Heart Artifact Removal in Electrohysterography Measurements Using Algebraic Differentiators
Amine Othmane, Maria Camila Bustos Vivas, Johannes Steuer +1
Electrohysterography (EHG) enables non-invasive monitoring of uterine contractions but can be contaminated by electrocardiogram (ECG) artifacts. This work presents an ECG removal m…
A data-based image representation for continuous-time LTI systems
Amine Othmane, Philipp Schmitz, Karl Worthmann +1
We derive a numerically stable method to compute an image representation of an unknown linear system only from data, leveraging a continuous-time version of Willems et al.'s fundam…
Optimality-Informed Neural Networks for Solving Parametric Optimization Problems
Matthias K. Hoffmann, Amine Othmane, Kathrin FlaÃkamp
Many engineering tasks require solving families of nonlinear constrained optimization problems, parametrized in setting-specific variables. This is computationally demanding, parti…
Neural network-enhanced integrators for simulating ordinary differential equations
Amine Othmane, Kathrin FlaÃkamp
Numerous applications necessitate the computation of numerical solutions to differential equations across a wide range of initial conditions and system parameters, which feeds the…
