Training Corpus Size and Out-of-Distribution Generalization in Dense Retrievers on BEIR

This report synthesises findings from 15 peer-reviewed papers addressing the following research question: What is the effect of varying the size of the training corpus on the OOD generalization capabilities of dense retrievers when evaluated on BEIR's heterogeneous datasets. 7 claims were extracted from source literature; 7 were independently verified against retrieved documents. An automated multi-reviewer quality assessment produced a score of 8.8/10. This report is a machine-generated literature synthesis and does not constitute original research.
