Reinforcement Learning It is an area of machine learning where a RL agent learns from the consequences of its actions, rather than from being taught explicitly. It selects its actions on basis of its past experiences (exploitation) and also by new choices (exploration). Q- learning ALGORITHMS: SARSA DQN
