Anomaly Detection in Time Series of Graphs using Fusion of Graph Invariants

Youngser Park, Carey E. Priebe, Abdou Youssef

Given a time series of graphs G(t) = (V, E(t)), t = 1, 2, ..., where the fixed vertex set V represents "actors" and an edge between vertex u and vertex v at time t (uv \in E(t)) re…
