Learning switched non-linear dynamical systems from a single trajectory
Sunny G. W. Wang, Hemant Tyagi
We study empirical risk minimization for learning non-linear dynamical systems whose transition dynamics may switch over time. Under stability assumptions, and i.i.d switching over…

Adaptive functional principal components analysis
Sunny G. W. Wang, Valentin Patilea, Nicolas Klutchnikoff
Functional data analysis almost always involves smoothing discrete observations into curves, because they are never observed in continuous time and rarely without error. Although s…

Rate accelerated inference for integrals of multivariate random functions
Valentin Patilea, Sunny G. W. Wang
The computation of integrals is a fundamental task in the analysis of functional data, which are typically considered as random elements in a space of squared integrable functions.…
