Informed Asymmetric Actor-Critic: Leveraging Privileged Signals Beyond Full-State Access
Researchers have developed a new framework called the informed asymmetric actor-critic method to improve reinforcement learning in partially observable environments. This approach allows the critic to utilize specific, state-dependent privileged signals during training, which can lead to unbiased policy gradient estimates. The framework also introduces criteria for selecting the most informative signals, demonstrating that carefully chosen signals can match or exceed the performance of full-state methods while requiring less information.
