What is recorded here?
Learned vocabulary-space query/document expansion with log-saturated weights and explicit sparsity regularization; v2 changed aggregation to max pooling, evaluated document-only expansion and added teacher-distilled hard-negative training.
Source-linked catalogue note. A detailed explanatory guide has not yet been prepared for this entry.
Scientific scope
FLOPS regularization and sparse expansion build on prior work, not invented wholesale here. Efficiency proxies, index storage and actual latency are distinct; offline preprocessing remains. Original preprints contain placeholder conference/DOI fields, not valid publication receipts. BEIR subset evaluations are not full benchmark-wide dominance.
