Hybrid Batch Training Strategy for Enhanced Zero-Shot Multilingual Retrieval on the MTEB 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: Does the hybrid batch training strategy improve zero-shot retrieval performance on the MTEB benchmark compared to standard multilingual pre-trained models across diverse languages?
