## 🎯 What it does
Binary classifier to determine whether a given Persian social media text is related to a **traffic crash** or not.

## ⚙️ Fine-tuning
- **Base Model:** `bert-base-multilingual-cased`
- **Data:** Proprietary Persian social media crash dataset (Damavand County, Iran)

## 📊 Performance
| Task | Metric | Score |
|------|--------|-------|
| Crash Detection (Binary) | Accuracy | **91.1%** |

## 🚀 Quick Start
```python
from transformers import AutoModelForSequenceClassification, AutoTokenizer

model = AutoModelForSequenceClassification.from_pretrained("crash-information-extraction/BERT-Crash-nonCrash-Classification")
tokenizer = AutoTokenizer.from_pretrained("crash-information-extraction/BERT-Crash-nonCrash-Classification")

text = "تصادف در خیابان آزادی ۲ کشته داشت"
inputs = tokenizer(text, return_tensors="pt")
outputs = model(**inputs)
predicted_class = outputs.logits.argmax().item()
