Scaling Hybrid Batch Training Across Languages: Monolingual and Cross-Lingual Trade-offs on the mQA Benchmark

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 hybrid batch training strategy scale with increasing numbers of languages in the training set, and what is the trade-off between monolingual and cross-lingual performance on the mQA benchmark?
