Course descriptionFocuses on the problem of supervised and unsupervised learning from the perspective of modern statistical learning theory, starting with the theory of multivariate function approximation from sparse data. Develops basic tools such as regularization, including support vector machines for regression and classification. Derives generalization bounds using stability. Discusses current research topics such as manifold regularization, sparsity, feature selection, bayesian connections and techniques, and online learning. Emphasizes applications in several areas: computer vision, speech recognition, and bioinformatics. Discusses advances in the neuroscience of the cortex and their impact on learning theory and applications. The course is graded on the basis of final projects and hands-on applications and exercises.
Prerequisites6.867 or permission of instructor. In practice, a substantial level of mathematical maturity is necessary. Familiarity with probability and functional analysis will be very helpful. We try to keep the mathematical prerequisites to a minimum, but we will introduce complicated material at a fast pace.
GradingThere will be two problem sets and a final project. To receive credit, you must attend regularly, and put in effort on all problem sets and the project.
Problem setsProblem set #1: PDF --
Problem set #2: PDF -- Due Mon. April 13th (in class)
ProjectsProject ideas: PDF
