Spring 2023 (weeks 6 - 21). Lectures on Thursday 10:00-12:45 at the UvA, room SP C0.110.
Machine learning is one of the fastest growing areas of science, with far-reaching applications. In this course we focus on the fundamental ideas, theoretical frameworks, and rich array of mathematical tools and techniques that power machine learning. The course covers the core paradigms and results in machine learning theory with a mix of probability and statistics, combinatorics, information theory, optimization and game theory.
During the course you will learn to
This course strongly focuses on theory. (Good applied master level courses on machine learning are widely available, for example here, here and here). We will cover statistical learning theory including PAC learning, VC dimension, Rademacher complexity and Boosting, as well as online learning including prediction with expert advice, online convex optimisation, bandits and reinforcement learning.
This course is offered as part of the MasterMath program. To participate for credit, sign up here. We use the MasterMath ELO for submitting homework, and receiving grades.
We use the MasterMath Zulip MLTs23 stream as our forum. Sign up instructions are here.
The prerequisites are
as covered e.g. in any bachelor mathematics program in the Netherlands, and as reviewed in the Appendix of the book [1]. The course does require general 'mathematical maturity', in particular the ability to combine insights from all three fields when proving theorems.
We offer weekly homework sets whose solution requires constructing proofs. This course will not include any programming or data.
The lectures will be held on location at the UvA, room SP C0.110. To view them remotely, join the zoom live stream. Mastermath has kindly offered us recording support. Recorded lectures will be posted to our vimeo archive.
The Thursday 3h slot will consist of 2h of lectures followed by a 1h TA session discussing the homework.The grade will be composed as follows.
The average of midterm and final exam grades has to be at least 5.0 to pass the course.
It is strongly encouraged to solve and submit your weekly homework in small teams. Exams are personal.
There will be a retake possibility for either/both exams, which are 60% of the grade.
