Geodesics of Dynamic Graphs for Regime Change Detection

arXiv:2606.07151v1 Announce Type: new Abstract: 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 defining regimes as periods of coherent dynamics in temporal graphs, which we characterize as trajectories along geodesics in a suitably defined graph space. This original perspective allows us to define regime changes as significant drifts in dynamics, either toward new tra

Why this matters
Why now

The increasing complexity and dynamism of real-world networked systems necessitate more sophisticated methods for detecting critical changes beyond simplistic abrupt transitions.

Why it’s important

This research provides a more realistic framework for identifying significant 'regime changes' in complex evolving systems like social networks or physical infrastructures, offering improved foresight and intervention capabilities.

What changes

The ability to distinguish continuous evolution from meaningful 'drift' in dynamic graphs allows for more nuanced and accurate change point detection compared to traditional methods.
