MIDAS: Detecting Microcluster Anomalies in Edge Streams
A real-time anomaly detection algorithm for dynamic graph streams, identifying intrusions, fraud, and fake ratings with constant memory and update time.
What is MIDAS: Detecting Microcluster Anomalies in Edge Streams?
MIDAS is a real-time anomaly detection algorithm for dynamic, time-evolving graphs. It processes streaming edge data to identify microcluster anomalies such as intrusions (DoS/DDoS attacks), financial fraud, and fake ratings. The algorithm provides constant memory usage and update time, making it scalable for high-velocity graph streams.
Data scientists and engineers working on network security, fraud detection, or social media analysis who need real-time anomaly detection in graph-structured data streams.
Developers choose MIDAS for its combination of theoretical guarantees, constant-time performance, and high accuracy—outperforming state-of-the-art methods by up to 55% in accuracy and 929× in speed.
