Title: OPERA: Online Data Pruning for Efficient Retrieval Model Adaptation
Abstract:
arXiv:2603.17205v2 Announce Type: replace-cross Abstract: Domain-specific finetuning is essential for dense retrievers, yet not all training pairs contribute equally to the learning process. We introduce OPERA, a data pruning framework that exploits this heterogeneity to improve both the effectiveness and efficiency of retrieval model adaptation. We first investigate static pruning (SP), which retains only high-similarity query-document pairs, revealing an intrinsic quality-coverage tradeoff: ra
