Impact of Batch Composition Ratio on Monolingual-Cross-Lingual Retrieval Trade-Off in Hybrid Training

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 batch composition ratio in the hybrid training strategy on the trade-off between monolingual and cross-lingual retrieval performance on the MILLIQA and MLIR-100 benchmarks?
