## Fraud Detection Dataset
A production-grade, large-scale dataset containing 50 million transactions designed to serve both the beginner data scientist and the enterprise data engineer.
**What is inside:**
- 50 million rows of high-fidelity synthetic transaction data
- 19 carefully engineered fields covering core transaction data, velocity signals, geospatial context, device fingerprinting, and diagnostic fraud labels
- A realistic 2.5% fraud rate simulating the exact needle-in-a-haystack challenge faced by real fraud teams at major financial institutions
- Granular `fraud_type` labels enabling multi-class classification, not just binary detection
**File formats provided:**
- `sample_50rows.csv` — No gate. Inspect immediately.
- `fraud_detection_50M.parquet` — Full 50 million row file. No gate. Free access.
**Quick load example:**
```python
import pandas as pd
df = pd.read_parquet('fraud_detection_50M.parquet')
print(df.head())
```
