Model Size and Zero-Shot Cross-Lingual Retrieval Performance in Hybrid Batch-Trained Models

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 effect of model size (e.g., 7B vs. 13B vs. 30B parameters) on the zero-shot cross-lingual retrieval performance of hybrid batch-trained models compared to standard multilingual fine-tuning on BEIR?
