonstrates that dense retrieval models can be decomposed into sparse features suitable for traditional BM25 scoring. This technique, applied to froze…
