LEMUR and Mean Centering for Late-Interaction Retrieval in txtai reacted to davidmezzetti's post with 🔥 about 24 hours ago
Exciting addition coming with the next txtai release: LEMUR for ColBERT-style Late-Interaction Retrieval! 🎉
Contributor @Morgan-coded introduced LEMUR to txtai, making it, as far as we know, the first framework to incorporate LEMUR for late-interaction retrieval using standard, fixed-vector indexes.
Key benefits:
🚀 Significant boost: 49–62% higher NDCG@10 than 2,048-dimensional MUVERA
💾 5x less storage: 2,048 dimensions vs. MUVERA’s default 10,240
📐 Better geometry: Optional batch mean centering addresses anisotropy in token embeddings
A promising step toward making ColBERT-style retrieval more practical with conventional vector search.
