The best way to learn and to avoid the illusion of competence is to test yourself. This will help you to find where you need to reinforce your knowledge.
The idea behind Actor-Critic is that we learn two function approximations:
policy
that controls how our agent acts (π)value
function to assist the policy update by measuring how good the action taken is (q)Instead of using directly the Action-Value function of the Critic as it is, we could use an Advantage
function. The idea behind an Advantage
function is that we calculate the relative advantage of an action compared to the others possible at a state, averaging them.
In other words: how taking that action at a state is better compared to the average value of the state
