Hybrid Batch Training for Robust Zero-Shot Cross-Lingual Retrieval Across Typological Distances on MIRACL

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: Does the proposed hybrid batch training approach improve robustness against typological distance in zero-shot cross-lingual retrieval on MIRACL compared to standard multilingual fine-tuning?
