Shape-constrained Symbolic Regression with NSGA-III

no code implementations28 Sep 2022 Christian Haider

Both algorithms are capable of dealing with multiple objectives, whereas NSGA-II is a well established multi-objective approach performing well on instances with up-to 3 objectives.

Using Shape Constraints for Improving Symbolic Regression Models

no code implementations20 Jul 2021 Christian Haider, Fabricio Olivetti de França, Bogdan Burlacu, Gabriel Kronberger

We describe and analyze algorithms for shape-constrained symbolic regression, which allows the inclusion of prior knowledge about the shape of the regression function.

Shape-constrained Symbolic Regression -- Improving Extrapolation with Prior Knowledge

no code implementations29 Mar 2021 Gabriel Kronberger, Fabricio Olivetti de França, Bogdan Burlacu, Christian Haider, Michael Kommenda

Both algorithms are able to identify models which conform to shape constraints which is not the case for the unmodified symbolic regression algorithms.
