Hybrid Batch Training Ratios in Multilingual T5 for Zero-Shot Cross-Lingual Performance

Multilingual pre-trained models have achieved remarkable performance on cross-lingual transfer learning. Some multilingual models such as mBERT, have been pre-trained on unlabeled corpora, therefore the embeddings of different languages in the models may not be aligned very well. In this paper, we aim to improve the zero-shot cross-lingual transfer performance by proposing a pre-training task named Word-Exchange Aligning Model (WEAM), which uses the statistical alignment information as the prior knowledge to guide cross-lingual word prediction. We evaluate our model on multilingual machine rea

Research goal: How does varying the ratio of English to low-resource languages in hybrid batch training affect the zero-shot cross-lingual performance of multilingual T5 models on XNLI, compared to PAWS-X and MLQA benchmarks?
