MIDAS: Microcluster-Based Detector of Anomalies in Edge Streams

11 Nov 2019bhatiasiddharth/MIDAS

Given a stream of graph edges from a dynamic graph, how can we assign anomaly scores to edges in an online manner, for the purpose of detecting unusual behavior, using constant time and memory?

SEDANSPOT: Detecting Anomalies in Edge Streams

ICDM 2018 dhivyaeswaran/sedanspot

Given a stream of edges from a time-evolving (un)weighted (un)directed graph, we consider the problem of detecting anomalous edges in near real-time using sublinear memory.
