Sign up for final project presentation here.
Focuses 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. Requirements for grading (other than attending lectures) are: scribing one lecture, 2 problems sets, final project.
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.
GradingRequirements for grading (other than attending lectures) are: scribing one lecture, 2 problems sets, final project.
In this class we will scribe 13 lectures: lectures #2 - #11, and lectures #14 - #16. Each student who is taking this class for credit will be required to scribe one lecture. Scribe notes should be a natural integration of the presentation of the lectures with the material in the slides. The lecture slides are available on this website for your reference. Good scribe notes are important, both for your grades and for other students to read. In particular, please make an effort to present the material in a clear, concise, and comprehensive manner. You can look at the lecture notes of 6.854/18.415 (Fall 2008) on OCW to see examples of the expected format and quality of scribe notes.
Scribe notes must be prepared with Latex, using this template. Scribe notes (.tex file and all additional files) should be submitted to email@example.com no later than one week after the class. Please make sure to proofread the notes carefully before submitting. We will review the scribe notes to check the technical content and quality of writing. We will also give feedback and ask for a revised version if necessary. Completed scribe notes will be posted on this website as soon as possible.
You can sign up here for scribe notes. If you have problems opening or editing the page, please send us an email at firstname.lastname@example.org. In addition, if you have any questions of concerns about the scribing requirement, please feel free to send us an email.
