Hybrid Batch Training for Multilingual Reasoning and BEIR 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: What is the impact of the hybrid batch training strategy on multilingual reasoning tasks (e.g., MMLU) when evaluated in zero-shot cross-lingual settings, and does it correlate with improvements in BEIR retrieval performance?
