Model
| Name: | SLIM++ |
|---|---|
| Description: | SLIM maps each contextualized token vector to a sparse, high-dimensional lexical space before performing late interaction between sparse token embeddings. It employs a two-stage retrieval architecture that includes inverted index retrieval followed by a score refinement module to approximate the sparsified late interaction, which is fully compatible with off-the-shelf lexical search libraries such as Lucene. SLIM++ enhances SLIM with cross-encoder distillation and hard negative mining. |
