# ViSoBERT‑HSD: Hate Speech Detection for Vietnamese Text

Fine‑tuned from [`uitnlp/visobert`](https://huggingface.co/uitnlp/visobert) on the **VN‑HSD** unified Vietnamese hate‐speech dataset, combining ViHSD, ViCTSD, and ViHOS.

## Model Details

* **Base Model**: [`uitnlp/visobert`](https://huggingface.co/uitnlp/visobert)
* **Dataset**: VN‑HSD (ViSoLex‑HSD unified hate speech corpus)
* **Fine‑tuning**: HuggingFace Transformers

### Hyperparameters

* Batch size: `32`
* Learning rate: `3e-5`
* Epochs: `100`
* Max sequence length: `256`

## Results

* **Accuracy**: `<INSERT_ACCURACY>`
* **F1 Score**: `<INSERT_F1_SCORE>`

## Usage

```python
from transformers import AutoTokenizer, AutoModelForSequenceClassification

tokenizer = AutoTokenizer.from_pretrained("visolex/visobert-hsd")
model = AutoModelForSequenceClassification.from_pretrained("visolex/visobert-hsd")

text = "Hắn ta thật kinh tởm!"
inputs = tokenizer(text, return_tensors="pt", truncation=True, max_length=256)
logits = model(**inputs).logits
pred = logits.argmax(dim=-1).item()
label_map = {0: "CLEAN", 1: "OFFENSIVE", 2: "HATE"}
print(f"Predicted label: {label_map[pred]}")
```
