# 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
- F1: 0.9875
## 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.
## Training procedure
- The model was trained on an RTXA5000 GPU.
