This course provides a broad introduction to machine learning and statistical pattern recognition. Reinforcement 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 learning differs from supervised learning in not needing . Equation (1). Work fast with our official CLI. There is a tradeoff between a model's ability to minimize bias and variance.
