Detecting Anomalous Activity on Networks with the Graph Fourier Scan Statistic
James Sharpnack, Alessandro Rinaldo, Aarti Singh
We consider the problem of deciding, based on a single noisy measurement at each vertex of a given graph, whether the underlying unknown signal is constant over the graph or there…
Confidence sets for persistence diagrams
Brittany Terese Fasy, Fabrizio Lecci, Alessandro Rinaldo +3
Persistent homology is a method for probing topological properties of point clouds and functions. The method involves tracking the birth and death of topological features (2000) as…
Changepoint Detection over Graphs with the Spectral Scan Statistic
James Sharpnack, Alessandro Rinaldo, Aarti Singh
We consider the change-point detection problem of deciding, based on noisy measurements, whether an unknown signal over a given graph is constant or is instead piecewise constant o…
