## Sundanese RoBERTa Base
|
16 |
+
|
17 |
+
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/).
|
18 |
+
|
19 |
+
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%.
|
20 |
+
|
21 |
+
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
|
38 |
+
|
39 |
+
### As Masked Language Model
|
40 |
+
|
41 |
+
```python
|
42 |
+
from transformers import pipeline
|
43 |
+
|
44 |
+
pretrained_name = "w11wo/sundanese-roberta-base"
|
45 |
+
|
46 |
+
fill_mask = pipeline(
|
47 |
+
"fill-mask",
|
48 |
+
model=pretrained_name,
|
49 |
+
tokenizer=pretrained_name
|
50 |
+
)
|
51 |
+
|
52 |
+
fill_mask("Budi nuju <mask> di sakola.")
|
53 |
+
```
|
54 |
+
|
55 |
+
### Feature Extraction in PyTorch
|
56 |
+
|
57 |
+
```python
|
58 |
+
from transformers import RobertaModel, RobertaTokenizerFast
|
59 |
+
|
60 |
+
pretrained_name = "w11wo/sundanese-roberta-base"
|
61 |
+
model = RobertaModel.from_pretrained(pretrained_name)
|
62 |
+
tokenizer = RobertaTokenizerFast.from_pretrained(pretrained_name)
|
63 |
+
|
64 |
+
prompt = "Budi nuju diajar di sakola."
|
65 |
+
encoded_input = tokenizer(prompt, return_tensors='pt')
|
66 |
+
output = model(**encoded_input)
|
67 |
+
```
|
68 |
+
|
69 |
+
## Disclaimer
|
70 |
+
|
71 |
+
Do consider the biases which came from all four datasets that may be carried over into the results of this model.
