When is BERT Multilingual? Isolating Crucial Ingredients for Cross-lingual Transfer

1 code implementation27 Oct 2021 Ameet Deshpande, Partha Talukdar, Karthik Narasimhan

While recent work on multilingual language models has demonstrated their capacity for cross-lingual zero-shot transfer on downstream tasks, there is a lack of consensus in the community as to what shared properties between languages enable such transfer.

no code implementations5 Jun 2021 Simran Khanuja, Melvin Johnson, Partha Talukdar

Pre-trained multilingual language models (LMs) have achieved state-of-the-art results in cross-lingual transfer, but they often lead to an inequitable representation of languages due to limited capacity, skewed pre-training data, and sub-optimal vocabularies.
