Hybrid Batch Training Data Ratios for Zero-Shot Retrieval in Typologically Distant BEIR Language Pairs

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: What is the effect of varying the ratio of monolingual, cross-lingual, and multilingual data in hybrid batch training on zero-shot retrieval performance in the BEIR benchmark for typologically distant language pairs?
