Multimodal Pre-training for Zero-Shot Cross-Lingual Retrieval on X-MNLI

This paper studies zero-shot cross-lingual transfer of vision-language models. Specifically, we focus on multilingual text-to-video search and propose a Transformer-based model that learns contextualized multilingual multimodal embeddings. Under a zero-shot setting, we empirically demonstrate that performance degrades significantly when we query the multilingual text-video model with non-English sentences. To address this problem, we introduce a multilingual multimodal pre-training strategy, and collect a new multilingual instructional video dataset (MultiHowTo100M) for pre-training. Experimen

Research goal: How does the incorporation of multimodal pre-training (vision + text) on code-switched data improve zero-shot cross-lingual retrieval performance on X-MNLI compared to text-only baselines, measured by accuracy and cross-lingual consistency?
