distilroberta-base-finetuned-fake-news-detection
This model is a fine-tuned version of distilroberta-base on this Fake News Detection Dataset, which has been constructed by combining multiple Fake News datasets from Kaggle.
This is the classification report after training for 3 full epochs:
| Precision | Recall | F-1 Score | Support | |
|---|---|---|---|---|
| Not Hate Speech (0) | 0.99 | 0.99 | 0.99 | 4335 |
| Hate Speech (1) | 0.99 | 0.99 | 00.99 | 3782 |
| accuracy | 00.99 | 8117 | ||
| macro avg | 0.99 | 0.99 | 0.99 | 8117 |
| weighted avg | 0.99 | 0.99 | 0.99 | 8117 |
Training and evaluation data
All of the process to train this model is available in this repository. The dataset has been split into 24,353 examples for training & 8,117 examples for validation & testing each.
Training hyperparameters
The following hyperparameters were used during training:
- learning_rate: 5e-05
- train_batch_size: 32
- eval_batch_size: 32
- optimizer: default AdamW Optimizer
- num_epochs: 3
- warmup_steps: 500
- weight_decay: 0.01
- random seed: 42
I also trained for 3 full epochs on Colab's Tesla P100-PCIE-16GB GPU.
