# Global Financial Transaction Classifier

A state-of-the-art DistilBERT-based model for classifying financial transactions across 10 categories and 5 countries. This model is trained on 4.5M+ financial transactions from the [Hugging Face dataset](https://huggingface.co/datasets/mitulshah/transaction-categorization).

## 🏷️ Categories

The model can classify transactions into 10 comprehensive categories:

1. **Food & Dining** - Restaurants, groceries, fast food, coffee shops, food delivery
2. **Transportation** - Gas, rideshare, airlines, public transport, car rental  
3. **Shopping & Retail** - Online shopping, electronics, retail, fashion, home & garden
4. **Entertainment & Recreation** - Streaming, gaming, movies, music, sports
5. **Healthcare & Medical** - Medical, pharmacy, dental, vision, fitness
6. **Utilities & Services** - Electricity, water, gas, internet & phone, cable
7. **Financial Services** - Banking, insurance, credit cards, investments, taxes
8. **Income** - Salary, freelance, business, investments, government benefits
9. **Government & Legal** - Taxes, licenses, legal services, government fees
10. **Charity & Donations** - Charitable, religious, community, political donations

## 🌍 Geographic Coverage

- **USA** (USD) - McDonald's, Uber, Amazon, Netflix
- **UK** (GBP) - Tesco, Shell, ASDA, BBC iPlayer  
- **Canada** (CAD) - Tim Hortons, Petro-Canada, Loblaws
- **Australia** (AUD) - Coles, Woolworths, Bunnings, Telstra
- **India** (INR) - Big Bazaar, Ola, Flipkart, Zomato

## 🚀 Quick Start

### Installation

```bash
pip install torch transformers datasets scikit-learn pandas numpy
```

### Basic Usage

```python
from inference import FinancialTransactionClassifier

# Initialize the classifier
classifier = FinancialTransactionClassifier()

# Predict a single transaction
result = classifier.predict("McDonald's #1234")
print(f"Category: {result['predicted_category']}")
print(f"Confidence: {result['confidence']:.3f}")

# Predict multiple transactions
transactions = [
    "Uber Ride to Airport",
    "Amazon Purchase - Electronics", 
    "Netflix Monthly Subscription"
]

results = classifier.predict_batch(transactions)
for transaction, result in zip(transactions, results):
    print(f"{transaction} -> {result['predicted_category']}")
```

### Advanced Usage

```python
# Get top-3 predictions
top_predictions = classifier.get_top_k_predictions("Shell Gas Station", k=3)
for i, pred in enumerate(top_predictions, 1):
    print(f"{i}. {pred['category']}: {pred['probability']:.3f}")
```
