# vibhorag101/roberta-base-suicide-prediction-phr-v2 |
|
|
|
This model is a fine-tuned version of [roberta-base](https://huggingface.co/roberta-base) on [Suicide Prediction Dataset](https://huggingface.co/datasets/vibhorag101/phr_suicide_prediction_dataset_clean_light), sourced from Reddit. |
|
It achieves the following results on the evaluation set: |
|
- Loss: 0.0553 |
|
- Accuracy: 0.9869 |
|
- Recall: 0.9846 |
|
- Precision: 0.9904 |

|
## 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 minimally, as BERT depends on contextually sensitive information, which can worsely effect its performance. |
|
- Removed numbers |
|
- Removed URLs, Emojis, and accented characters. |
|
- Remove any extra white spaces and any extra spaces after a single space. |
|
- Removed any consecutive characters repeated more than 3 times. |
|
- The rows with more than 512 BERT Tokens were removed, as they exceeded BERT's max token. |
|
- The cleaned dataset can be found [here](https://huggingface.co/datasets/vibhorag101/phr_suicide_prediction_dataset_clean_light) |
|
- The evaluation set had ~33k samples, while the training set had ~153k samples, i.e., a 70:15:15 (train:test:val) split. |
|
|
|
