Persistence-Based Statistics for Detecting Structural Changes in High-Dimensional Point Clouds
Toshiyuki Nakayama
We study the probabilistic behavior of persistence-based statistics and propose a novel nonparametric framework for detecting structural changes in high-dimensional random point cl…

Distance between closed sets and the solutions to stochastic partial differential equations
Toshiyuki Nakayama, Stefan Tappe
The goal of this paper is to clarify when the solutions to stochastic partial differential equations stay close to a given subset of the state space for starting points which are c…
