Curated web-derived text pairs with consistency filtering, trained a shared mean-pooled encoder using contrastive learning and query/passage prefixes, and optionally fine-tuned with labeled data and teacher distillation.
Scientific scope
Curated web-derived text pairs with consistency filtering, trained a shared mean-pooled encoder using contrastive learning and query/passage prefixes, and optionally fine-tuned with labeled data and teacher distillation. Unlabeled-pair pretraining and supervised fine-tuning are separate evidence settings. Consistency filtering uses a previously trained model and is not an unbiased quality oracle. Benchmark comparisons are source-version snapshots, not current leaderboard or universal domain-transfer guarantees.
Evidence
The linked original sources describe the stated contribution and its evidence limits. WRS has not independently rerun the experiments or certified a proof.
