# dv-muril

This is an experiment in transfer learning, to insert Dhivehi word and
word-piece tokens into Google's MuRIL model.

This BERT-based model currently performs better than dv-wave ELECTRA on
the Maldivian News Classification task https://github.com/Sofwath/DhivehiDatasets

## Training

- Start with MuRIL (similar to mBERT) with no Thaana vocabulary
- Based on PanLex dictionaries, attach 1,100 Dhivehi words to Malayalam or English embeddings
- Add remaining words and word-pieces from dv-wave to vocab.txt
- Continue BERT pretraining on a TPU
