Performance of Hybrid Batch Training on XLM-R Benchmark for Retrieval Accuracy and Generalization in Low-Resource Languages

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 perform on the XLM-R benchmark compared to specialized monolingual and cross-lingual training in terms of retrieval accuracy and generalization across low-resource languages?
