10-715 Fall 2022: Advanced Introduction to Machine Learning

This course is designed for Ph.D. students whose primary field of study is machine learning, or who intend to make machine learning methodological research a main focus of their thesis. It will give students a thorough grounding in the algorithms, mathematics, theories, and insights needed to do in-depth research and applications in machine learning. The topics of this course will in part parallel those covered in the general graduate machine learning course (10-701), but with a greater emphasis on depth in theory and algorithms. The course will also include additional recent topics such as fairness in machine learning.

IMPORTANT NOTE: Students entering the class are expected to have a pre-existing strong working knowledge of linear algebra (e.g., mathematical representation of subspaces, singular value decomposition), probability (e.g., multivariate Gaussians, Bayes' rule, conditional expectation), and calculus (e.g., derivative of a vector with respect to another vector), and programming (we'll mostly be supporting Python). This class is best for you if you have machine learning at the CORE of your studies/research, and want to understand the fundamentals. This class will be HEAVY and will move FAST. If machine learning is an auxiliary component of your studies/research or if you do not have the required background, you may consider the general graduate Machine Learning course (10-701) or the Masters-level Machine Learning course (10-601). Click here for an ML course comparison. Note that machine learning itself is NOT a prerequisite for this course.
Also note that by departmental policy, this course is open only to graduate students (5th year masters are allowed).

Waitlist: The waitlist will be processed near end of summer.

Time and location: The class is scheduled for Monday and Wednesday 10.10am to 11.30am in TBD venue. We will reserve Fridays for recitations, which will be held 10.10am to 11.30am in the same location.

Units: 12

Instructor: Nihar B. Shah

Textbook: [SB] Understanding Machine Learning: From Theory to Algorithms by Shai Shalev-Shwartz and Shai Ben-David (available online)

Here is the syllabus from the 2021 edition. It will remain the same in 2022. The dates will change: Note that most lectures will be taught on the "board'', and hence there are no "slides''.

Accommodations for Students with Disabilities: If you have a disability and have an accommodations letter from the Disability Resources office, I encourage you to discuss your accommodations and needs with me as early in the semester as possible. I will work with you to ensure that accommodations are provided as appropriate. If you suspect that you may have a disability and would benefit from accommodations but are not yet registered with the Office of Disability Resources, I encourage you to contact them at access@andrew.cmu.edu.

Finally, to all students: Please take care! The COVID pandemic can lead to stress and uncertainty and can take its toll on our mental health. Make sure to move regularly, eat well, and reach out to your support system or me if you need to. We can all benefit from support in times of stress, and this semester is no exception.
