ParFam -- Symbolic Regression Based on Continuous Global Optimization

1 code implementation9 Oct 2023 Philipp Scholl, Katharina Bieker, Hillary Hauger, Gitta Kutyniok

In this paper, we present our new method ParFam that utilizes parametric families of suitable symbolic functions to translate the discrete symbolic regression problem into a continuous one, resulting in a more straightforward setup compared to current state-of-the-art methods.

On the Treatment of Optimization Problems with L1 Penalty Terms via Multiobjective Continuation

no code implementations14 Dec 2020 Katharina Bieker, Bennet Gebken, Sebastian Peitz

We present a novel algorithm that allows us to gain detailed insight into the effects of sparsity in linear and nonlinear optimization, which is of great importance in many scientific areas such as image and signal processing, medical imaging, compressed sensing, and machine learning (e. g., for the training of neural networks).
