Optimal Transport-Based Alignment for Mitigating Resource Disparities in Scaled Multimodal Retrieval on Flickr30k-Entities

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: Does optimal transport-based alignment reduce the performance gap between high and low-resource languages in multimodal retrieval tasks when scaling to larger multilingual pre-trained models on Flickr30k-Entities?
