MHDC MentalBERT

Fine-tuned from mental/mental-bert-base-uncased for 10-way classification of mental-health conditions and cyberbullying in social-media posts.

This repository is the retrained model: config, tokenizer, and weights from one fine-tuning run. It replaces an earlier upload that was only a converted checkpoint.

Held-out test set, 6,000 imbalanced posts: accuracy 0.919, macro F1 0.769.
