**"Ratio Variation in Hybrid Batch Training for mBERT Zero-Shot Multilingual 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 varying the ratio of monolingual to cross-lingual training samples in hybrid batch training on the zero-shot multilingual retrieval performance of mBERT variants, as measured by F1 scores on the XQuAD benchmark?
