## Model description |
|
This model is a finetune of roberta-base to detect suicidal tendencies in a given text. |
|
|
|
## Training and evaluation data |
|
- The dataset is sourced from Reddit and is available on [Kaggle](https://www.kaggle.com/datasets/nikhileswarkomati/suicide-watch). |
|
- The dataset contains text with binary labels for suicide or non-suicide. |
|
- The dataset was cleaned, and following steps were applied |
|
- Converted to lowercase |
|
- Removed numbers and special characters. |
|
- Removed URLs, Emojis and accented characters. |
|
- Removed any word contractions. |
|
- Remove any extra white spaces and any extra spaces after a single space. |
|
- Removed any consecutive characters repeated more than 3 times. |
|
- Tokenised the text, then lemmatized it and then removed the stopwords (excluding not). |
|
- The cleaned dataset can be found [here](https://huggingface.co/datasets/vibhorag101/suicide_prediction_dataset_phr) |
|
- The evaluation set had ~23000 samples, while the training set had ~186k samples, i.e. a 80:10:10 (train:test:val) split. |
|
|
|
## Training procedure |
|
- The model was trained on an RTXA5000 GPU. |
|
|
|
### Training hyperparameters |
|

|
- seed: 42 |
|
- optimizer: Adam with betas=(0.9,0.999) and epsilon=1e-08 |
|
- lr_scheduler_type: linear |
|
- num_epochs: 3 |
