Course Overview

This course will first introduce topics on machine learning, security, privacy, fairness, robust learning, and game theory; then from the research perspective, we will discuss the fundamental contributions and potential extension for each topic as well as corresponding open challenges, with a focus on the algorithm and system perspectives. Students will understand different machine learning algorithms, analyze their implementation and security vulnerabilities through a series of readings and projects, and develop the ability to conduct research projects on related topics.

Prerequisites: CS 446 Machine Learning, CS 461 Computer Security I (CS 463 Computer Security II)

Please contact the instructor if you have questions regarding the material or concerns about whether your background is suitable for the course.

Grading

The course will involve one paper presentation, three reading reviews, and a final project. Unless otherwise noted by the instructor, all work in this course is to be completed independently. If you are ever uncertain of how to complete an assignment, you can go to office hours or engage in high-level discussions about the problem with your classmates on the Canvas boards.

Grades will be assigned as follows:

Presentation: Each student will present 1~2 papers (based on the hardness of the paper) for a specific topic. Students need to sign up for the presentation in this Google Sheet (please log in with Illinois credentials to edit it). The presentation quality will take 20% of your grade.
Paper Reviews: Each student will submit three paper reviews for the papers not in your presentation pile. The three reviews will take 10% of your grade. You can submit more than three and the highest three scores will be selected. You can find the guidelines here in the Google Doc (please log in with Illinois credentials to view it). You should submit the reviews on Canvas.
Final Project: Students will form groups of two and work on a final project. A final project report will be submitted by ~~12/2~~ 12/14 midnight. ~~and the final presentation will be scheduled (The spreadsheet for signup will be posted here~~ The final presentation will take place on Dec. 6. Please sign up and add your slides following the instructions here: Google Slides Link (please log in with Illinois credentials to view it). The quality of the final project will take 65% of your final grade.
Participation: Accounts for 5%. Includes quizzes and class discussion (either in person or online).

Course Expectations

The expectations for the course are that students will attend every class, do any readings assigned for class, and actively and constructively participate in class discussions. Class participation will be a measure of contributing to the discourse both in class, through discussion and questions, and outside of class through contributing and responding to the Canvas forum.

More information about course requirements will be made available leading up to the start of classes.
