CAREN - AI-Powered Financial Crime Detection

CAREN (Credit Analysis & Risk Evaluation Network) is a next-generation AI-powered transaction monitoring system designed to detect financial crimes in real-time while dramatically reducing false positives that overwhelm compliance teams. The system employs an ensemble of five machine learning models—XGBoost, Random Forest, Logistic Regression, K-Nearest Neighbors, and AdaBoost Decision Tree—trained on anonymized PCA-transformed transaction features (V1-V28). This architecture achieves 99.94% accuracy, 94.12% precision, and 81.63% recall, with an AUC-ROC of 98.21%. Key capabilities include: • Real-time fraud scoring with sub-50ms latency per transaction • Intelligent alert prioritization that turns thousands of weekly alerts into high-confidence cases • Multi-dimensional risk analysis combining velocity patterns, geographic anomalies, and amount deviations • Visual investigation dashboard with transaction timelines and evidence summaries • Configurable detection thresholds for different risk appetites The platform features a comprehensive dashboard for fraud analysts with live transaction monitoring, severity-based alert management, ML model performance analytics, and an AI-powered fraud analyzer that explains predictions using feature importance visualization. Built for scale, CAREN processes transactions in real-time and provides actionable intelligence that reduces investigation time from hours to minutes while maintaining the highest detection accuracy.
