Degradation of Monolingual Retrieval Performance on English BEIR Datasets via Hybrid Batch Training Strategies

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: To what extent does the proposed hybrid batch training strategy degrade monolingual retrieval performance on English BEIR datasets compared to models trained exclusively on monolingual corpora?
