    Jun 13, 2019· The third type of machine learning, and the type of particular interest in price setting by firms, is reinforcement learning, in which algorithms learn to take actions in an unknown but fixed environment to maximize some sort of cumulative reward. The output is an action or sequence of actions, and the only supervisory signal is a (scalar) reward.
