Multiple change-point detection on the circle via isolation using permutation testing
Sophia Loizidou, Andreas Anastasiou, Christophe Ley
In this paper we propose a new method for multiple change-point detection for piecewise-constant circular signals, a setting that, despite its importance in many scientific domains…
Construction of optimal tests for symmetry on the torus and their quantitative error bounds
Andreas Anastasiou, Christophe Ley, Sophia Loizidou
In this paper, we develop optimal tests for symmetry on the hyper-dimensional torus, leveraging Le Cam's methodology. We address both scenarios where the center of symmetry is know…
Data-adaptive structural change-point detection via isolation
Andreas Anastasiou, Sophia Loizidou
In this paper, a new data-adaptive method, called DAIS (Data Adaptive ISolation), is introduced for the estimation of the number and the location of change-points in a given data s…
Non-parametric multiple change-point detection
Andreas Anastasiou, Piotr Fryzlewicz
We introduce a methodology, labelled Non-Parametric Isolate-Detect (NPID), for the consistent estimation of the number and locations of multiple change-points in a non-parametric s…
