Zero-shot Cross-lingual Transfer Performance of XLM-R in Mixed-precision vs. Full-precision Training on XTREME-R

Pre-trained multilingual language encoders, such as multilingual BERT and XLM-R, show great potential for zero-shot cross-lingual transfer. However, these multilingual encoders do not precisely align words and phrases across languages. Especially, learning alignments in the multilingual embedding space usually requires sentence-level or word-level parallel corpora, which are expensive to be obtained for low-resource languages. An alternative is to make the multilingual encoders more robust; when fine-tuning the encoder using downstream task, we train the encoder to tolerate noise in the contex

Research goal: How does the zero-shot cross-lingual transfer performance on XTREME-R compare when using XLM-R in a mixed-precision training setting versus full-precision training, measured by F1 score and inference throughput?
