Sundanese RoBERTa Base
Sundanese RoBERTa Base is a masked language model based on the RoBERTa model. It was trained on four datasets: OSCAR's unshuffled_deduplicated_su subset, the Sundanese mC4 subset, the Sundanese CC100 subset, and Sundanese Wikipedia.
10% of the dataset is kept for evaluation purposes. The model was trained from scratch and achieved an evaluation loss of 1.952 and an evaluation accuracy of 63.98%.
This model was trained using HuggingFace's Flax framework. All necessary scripts used for training could be found in the Files and versions tab, as well as the Training metrics logged via Tensorboard.

How to Use
As Masked Language Model
from transformers import pipeline
pretrained_name = "w11wo/sundanese-roberta-base"
fill_mask = pipeline(
"fill-mask",
model=pretrained_name,
tokenizer=pretrained_name
)
fill_mask("Budi nuju <mask> di sakola.")
Feature Extraction in PyTorch
from transformers import RobertaModel, RobertaTokenizerFast
pretrained_name = "w11wo/sundanese-roberta-base"
model = RobertaModel.from_pretrained(pretrained_name)
tokenizer = RobertaTokenizerFast.from_pretrained(pretrained_name)
prompt = "Budi nuju diajar di sakola."
encoded_input = tokenizer(prompt, return_tensors='pt')
output = model(**encoded_input)
Disclaimer
Do consider the biases which came from all four datasets that may be carried over into the results of this model.

abstract = {The Sundanese language has over 32 million speakers worldwide, but the language has reaped little to no benefits from the recent advances in natural language understanding. Like other low-resource languages, the only alternative is to fine-tune existing multilingual models. In this paper, we pre-trained three monolingual Transformer-based language models on Sundanese data. When evaluated on a downstream text classification task, we found that most of our monolingual models outperformed larger multilingual models despite the smaller overall pre-training data. In the subsequent analyses, our models benefited strongly from the Sundanese pre-training corpus size and do not exhibit socially biased behavior. We released our models for other researchers and practitioners to use.},
