Nonparametric approximation of conditional expectation operators

no code implementations23 Dec 2020 Mattes Mollenhauer, Péter Koltai

This also provides a novel perspective on which limiting object the nonparametric estimate of $P$ converges to.

Kernel Autocovariance Operators of Stationary Processes: Estimation and Convergence

no code implementations2 Apr 2020 Mattes Mollenhauer, Stefan Klus, Christof Schütte, Péter Koltai

We consider autocovariance operators of a stationary stochastic process on a Polish space that is embedded into a reproducing kernel Hilbert space.

Extending Transition Path Theory: Periodically-Driven and Finite-Time Dynamics

1 code implementation18 Feb 2020 Luzie Helfmann, Enric Ribera Borrell, Christof Schütte, Péter Koltai

Given two distinct subsets $A, B$ in the state space of some dynamical system, Transition Path Theory (TPT) was successfully used to describe the statistical behavior of transitions from $A$ to $B$ in the ergodic limit of the stationary system.

Dimensionality Reduction of Complex Metastable Systems via Kernel Embeddings of Transition Manifolds

1 code implementation18 Apr 2019 Andreas Bittracher, Stefan Klus, Boumediene Hamzi, Péter Koltai, Christof Schütte

We present a novel kernel-based machine learning algorithm for identifying the low-dimensional geometry of the effective dynamics of high-dimensional multiscale stochastic systems.
