Optimal Transport Distillation Effects on Zero-Shot Retrieval Recall for Low-Resource Languages in MIRACL

Benefiting from transformer-based pre-trained language models, neural ranking models have made significant progress. More recently, the advent of multilingual pre-trained language models provides great support for designing neural cross-lingual retrieval models. However, due to unbalanced pre-training data in different languages, multilingual language models have already shown a performance gap between high and low-resource languages in many downstream tasks. And cross-lingual retrieval models built on such pre-trained models can inherit language bias, leading to suboptimal result for low-reso

Research goal: How does optimal transport distillation impact zero-shot retrieval recall on MIRACL for low-resource languages excluded from code-switched training compared to standard knowledge distillation?
