Unsupervised Learning

Supervised Learning

The supervised learning is a density estimation problem related with determining the properties of $P(Y|X)$.

$$\mu(x) =argmin_\theta E_{Y|X} L(Y,\theta)$$

Unsupervised Learning

Unlike the supervised learning, unsupervised learning directly infers the properties of $P(X)$ without the help of a supervisor($Y$).
