How to solve overestimation problem rl
WebNov 30, 2024 · The problem it solves. A problem in reinforcement learning is overestimation of the action values. This can cause learning to fail. In tabular Q-learning, the Q-values will converge to their true values. The downside of a Q-table is that it does not scale. For more complex problems, we need to approximate the Q-values, for example with a DQN ... WebA best practice when you apply RL to a new problem is to do automatic hyperparameter optimization. Again, this is included in the RL zoo . When applying RL to a custom problem, you should always normalize the input to the agent (e.g. using VecNormalize for PPO/A2C) and look at common preprocessing done on other environments (e.g. for Atari ...
