This means better performing scenarios will run for longer duration, accumulating larger return.
WebMay 10, 2024 · Reinforcement learning (RL) is an area of machine learning concerned with how software agents ought to take actions in an environment in order to maximize the notion of cumulative reward. WebFor this, we introduce the concept of the expected return of the rewards at a given time step. For now, we can think of the return simply as the sum of future rewards. Mathematically, we define the return G at time t as G t = R t + 1 + R t + 2 + R t + 3 + ⋯ + R T, where T is the final time step. It is the agent's goal to maximize the expected ...
WebNov 15, 2024 · The ‘Q’ in Q-learning stands for quality. Quality here represents how useful a given action is in gaining some future reward. Q-learning Definition.
