Overview, in brief. Marriage between statistics, linear algebra, calculus, and computer science. Machine Learning:. Supervised Learning. ex: linear Regression. Unsupervised Learning. ex: clustering. vs. Discriminative models. Roughly:. Discriminative. Feedforw. ard. Bottom-up. Generative. Feedforward recurrent feedback. Bottom-up horizontal top-down.
