WebApr 8, 2024 · Policy Gradient#. The goal of reinforcement learning is to find an optimal behavior strategy for the agent to obtain optimal rewards. The policy gradient methods target at modeling and optimizing the policy directly. The policy is usually modeled with a parameterized function respect to $\theta$, $\pi_\theta(a \vert s)$. WebApr 30, 2024 · We stayed in our sandbox. The field of behavioral public policy has promoted the use of low-cost framing and related interventions to change behavior, in contrast to heavy-handed laws and incentives. In the present crisis, among the most powerful tools for promoting social distancing have been mandates from national and local governments.

WebSutton et al., 2016], with off-policy samples the TD algorithm may diverge; also see §3.3. This is due to the non-Hurwitz matrix which forms the mean field of update, since the behavior and target policies are mismatched. Below, we develop an algorithm similar to gradient-based TD (GTD) learning which is shown to resolve the non-convergent issue.
