Fast Reinforcement Learning for Anti-jamming Communications
, 2020 This letter presents a fast reinforcement learning algorithm for anti-jamming communications which chooses previous action with probability $ $ and applies $ $-greedy with probability $(1- )$. A dynamic threshold based on the average value of previous several actions is designed and probability $ $ is formulated as a Gaussian-like function to guide

What attention is. The priority structure account
WIREs Cognitive Science, Volume 14, Issue 1, January/February 2023., 2023 Attention is what organizes current information to make it more useful for the organism. We can identify it by four features. Attention, in this way, helps a cognitive system to integrate its informational state with its current motivational state.
