Back-Translation Integration in Hybrid Batch Training for Zero-Shot XTYLE Retrieval Performance

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: How does the inclusion of back-translated examples in the hybrid batch training strategy affect zero-shot retrieval performance on the XTYLE benchmark compared to using only native monolingual examples, as measured by MRR@20?
