PENN CIS 625, FALL 2020: THEORY OF MACHINE LEARNING
Prof. Michael Kearns
Tuesdays and Thursdays 10:30AM-Noon
Location: Virtual lectures via Zoom at this URL. All students are strongly encouraged to attend lectures "live" and with video on to increase engagement and interaction. However, all lectures will be recorded and notes provided to accomodate those in other time zones.
Office Hours: Prof. Kearns will hold office hours from noon to 1PM after each Tuesday's lecture at this URL.

This course is an introduction to the theory of machine learning, and provides mathematical, algorithmic, complexity-theoretic and probabilistic/statistical foundations to modern machine learning and related topics.
The first part of the course will follow portions of An Introduction to Computational Learning Theory, by M. Kearns and U. Vazirani (MIT Press). We will cover perhaps 6 or 7 of the chapters in K&V over (approximately) the first half of the course, often supplementing with additional readings and materials. Copies of K&V will be available at the Penn bookstore; I'm also looking into providing electronic access, as I do for the first chapter in the schedule below. The second portion of the course will focus on a number of models and topics in learning theory and related areas not covered in K&V.
The course will give a broad overview of the kinds of theoretical problems and techniques typically studied and used in machine learning, and provide a basic arsenal of powerful mathematical tools for analyzing machine learning problems.
Topics likely to be covered include:
COURSE FORMAT, REQUIREMENTS, AND PREREQUISITES
Much of the course will be in fairly traditional "chalk talk" lecture format (virtually on Zoom), but with ample opportunity for discussion, participation, and critique. The course will meet Tuesdays and Thursdays from 10:30 to noon, with the first meeting on Tuesday September 1.
The course will involve advanced mathematical material and will cover formal proofs in detail, and will be taught at the doctoral level. While there are no specific formal prerequisites, background or courses in algorithms, complexity theory, discrete math, combinatorics, convex optimization, probability theory and statistics will prove helpful, as will "mathematical maturity" in general. We will be examining detailed proofs throughout the course. If you have questions about the desired background, please ask. Auditors and occasional participants are welcome.
The course requirements for registered students will be a mixture of active in-class participation, problem sets, possibly leading a class discussion, and a final project. The final projects can range from actual research work, to a literature survey, to solving some additional problems.
