The astounding performance and applicability of machine learning in an ever-increasing number of applications have not been paired with a sufficient understanding of its mathematical foundations, preventing it from application to critical fields where human safety and health are of interest. This workshop aims to present and discuss results laying firm mathematical foundations of design, implementation, and evaluation of machine learning algorithms using tools of linear algebra, functional analysis, probability theory, statistics, optimization, and information theory.
