## Sundanese GPT-2 Base Emotion Classifier |
|
|
|
Sundanese GPT-2 Base Emotion Classifier is an emotion-text-classification model based on the [OpenAI GPT-2](https://cdn.openai.com/better-language-models/language_models_are_unsupervised_multitask_learners.pdf) model. The model was originally the pre-trained [Sundanese GPT-2 Base](https://hf.co/w11wo/sundanese-gpt2-base) model, which is then fine-tuned on the [Sundanese Twitter dataset](https://github.com/virgantara/sundanese-twitter-dataset), consisting of Sundanese tweets. |
|
|
|
10% of the dataset is kept for evaluation purposes. After training, the model achieved an evaluation accuracy of 94.84% and F1-macro of 94.75%. |
|
|
|
Hugging Face's `Trainer` class from the [Transformers](https://huggingface.co/transformers) library was used to train the model. PyTorch was used as the backend framework during training, but the model remains compatible with other frameworks nonetheless. |

## How to Use |
|
|
|
### As Text Classifier |
|
|
|
```python |
|
from transformers import pipeline |
|
|
|
pretrained_name = "sundanese-gpt2-base-emotion-classifier" |
|
|
|
nlp = pipeline( |
|
"sentiment-analysis", |
|
model=pretrained_name, |
|
tokenizer=pretrained_name |
|
) |
|
|
|
nlp("Wah, éta gélo, keren pisan!") |
|
``` |
|
|
|
## Disclaimer |
|
|
|
Do consider the biases which come from both the pre-trained RoBERTa model and the Sundanese Twitter dataset 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.}, |
