Supervised Learning and Reinforcement Learning

For supervised learning you're intentionally injecting in what the correct labels are that you want. For unsupervised learning a human has to go through by hand and figure it out so there's an obvious injection of knowledge from the human with unsupervisedlearning there's no obvious less obvious of an injection ofknowledge from the human. With reinforcement learning you're trying to generate the knowledge out of some sort of signal in the environment.
