Hybrid Batch Training vs. Contrastive Learning for Zero-Shot Cross-Lingual 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: How does the hybrid batch training strategy compare to traditional contrastive learning methods in terms of zero-shot cross-lingual retrieval performance on benchmark datasets like MTEB or Xtreme-R?
