Synergistic Hybrid Batch Training for Cross-Lingual Retrieval Robustness on Low-Resource Language Pairs in BEIR

Information retrieval across different languages is an increasingly important challenge in natural language processing. Recent approaches based on multilingual pre-trained language models have achieved remarkable success, yet they often optimize for either monolingual, cross-lingual, or multilingual retrieval performance at the expense of others. This paper proposes a novel hybrid batch training strategy to simultaneously improve zero-shot retrieval performance across monolingual, cross-lingual, and multilingual settings while mitigating language bias. The approach fine-tunes multilingual lang

Research goal: Does the synergistic hybrid batch training strategy improve cross-lingual retrieval robustness on low-resource language pairs within the BEIR benchmark relative to monolingual-only optimization?
