Our aim is to automate the extraction of knowledge and understanding from data. Allowing machines (and humans) to understand what is happening and to acquire new skills and learn new things. We achieve this by developing new probabilistic models and deriving algorithms capable of learnings these models from data. The systematic use of probability in representing and manipulating these models is key. It allows us to represent not only what we know, but to some extent also what we do not know. We take a particular interest in dynamical phenomena evolving over time.

Our research is multi-disciplinary and it sits somewhere on the intersection of the areas of Machine learning and statistics, signal processing, automatic control and computer vision. We pursue both basic and applied research, which explains our tight collaboration with various companies. A slightly more detailed overview of our research is available here.

Recent research results/news

[NEWS: We have just opened a tenure track position in Automatic Control] We are looking for a new member to join our team. A short informal overview of some of our research is available here and a link to the advertisment is available here. The Swedish title of the position is “Biträdande universitetslektor”. Feel free to contact me if you have questions of any kind.

May 11, 2018 [Paper accepted for ICML] We provide new results for the problem of predicting spatio-temporal processes with temporal patterns that vary across spatial regions, when data is obtained as a stream. More specifically, we develop a localized spatio-temporal covariance model of the process that can capture spatially varying temporal periodicities in the data. We then apply a covariance-fitting methodology to learn the model parameters which yields a predictor that can be updated sequentially with each new data point.

March 21, 2018 [First pre-release of our new probabilistic programming language Birch] Within our research project ASSEMBLE (funded by the Swedish Foundation for Strategic Research) we are developing a new probabilistic programming language, which we call Birch. Everyone is welcome to play with it. More information is available here.
