## Sundanese RoBERTa Base |
|
|
|
Sundanese RoBERTa Base is a masked language model based on the [RoBERTa](https://arxiv.org/abs/1907.11692) model. It was trained on four datasets: [OSCAR](https://hf.co/datasets/oscar)'s `unshuffled_deduplicated_su` subset, the Sundanese [mC4](https://hf.co/datasets/mc4) subset, the Sundanese [CC100](https://hf.co/datasets/cc100) subset, and Sundanese [Wikipedia](https://su.wikipedia.org/). |
|
|
|
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](https://hf.co/w11wo/sundanese-roberta-base/tree/main) tab, as well as the [Training metrics](https://hf.co/w11wo/sundanese-roberta-base/tensorboard) logged via Tensorboard. |

## How to Use |
|
|
|
### As Masked Language Model |
|
|
|
```python |
|
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 |
|
|
|
```python |
|
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.}, |
