Hybrid Batch Training Dynamics in Monolingual and Cross-Lingual Retrieval Performance

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 ratio of monolingual, cross-lingual, and multilingual examples in hybrid batch training influence the trade-off between monolingual retrieval accuracy and cross-lingual retrieval performance on the ML-Doc and FEVER benchmarks?
