DOI: 10.1007/s10514-017-9636-y
Abstract: An important challenge when using reinforcement learning for learning motions in robotics is the choice of parameterization for the policy. We use Gaussian Mixture Regression to extract a parameterization with relevant non-linear features from a… read more here.

DOI: 10.1007/s40435-018-0408-0
Abstract: Many identification strategies for closed loop linear time invariant system assume that an open loop system is closed by a feedback mechanism, which contains a known, linear time invariant controller. This assumption means that these… read more here.
