Comparative Analysis of Hybrid Batch Training Versus State-of-the-Art Multilingual Models on XLM-R BEIR Zero-Shot 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: How does the hybrid batch training strategy proposed in the paper compare to state-of-the-art multilingual models on the XLM-R BEIR benchmark in terms of zero-shot retrieval accuracy across high-resource and low-resource languages?
