Learning phase-space flows using time-discrete implicit Runge-Kutta PINNs
Álvaro Fernández Corral, Nicolás Mendoza, Armin Iske +2
We present a computational framework for obtaining multidimensional phase-space solutions of systems of non-linear coupled differential equations, using high-order implicit Runge-K…

Finetuning greedy kernel models by exchange algorithms
Tizian Wenzel, Armin Iske
Kernel based approximation offers versatile tools for high-dimensional approximation, which can especially be leveraged for surrogate modeling. For this purpose, both "knot inserti…
