How to Learn a Useful Critic? Model-based Action-Gradient-Estimator Policy Optimization

NeurIPS 2020poster

Deterministic-policy actor-critic algorithms for continuous control improve the actor by plugging its actions into the critic and ascending the action-value gradient, which is obtained by chaining the actor's Jacobian matrix with the gradient of the critic with respect to input actions. However, ins…
