Scaling Language Count in Hybrid Batch Training for Cross-Lingual and Multilingual 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 scaling the number of languages in the hybrid batch training framework affect the trade-off between cross-lingual and multilingual retrieval performance, and what is the optimal batch size for balancing accuracy and efficiency?
