Multilingual Contrastive Learning in Hybrid Batch Training for Zero-Shot Cross-Lingual Retrieval

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 incorporating multilingual self-supervised contrastive learning into the hybrid batch training strategy on zero-shot cross-lingual retrieval performance as measured by F1 scores on the MLQA benchmark?
