Course overview: The course provides an introduction to machine learning, focusing on supervised learning and its theoretical foundations. Topics include regularized linear models, boosting, kernels, deep networks, generative models, online learning, and ethical questions arising in ML applications.

Prerequisites: probability theory (e.g. BTRY 3080, ECON 3130, MATH 4710, ENGRD 2700), linear algebra (e.g. MATH 2940), calculus (e.g. MATH 1920), and programming proficiency (e.g. CS 2110).

Course logistics: For enrolled students the companion Canvas page serves as a hub for access to Ed Discussions (the course forum), Vocareum (for course projects), Gradescope (for HWs), and paper comprehension quizzes. If you are enrolled in the course you should automatically have access to the site. Please let us know if you are unable to access it.

Homework, projects, and exams


Your grade in this course is comprised of three components: homework, exams, and projects. Please also read through the given references in concert with the lectures.

Grading

Final grades are based on homework assignments, programming projects, and the exams. For the 5780 level version of the course, the research comprehension quizzes will also factor in.

For CS 4780 your final grade consists of: For CS 5780 your final grade consists of:

Undergraduates enrolled in 4780 may choose to do the paper comprehension assignments; if completed you will receive the higher of your two grades between the above schemes.

Schedule


A tentative schedule follows, and includes the topics we will be covering, relevant reference material, and assignment information. It is quite possible the specific topics covered on a given day will change slightly. This is particularly true for the lectures in the latter part of the course, and this schedule will be updated as necessary. Please note that the due dates here are mostly correct, but may change. Check Canvas for any changes to assignment due dates.

References


While this course does not explicitly follow a specific textbook, there are several that are very useful references to supplement the course.

Books

We will not be explicitly following any single textbook in this course. Nevertheless, the book by Murphy roughly cover the material for the course and is recommended. Most suggested readings are assigned out of these two texts. Three additional texts are provided that complement these texts and are useful for further study (or to gain another perspective).
