Reinforcement Learning is learning what to do and how to map situations to actions. The end result is to maximize the numerical reward signal. The learner is not told which action to take, but instead must discover which action will yield the maximum reward. Let's understand this with a simple example below Reinforcement learning can be considered the third genre of the machine learning triad - unsupervised learning, supervised learning and reinforcement learning. In supervised learning, we supply the machine learning system with curated (x, y) training pairs, where the intention is for the network to learn to map x to y This is the first part of a tutorial series about reinforcement learning.
