AWhat changed
Mined hard negatives from an approximate nearest-neighbor index of the corpus while a parallel inferencer periodically re-encoded documents and refreshed the index from newer training checkpoints.
Scientific scope
Mined hard negatives from an approximate nearest-neighbor index of the corpus while a parallel inferencer periodically re-encoded documents and refreshed the index from newer training checkpoints. Asynchronous refresh permits stale negatives and incurs re-encoding/index costs; it does not exactly eliminate every train-test distribution gap. Uses inherited encoders, nearest-neighbor search and contrastive losses. Source speedups depend on baselines and workload, not unconditional100x acceleration.
Evidence
The linked original sources describe the stated contribution and its evidence limits. WRS has not independently rerun the experiments or certified a proof.
