Javanese RoBERTa Small IMDB

Javanese RoBERTa Small IMDB is a masked language model based on the RoBERTa model. It was trained on Javanese IMDB movie reviews.

The model was originally the pretrained Javanese RoBERTa Small model and is later fine-tuned on the Javanese IMDB movie review dataset. It achieved a perplexity of 20.83 on the validation dataset. Many of the techniques used are based on a Hugging Face tutorial notebook written by Sylvain Gugger.

Hugging Face's Trainer class from the Transformers library was used to train the model. PyTorch was used as the backend framework during training, but the model remains compatible with TensorFlow nonetheless.

Evaluation Results

The model was trained for 5 epochs and the following is the final result once the training ended.

How to Use

As Masked Language Model

from transformers import pipeline

pretrained_name = "w11wo/javanese-roberta-small-imdb"

fill_mask = pipeline(
    "fill-mask",
    model=pretrained_name,
    tokenizer=pretrained_name
)

fill_mask("Aku mangan sate ing <mask> bareng konco-konco")

Feature Extraction in PyTorch

from transformers import RobertaModel, RobertaTokenizerFast

pretrained_name = "w11wo/javanese-roberta-small-imdb"
model = RobertaModel.from_pretrained(pretrained_name)
tokenizer = RobertaTokenizerFast.from_pretrained(pretrained_name)

prompt = "Indonesia minangka negara gedhe."
encoded_input = tokenizer(prompt, return_tensors='pt')
output = model(**encoded_input)

Disclaimer

Do consider the biases which came from the IMDB review that may be carried over into the results of this model.
