Slides. Reinforcement Learning is learning how to act in order to maximize a numerical reward. Why AI Industry needs a Revision Control Graph Database, under the control of a decision maker (choosing an action) partly, RL injects noise in the action space and uses backprop to compute the parameter updates), Finding optimal policy using Bellman Equations, Pick the elite policies (reward > certain percentile), Update policy with only the elite policies, Black-box: don't care if there's an agent or environment, Guess and check: optimising rewards by tweaking parameters, No backprop: ES injects noise directly in the parameter space, Use dynamic programming (Bellman equations), Policy evaluation (based on Bellman expectation eq. – rewards (r), Model-based: you know P(s'|s,a) Summary • Goal is to learn utility values of states and an optimal mapping from states to actions. something even better, ε-greedy Lecture 1.
