Impact of Hybrid Batch Size Scaling on Monolingual vs. Cross-Lingual Retrieval Trade-Off in Out-of-Domain Zero-Shot Tasks

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 scaling the hybrid batch size on the trade-off between monolingual and cross-lingual retrieval performance in out-of-domain zero-shot tasks using BEIR or NQ benchmarks?
