Models for evolutionary processes like physical systems are conceptualized via continuous  dynamical systems. However, in general, the model is unknown and only finite data is observed, hence, it is a significant challenge to learn a continuous function that describes the desired dynamical system robustly. To address this, data-driven dynamics are being increasingly employed in order to identify the underlying dynamics based on finite data.

To overcome the gap between the complexity of a continuous system and the  description based on finite data, we use a Gaussian process as a surrogate model together with combinatorial dynamics to capture the global behavior of the underlying function that generates the dynamics. After introducing the main ideas, I will show some applications to robotic systems.
