Positive reinforcement is one of four types of reinforcement in operant conditioning theory of human behavior (see our article on Positive Reinforcement in Psychology) and one of many approaches to parenting. This course introduces you to statistical learning techniques where an agent explicitly takes actions and interacts with the world. The proposed method first describes the control plant within the RL environment. To do so, we have created one of the largest imitation learning datasets with over 60 million frames of recorded human player data. Reinforcement Learning has the ability to specialize in specific tasks which it learns by repeating it over and over, hence in the domain of NLP it has yielded significant results for Merging this paradigm with the empirical power of deep learning is an obvious fit.
