Scaling Multimodal Intermediate Datasets for Robust Zero-Shot Cross-Lingual Transfer in Language Understanding

Multilingual BERT (mBERT), a language model pre-trained on large multilingual corpora, has impressive zero-shot cross-lingual transfer capabilities and performs surprisingly well on zero-shot POS tagging and Named Entity Recognition (NER), as well as on cross-lingual model transfer. At present, the mainstream methods to solve the cross-lingual downstream tasks are always using the last transformer layer's output of mBERT as the representation of linguistic information. In this work, we explore the complementary property of lower layers to the last transformer layer of mBERT. A feature aggregat

Research goal: Does scaling the size of multimodal intermediate datasets improve robustness in zero-shot cross-lingual transfer for language understanding tasks relative to unimodal pretraining?
