Hannu Toivonen
Prof. Hannu "Haba" Toivonen works in the areas of artificial intelligence and data science, more specifically in computational creativity and data mining. His current research focus is on using data science for computational creativity, on self-aware and creative systems, and on analysis and generation of natural language.
Academic profile & affiliations

I am an AI researcher and Professor of Computer Science at the Department of Computer Science of the University of Helsinki.  I lead the Discovery Research Group, and I'm affiliated with HIIT and FCAI. I teach in the Data Science MSc programme and Computer Science MSc and BSc programmes.

Biography

Professor Hannu Toivonen is a leading expert in data mining and computational creativity. He has introduced and solved several novel research problems in the area of data mining since the field was born in early 1990s; his definitions and algorithms have become standard references and textbook material in the field. He has since developed applications of data mining for gene mapping, context-aware computation, document analysis and summarization, computational creativity, and natural language generation.

Hannu Toivonen obtained his PhD in Computer Science in 1996 and has been Full Professor at the University of Helsinki since 2002. Hannu Toivonen was Vice-Dean of Academic Affairs of the Faculty of Science during 2018-21 (21 degree programmes, 6000 students), Head of the Department of Computer Science during 2007-9 (170 FTE staff), director of the Helsinki Doctoral Programme in Computer Science during 2007-11 (80 PhD students) and founding director of the Data Science MSc programme during 2016-2018. He has secured external funding for over 7 MEUR, including five EU projects and numerous domestic projects. Prof. Toivonen also has six years of industrial experience from Nokia Research Centre. He holds ten patents.

Hannu Toivonen has over 200 international refereed publications. According to Google Scholar, he has been cited 25,000 times and he has an h-index of 57. He served as Programme Chair of IEEE ICDM 2014, a leading data mining conference, of ICCC 2015, the International Conference on Computational Creativity, and of the AI, Arts & Creativity special track of IJCAI 2022. He is Editorial Board member of the leading journals and a regular Senior Programme Committee member of the leading conferences in his research areas.

Hannu Toivonen has been decorated as Knight, First Class, of the Order of the White Rose of Finland. He is a member of the Finnish Academy of Science and Letters and of the Finnish Academy of Technical Sciences. He is also a honorary member of the computer science student association TKO-äly ry.

Recent Publications

My publications are mainly in the areas of artificial intelligence, computational creativity, data mining, data science and natural language engineering, and cover both theory and applications.

Research Projects

My research methodology consists of identification of relevant computational problems, development of new concepts and algorithms for them, and of building systems and applying the algorithms. Recent projects concern analysis of text and generation of text, self-awareness and creative self-adaptivity.

Other scientific activities
Art

For artistic projects (radio play, poems, music, installations, rap, images etc.) see Art-related work by the Discovery Group.

My work on computational creativity also aims at producing creative systems and even artistic results. Please see my research group's Art page for artistic results of the group.

Press and media

My work has been covered by international media such as MIT Technology Review, Wired, Deutsche Welle, New Scientist, The Wall Street Journal, CNET, CBC as well as Finnish YLE, Nelonen and HS. See here for additional links.
