Melayu BERT

Melayu BERT is a masked language model based on BERT. It was trained on the OSCAR dataset, specifically the unshuffled_original_ms subset. The model used was English BERT model and fine-tuned on the Malaysian dataset. The model achieved a perplexity of 9.46 on a 20% validation dataset. Many of the techniques used are based on a Hugging Face tutorial notebook written by Sylvain Gugger, and fine-tuning tutorial notebook written by Pierre Guillou. The model is available both for PyTorch and TensorFlow use.

How to Use

As Masked Language Model

from transformers import pipeline
pretrained_name = "StevenLimcorn/MelayuBERT"
fill_mask = pipeline(
    "fill-mask",
    model=pretrained_name,
    tokenizer=pretrained_name
)
fill_mask("Saya [MASK] makan nasi hari ini.")

Import Tokenizer and Model

from transformers import AutoTokenizer, AutoModelForMaskedLM
  
tokenizer = AutoTokenizer.from_pretrained("StevenLimcorn/MelayuBERT")

model = AutoModelForMaskedLM.from_pretrained("StevenLimcorn/MelayuBERT")
