  # dv-wave
  
  This is a second attempt at a Dhivehi language model trained with
  Google Research's [ELECTRA](https://github.com/google-research/electra).
  
  Tokenization and pre-training CoLab: https://colab.research.google.com/drive/1ZJ3tU9MwyWj6UtQ-8G7QJKTn-hG1uQ9v?usp=sharing
  
  Using SimpleTransformers to classify news https://colab.research.google.com/drive/1KnyQxRNWG_yVwms_x9MUAqFQVeMecTV7?usp=sharing
  
  V1: similar performance to mBERT on news classification task after finetuning for 3 epochs (52%)
  
  V2: fixed tokenizers ```do_lower_case=False``` and ```strip_accents=False``` to preserve vowel signs of Dhivehi
    dv-wave: 89% to mBERT: 52%
  
  ## Corpus
  
  Trained on @Sofwath's 307MB corpus of Dhivehi text: https://github.com/Sofwath/DhivehiDatasets - this repo also contains the news classification task CSV
  
  [OSCAR](https://oscar-corpus.com/) was considered but has not been added to pretraining; as of
  this writing their web crawl has 126MB of Dhivehi text (79MB deduped).
  
  ## Vocabulary
  
  Included as vocab.txt in the upload - vocab_size is 29874
