Scaling Intermediate Multimodal Tasks for Zero-Shot Cross-Lingual Transfer Performance

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: What is the effect of scaling the number of intermediate multimodal tasks on zero-shot cross-lingual transfer performance, evaluated using F1 scores on MMMU's multilingual subsets?
