Optimal Transport Distillation for Robust Cross-Lingual Retrieval Against Code-Switching in Low-Resource Queries

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: What is the impact of optimal transport distillation on the robustness of cross-lingual retrieval models against code-switching phenomena in low-resource language queries within the MTOP benchmark?
