Cumulative reward meaning
WebReinforcement learning (RL) is an area of machine learning concerned with how intelligent agents ought to take actions in an environment in order to maximize the notion of cumulative reward.Reinforcement learning is one of three basic machine learning paradigms, alongside supervised learning and unsupervised learning.. Reinforcement … WebMay 18, 2024 · My rewards system is this: +1 for when the distance between the player and the agent is less than the specified value. -1 when the distance between the player and the agent is equal to or greater than the specified value. My issue is that when I'm training the agent, the mean reward does not increase over time, but decreases instead.
