Mathematics of Information


Group overview

 As modern society creates, processes, and interprets data faster than ever before and then uses it for a variety of tasks, the need for rigorous understanding of the algorithms and mechanisms used to process this data is ever necessary. The mathematics of information group at UBC studies the theoretical underpinnings of modern data science with the aim of designing new algorithms, and understanding their mathematical mechanisms.

 Areas of interest in the group include machine learning theory and applications, large-scale optimization, compressed sensing, deep learning theory, high-dimensional inference, matrix completion, ergodic theory, symbolic dynamics, causality, tensor methods, algebraic statistics, optimal transport theory and applications.


Students are encouraged to take topics courses offered by the core faculty in the group. Besides the Mathematics of Information seminar, a variety of other seminars (which can be found on the IAM events website) are relevant, for example, the IAM colloquium and the probability seminar.
