Doctoral student in mathematics for AI: large-scale optimization

Kungliga Tekniska högskolan, School of Electrical Engineering and Computer Science

Project description

Third-cycle subject: Electrical Engineering

We are looking for a PhD student to join our efforts in developing theory for advanced machine learning within the research project "The mathematics of scalable optimization: asynchrony, adaption and information".

Optimization is the algorithmic workhorse of a lot of modern AI and machine learning. Increasingly often, learning and decision tasks are formulated, analyzed and solved as large-scale optimization problems. As these problems grow in size (for example, due to increasing amounts of data or a desire to coordinate ever more decisions) existing algorithms struggle to find a sufficiently good solution within a short time. This research project aims at developing fundamental theory and algorithms for which are able to solve large-scale optimization problem at an unprecedented speed, eventually supporting decision-making in real-time.

The research project is part of the Wallenberg AI, Autonomous Systems and Software Program, with focus on the mathematical aspects of AI.

Supervision: The doctoral student will be supervised by: Mikael Johansson
