Monolingual-to-Cross-Lingual Batch Ratio Effects on Zero-Shot Retrieval Robustness in XQuAD Low-Resource Languages

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 monolingual-to-cross-lingual batch ratio impact the robustness of zero-shot retrieval on low-resource languages within the XQuAD benchmark?
