Hybrid Training Batch Ratios and Zero-Shot Retrieval Accuracy Across Low- and High-Resource Language Families on 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: How does varying the monolingual-to-cross-lingual batch ratio in hybrid training affect zero-shot retrieval accuracy on BEIR subsets for low-resource language families compared to high-resource ones?
