3. “A computer program is said to learn from
experience (E) with respect to some class of
tasks (T) and performance measure (P), if its
performance at tasks in T, as measured by P,
improves with experience E.” –Tom Mitchell
Robot Navigation in a MAZE

6. Supervised: the computer is provided with
example inputs that are labeled with their
desired outputs
Unsupervised: the data is unlabeled, so the
learning algorithm is left to find commonalities
among its input data.
Reinforcement: Concerned with how software
agents ought to take action in an environment
so as to maximize some notion of cumulative
reward.
