Neuroinformatics Group at University of Helsinki

Neuroinformatics is widely defined as the cross-fertilization of information-processing and mathematical sciences on the one hand, and neural and cognitive sciences on the other.

Our group works on different aspects of neuroinformatics related to machine learning. Some example include:

  • We apply machine learning models on neuroimaging data, in particular MEG.
  • We model the visual system in the brain by analyzing the statistical structure of the natural input images.
  • We develop the relevant theory of statistical machine learning, typically unsupervised.

The group is located at the department of Computer Science of the U Helsinki and its leader is Aapo Hyvärinen.
