Lyhyt esittely suomeksi:
Hannu Toivonen on tietojenkäsittelytieteen professori Helsingin yliopistossa. Hän on tutkinut tekoälyä vuodesta 1990, professorina vuodesta 2002. Hän julkaissut yli 200 tieteellistä artikkelia, joihin on viitattu yli 27000 kertaa. Hän on ohjannut yli 20 väitöskirjaa ja hänellä on 10 patenttia. Hannu on toiminut myös laitoksen johtajana, tiedekunnan varadekaanina ja tohtorikoulun johtajana.
Tieteellisen tutkimuksen lisäksi Hannu on kehittänyt tekoälyn sovelluksia muille tieteenaloille (esim. genetiikka, ekologia, paleoekologia, bioinformatiikka) sekä luoviin tehtäviin (esim. kuunnelman, runojen ja musiikin tuottamiseen). Vuonna 2023 hän julkaisi helppolukuisen tietokirjan Mitä tekoäly on? 100 kysymystä ja vastausta (Teos), ja on sen jälkeen pitänyt yleistajuisia esityksiä tekoälystä kaikenlaisille yleisöille. Hänet on valittu 100 suomalaisen IT-vaikuttajan joukkoon.
I am an AI researcher and Professor of Computer Science at the Department of Computer Science of the University of Helsinki. During spring 2025, I am visiting Belgium as Francqui International Professor and VUB as Visiting Professor. At the University of Helsinki, I lead the Discovery Research Group, and I'm affiliated with HIIT and FCAI. I teach in Computer Science BSc and MSc programmes, in Data Science MSc programme, and I'm involved in establishing a new Liberal Arts & Sciences BSc programme.
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. In 2025, he visits VUB and four other Belgian universities as International Francqui Professor; year 2006 he spent at the University of Freiburg, Germany.
Hannu Toivonen has over 200 international refereed publications. According to Google Scholar, he has been cited over 27,000 times and he has an h-index over 60. 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. Prof. Toivonen has served as Editorial Board member of the leading journals and as Senior Programme Committee positions of the leading conferences in his research areas.
Hannu Toivonen was Vice-Dean of Academic Affairs of the Faculty of Science for 2018-21 (21 degree programmes, 6000 students), Head of the Department of Computer Science for 2007-9 (170 FTE staff), director of the Helsinki Doctoral Programme in Computer Science for 2007-11 (80 PhD students) and founding director of the Data Science MSc programme for 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.
Since 2023, popularization of AI has been in Prof. Toivonen's focus. He published an accessible book "Mitä tekoäly on?" (What is AI?) in Finnish, with the aim of helping citizens understand and discuss AI and its implications in their lives. Swedish and German editions of his book are in the works. Prof. Toivonen also is a frequent public speaker, explaining AI in simple terms to various audiences.
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.
My publications are mainly in the areas of artificial intelligence, computational creativity, data mining and data science, and cover both their theory and their applications in numerous fields. According to Google Scholar, my work has been cited over 27000 times.
I'm the author of a best-selling Finnish non-fiction book on AI, "Mitä tekoäly on? 100 kysymystä ja vastausta" ("What is AI?").
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 TV and radio and Finnish press. The most recent public media appearances are listed below.
Miscallaneous scientific activities, e.g., international programme committee membership.
My visits to misc. podcasts, in Finnish and in English
My work on computational creativity also aims at producing creative systems and artistic results.
