Course structure


We will post important announcements, links, and other information here in the course of the semester, so please check back often!

Course Info

The class focuses on mathematical aspects of information science and learning theory.

We encourage students who are interested in mathematical data science to take both this course and "401-4944-20L Mathematics of Data Science" by Prof. A. Bandeira. The two courses are designed to be complementary.

H. Bölcskei and A. Bandeira


This course is aimed at students with a background in linear algebra, probability, and basic functional analysis. In particular, familiarity with Hilbert spaces is expected on the level of the "Hilbert spaces" chapter posted below (excluding the appendices).
