WebReinforcement learning (RL) has seen a resur-gence of interest as the methodology has been combined with deep learning neural networks. Advances in hardware and software have enabled RL in achieving newsworthy successes, such as learning to surpass human-level performance in video games (Mnih et al., 2013) and beating WebGreedy policy, Q values are initialized to 0.1 to induce exploration. Same greedy policy but uses eligibility traces to make learning considerably faster. Uses epsilon-greedy policy and eligibility traces, turns out to be …

The policy is a mapping from the states to actions or a probability distribution of actions.
WebMDPs and value iteration. Value iteration is an algorithm for calculating a value function V, from which a policy can be extracted using policy extraction. It produces an optimal policy an infinite amount of time. For medium-scale problems, it works well, but as the state-space grows, it does not scale well. WebQuestion 5.
