# bcms-bertic-parlasent-bcs-bi

Binary text classification model based on [`classla/bcms-bertic`](https://huggingface.co/classla/bcms-bertic) and fine-tuned on the BCS Political Sentiment dataset.

This classifier classifies text into only two categories: Negative vs. Other. For the ternary classifier (Negative, Neutral, Positive) check [this model](https://huggingface.co/classla/bcms-bertic-parlasent-bcs-ter).


## Fine-tuning hyperparameters

Fine-tuning was performed with `simpletransformers`. Beforehand a brief sweep for the optimal number of epochs was performed and the presumed best value was 9. Other arguments were kept default.

```python

model_args = {
        "num_train_epochs": 9
        }
```

## Performance in comparison with ternary classifier

| model                                     | average macro F1 |
|-------------------------------------------|------------------|
| bcms-bertic-parlasent-bcs-ter             | 0.7941 ± 0.0101  |
| bcms-bertic-parlasent-bcs-bi (this model) | 0.8999 ± 0.012   |
