Preprint: Discovery of Nonlinear Dynamical Systems using a Runge-Kutta Inspired Dictionary-based Sparse Regression Approach

May 11, 2021
This work by Pawan Goyal (CSC) and Peter Benner (CSC) combines machine learning (dictionary-based) with a numerical integration scheme, namely a Runge-Kutta scheme to discover governing equations using corrupted and sparsely-sampled data. The method does not require the computation of derivative information to discover governing equations. Hence, it holds a key advantage when data are corrupted and sparsely sampled.

Paper: Learning Reduced order Dynamics for Parametrized Shallow Water Equations from Data

May 10, 2021
This paper by Süleyman Yildiz (METU Ankara), Pawan Goyal (CSC), Peter Benner (CSC), and Bülent Karasözen (METU Ankara) discusses learning reduced models for parameterized shallow water equations using only data. The article is published in International Journal for Numerical Methods in Fluids.

April 30, 2021
handoverThis paper by J. Fehr (Uni Stuttgart), C. Himpe (CSC), S. Rave (WWU Münster) and J. Saak (CSC) intends to be a bottom-up approach for sustainable hand-over processes in scientific software development from a developer’s perspective. It got published in the Journal of Open Research Software today.

Software: M-M.E.S.S.-2.1: New feature release

April 30, 2021
mmessThe M.E.S.S. development team releases version 2.1 of the MATLAB and OCTAVE toolbox. The new version contains further improvements to the MOR functions, as well as various minor bug fixes. Most importantly, this version provides new solvers for Lyapunov-plus-positive equations and support for the new sparss and mechss system classes in Matlab
