AS-SRDT: Semi-Supervised Anomaly Detection for IEC 61850 GOOSE Communication Using Anomaly-Score Supervision With Restricted Distribution Transformation

A semi-supervised anomaly detection framework that incorporates explicit anomaly-score supervision into the restricted distribution transformation paradigm is proposed and demonstrates that the proposed approach consistently outperforms baseline anomaly detection methods in terms of Matthews Correlation Coefficient (MC...
