Synergistic Optimization of Monolingual and Cross-Lingual Objectives in Hybrid Batch Training for 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: Does the synergistic optimization of monolingual and cross-lingual objectives in hybrid batch training degrade multilingual retrieval performance on XTREME-R relative to dedicated multilingual contrastive baselines?
