New method detects regime changes in dynamic graphs

By PulseAugur Editorial · [2 sources] ·

Researchers have developed a new method for detecting regime changes in dynamic graphs, moving beyond traditional abrupt transition models. This approach defines regimes as periods of coherent dynamics, characterized by trajectories along geodesics in a graph space. By measuring drifts in these dynamics, the method can identify significant changes, outperforming existing models on various experiments and aligning detected changes with external events like the COVID-19 pandemic.

    Geodesics of Dynamic Graphs for Regime Change Detection

    Traditional change point detection in dynamic networks assumes abrupt transitions between stationary states, overlooking scenarios of continuous evolution which arise in most real-world applications, such as social networks or physical systems. We address this gap by formally def…
