A non-intrusive approach to index-aware learning
Peter Förster, Idoia Cortes Garcia, Wil Schilders +1
We present a non-intrusive version of the index-aware learning framework introduced in arXiv:2309.00958. Index-aware learning itself is an approach for learning the time and parame…

A topological decoupling of modified nodal analysis including controlled sources
Idoia Cortes Garcia, Peter F. Förster, Lennart Jansen +2
We derive a topological decoupling of the equations of modified nodal analysis (MNA) to a semi-explicit index one differential-algebraic equation. The decoupling explicitly allows…

Learning solutions of parameterized stiff ODEs using Gaussian processes
Idoia Cortes Garcia, P. Förster, W. Schilders +1
Stiff ordinary differential equations (ODEs) play an important role in many scientific and engineering applications. Often, the dependence of the solution of the ODE on additional…
