Hybrid Batch Training Effects on Zero-Shot Domain Transfer in Out-of-Distribution BEIR Datasets

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: How does the hybrid batch training strategy proposed in the paper affect zero-shot domain transfer performance specifically on out-of-distribution BEIR datasets like SciFact or Climate-FEVER compared to traditional monolingual or cross-lingual training?
