Inverse Optimal Control
نویسنده
چکیده
In Reinforcement Learning, an agent learns a policy that maximizes a given reward function. However, providing a reward function for a given learning task is often non trivial. Inverse Reinforcement Learning, which is sometimes also called Inverse Optimal Control, addresses this problem by learning the reward function from expert demonstrations. The aim of this paper is to give a brief introduction to Inverse Reinforcement Learning. It thereby focuses on two recent approaches which employ Gaussian Processes to learn nonlinear reward functions and maximum causal entropy to model the experts behavior. While the first approach is infeasible if the state space is too large, the second, more recent approach was successfully applied to high dimensional and continuous learning tasks.

متن کاملEquivalent a posteriori error estimates for spectral element solutions of constrained optimal control problem in one dimension
In this paper, we study spectral element approximation for a constrained optimal control problem in one dimension. The equivalent a posteriori error estimators are derived for the control, the state and the adjoint state approximation. Such estimators can be used to construct adaptive spectral elements for the control problems.
