WebFeb 18, 2024 · Q-learning learns the action-value function Q (s, a): how good to take an action at a particular state. Basically a scalar value is assigned over an action a given the state s. The following... Q-learning is a model-free reinforcement learning algorithm to learn the value of an action in a particular state. It does not require a model of the environment (hence "model-free"), and it can handle problems with stochastic transitions and rewards without requiring adaptations. For any finite Markov decision … See more Reinforcement learning involves an agent, a set of states $${\displaystyle S}$$, and a set $${\displaystyle A}$$ of actions per state. By performing an action $${\displaystyle a\in A}$$, the agent transitions from … See more Learning rate The learning rate or step size determines to what extent newly acquired information overrides old information.
