One of the most fundamental problems when designing controllers for dynamic systems is the tuning of the controller parameters. ...
It models the underlying performance measure as a Gaussian process and only explores new controller parameters whose performance lies above a safe performance threshold with high probability. ...
For example, we may set the threshold at 95% of the performance of the initial control law. Conceptually, this ensures stability, since unstable systems have a significantly lower performance.
