Impact of Cross-Lingual Batch Ratio on Zero-Shot Retrieval Accuracy in XTREME Benchmark

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 varying the cross-lingual batch ratio in hybrid training impact zero-shot retrieval accuracy on the XTREME benchmark for low-resource language pairs?
