Constructing Parsimonious Analytic Models for Dynamic Systems via Symbolic Regression

1 code implementation27 Mar 2019 Erik Derner, Jiří Kubalík, Nicola Ancona, Robert Babuška

We demonstrate on a real pendulum system that the analytic model found enables a RL controller to successfully perform the swing-up task, based on a model constructed from only 100 data samples.
