Using Optimal Transport as Alignment Objective for fine-tuning Multilingual Contextualized Embeddings [article]

Sawsan Alqahtani, Garima Lalwani, Yi Zhang, Salvatore Romeo, Saab Mansour
2021 arXiv   pre-print
This approach does not require word-alignment pairs prior to fine-tuning that may lead to sub-optimal matching and instead learns the word alignments within context in an unsupervised manner.  ...  In this work, we propose using Optimal Transport (OT) as an alignment objective during fine-tuning to further improve multilingual contextualized representations for downstream cross-lingual transfer.  ...  This method learns word alignments while fine-tuning the pre-trained representations in an end-to-end fashion.  ...
