Reinforcement Learning 101

Reinforcement Learning(RL) is one of the hottest research topics in the field of modern Artificial Intelligence and its popularity is only growing. Let's look at 5 useful things one needs to know to get started with RL. Reinforcement Learning(RL) is a type of machine learning technique that enables an agent to learn in an interactive environment by trial and error using feedback from its own actions and experiences. Though both supervised and reinforcement learning use mapping between input and output, unlike supervised learning where the feedback provided to the agent is correct set of actions for performing a task, reinforcement learning uses rewards and punishments as signals for positive and negative behavior. As compared to unsupervised learning, reinforcement learning is different in terms of goals.
