Reply to comment by koolaidman123 in [D] Difference between sparse and dense information retrieval by itsyourboiirow

ColBERT is both on the dense and the sparse leaderboard :^)

I would describe it as a (sparse?) collection of dense embeddings per query/document, so it's hard to classify it between the two (although I'm leaning more toward the dense categorization).

splade-v2 and sparta are exclusively on the sparse leaderboards, and they uses bert

the point is dispelling the notion that sparse retrieval somehow = no dl involved. it's conflating dense retrieval with neural retrieval
