Algorithmic Statistics (6.S896), Fall '23, MIT
Prerequisites: Mathematical maturity is the main prerequisite. Familiarity with linear algebra, probability, discrete math, and algorithms at the advanced undergraduate level will be assumed.
Meeting time: Tuesdays and Thursdays, 2:30pm-4:00pm
Location: 32-124
Instructors: Costis Daskalakis and Sam Hopkins
Office Hours: Thursday 4-6 pm (after class) 32-G5 Lounge or by appointment
Evaluation: Students will be expected to complete two problem sets and a research-oriented course project, which may consist of original research (theoretical and/or experimental!) and/or an exposition of 1 or 2 recent research papers. Tentatively, weight for your final grade will be split as follows: 25% pset 1, 25% pset 2, 50% course project.
Problem Set Partners: We have activated problem set partner matching for this course. See this website
