Impact of Hybrid Batch Training on Zero-Shot Retrieval Accuracy for Low-Resource Languages in MIRACL with XQuAD Fine-Tuning

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 hybrid batch training impact zero-shot retrieval accuracy on the MIRACL benchmark for low-resource languages when integrated with multilingual instruction fine-tuning on XQuAD?
