Impact of Hybrid Training Batch Ratios on Zero-Shot Retrieval Across Typological Distances

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 varying the ratio of monolingual, cross-lingual, and multilingual batches in the hybrid training strategy on zero-shot retrieval performance across language pairs with different typological distances, as evaluated by normalized mean reciprocal rank (nMRR) on XM3600 test sets?
