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: Can the proposed hybrid batch training strategy improve zero-shot cross-lingual retrieval performance on low-resource languages in NLP benchmarks like TyDiQA or MLQA compared to monolingual or cross-lingual-only training?
