Anomaly detection in Cyber-Physical Systems

 

This deep learning project tried to detect anomalies in real time. I collaborated with DASH lab members.

The given dataset is error data generated by deep learning model. Original dataset is SWaT (Secure Water Treatment) dataset and HAI (HIL-based Augmented ICS) security dataset.
