Margin Parameter Effects on Cross-Domain Dense Retrieval Accuracy in NQ

This report synthesises findings from 16 peer-reviewed papers addressing the following research question: How does varying the margin parameter in contrastive learning objectives impact retrieval accuracy in cross-domain dense retrievers on NQ compared to models trained solely with pairwise ranking losses. 9 claims were extracted from source literature; 9 were independently verified against retrieved documents. An automated multi-reviewer quality assessment produced a score of 7.6/10. This report is a machine-generated literature synthesis and does not constitute original research.
