Gradescope Site: here.
Gradescope Entry Code: JKK5G3
Grading breakdown: Problem Sets 50%, Midterm 20%, Final Project OR Final Exam 20%, Partipation 10%
Final project guidelines: here.
Problem Sets: Problem sets must be turned in via GradeScope.
While not required, I encourage students to prepare problem sets in LaTeX or Markdown (with math support.)
You can use this template for LaTeX. While there is a learning curve, these tools typically save students time in the end! If you do write problems by hand, scan and upload as a PDF.
Collaboration is allowed on homework, but solutions and code must be written independently. Writing should not be done in parallel, and students must list collaborators for each problem separately.
Unless otherwise stated, referencing "nonstandard" theorems and proofs not given in class or previous problems is not allowed. All solutions must be proven from scratch. If you are unsure if you can use a fact, ask me or the TAs.
Prerequisites: This course is mathematically rigorous, and is intended for graduate students and advanced undergraduates. Formally we require previous courses in machine learning, algorithms, and linear algebra. Experience with probability and random variables is necessary. See the syllabus for more details and email Prof. Musco if you have questions about your preparation for the course!
Resources: There is no textbook to purchase. Course material will consist of my written lecture notes, as well as assorted online resources, including papers, notes from other courses, and publicly available surveys. Please refer to the course webpage before and after lectures to keep uptodate as new resources are posted.
Reading Group: It's an exciting time for research at the intersection of algorithm design and the data sciences. Most of the topics covered in this course are still the subject of active research.
Starting midway through the semester we will be holding a reading group for students working on final projects (and any others who wish) to discuss and workshop papers.
