A real-time financial transaction monitoring system that detects suspicious activities using machine learning.
- AI-Powered Analysis: Uses Isolation Forest algorithm for anomaly detection
- Real-time Monitoring: Live transaction analysis and scoring
- Risk Assessment: Automatic risk level classification (Low/Medium/High)
- 28-Dimensional Analysis: Examines V1-V28 features + transaction amount
- Vibrant Visual Interface: Dark theme with neon accents
- Live Statistics: Real-time anomaly counts and metrics
- Interactive Charts: Dynamic data visualization with Chart.js
- Color-coded Alerts: Immediate visual feedback for anomalies
- Responsive Design: Works seamlessly on all devices
- Human-in-the-Loop: Submit feedback on predictions
- Feedback Categories: False Positive, False Negative, Confirmed, Other
- History Tracking: Complete audit trail of all feedback
- n8n Integration: Automatically forwards feedback to webhooks
- Export Capabilities: JSON-based feedback logging
- Fast Predictions: Sub-second anomaly scoring
- Auto-retraining: On-demand model retraining API
- Health Monitoring: Built-in system status checks
- Scalable Architecture: Modular Flask backend

- Clone the repository
git clone https://github.com/yourusername/auditmate.git
cd auditmate
Create virtual environment
bash
python -m venv venv
source venv/bin/activate # On Windows: venv\Scripts\activate
Install dependencies
bash
pip install -r requirements.txt
Prepare your data
Place your transaction CSV file as Auditmate Transactions - Sheet1.csv in the project root
CSV should contain columns: TransactionID, v1-v28, Amount
Running the Application
Start the backend server
bash
python main.py
Access the dashboard
Open your browser and navigate to: http://localhost:5000/dashboard
API health check: http://localhost:5000/health
Optional: n8n Integration
Create a .env file for webhook automation:
env
N8N_WEBHOOK_URL=http://localhost:5678/webhook/feedback
