Who am I?

I am a professor of data science at UEF's School of Computing, at Kuopio campus. Formerly I was a senior researcher at Max Planck Institute for Informatics in Saarbrücken, Germany. I am also a docent (adjunct professor) at University of Helsinki.

I study algorithmic data analysis, and I am interested to both theory and applications thereof. I lead the Algorithmic Data Analysis research group at UEF. My main research has been in the fields of Boolean and (sub-) tropical matrix and tensor factorizations, redescription mining, and social network analysis. You can find my publications in my Publications page.

What's new

• Charmin Asirimath joins the group as a part of the Finnish Doctoral Program Network in Artificial Inteligence (AI-DOC). Welcome!
• Ambre Ayats joins the group as a YUFE postdoc. Welcome!
• How to mine redescriptions faster than before? Check out the new paper to appear at ECML PKDD!
• Ever wondered how a Boolean matrix factorization looks like? Wonder no more!
• How to mine differentially private redescriptions with a greedy algorithm? What about differentially private tree-based redescriptions? Check out our new papers!
• The 21st IEEE International Conference on Data Mining (ICDM) will be held in Auckland, NZ (or online) and the organisation is looking strong!
