Multilingual Retrieval vs. Monolingual Reasoning Trade-offs in Mixed-Language Batch Training

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 trade-off between multilingual retrieval performance and monolingual reasoning capabilities in large language models trained with mixed-language batch strategies?
