Hybrid Batch Training for Robust Cross-Lingual Retrieval Against Synthetic Noise

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: To what extent does the proposed hybrid batch training strategy improve robustness against synthetic noise injections in cross-lingual retrieval benchmarks compared to standard multilingual fine-tuning?
