The system designer assumes, in a Bayesian probability-driven fashion, that random noise with known probability distribution affects the evolution and observation of the state variables. Note the similarity to the conventional Bellman equation, which instead has the hard max of the Q-function over the actions instead of the softmax.

Optimal control focuses on a subset of problems, but solves these problems very well, and has a rich history. Reinforcement Learning 4 / 36. Reinforcement Learning (RL) is a powerful tool to perform data-driven optimal control without relying on a model of the system. Average Cost Optimal Control of Stochastic Systems Using Reinforcement Learning. By using Q-function, we propose an online learning scheme to estimate the kernel matrix of Q-function and to update the control gain using the data along the system trajectories.

Reinforcement learning (RL) is an area of machine learning concerned with how software agents ought to take actions in an environment in order to maximize the notion of cumulative reward. (Posterior Policy Iteration) Implement and experiment with existing algorithms for learning control policies guided by reinforcement, expert demonstrations or self-trials. We motivate and devise an exploratory formulation for the feature dynamics that captures learning under exploration, with the resulting optimization problem being a revitalization of the classical relaxed stochastic control.
