General information

Dr. Juha Karhunen is Professor of Computer Science (currently working 75% of yearly full time, specification area: Neural networks and signal processing) in the Aalto University School of Science (in Finnish: Aalto yliopisto, Perustieteiden korkeakoulu), located near Helsinki in Espoo, Finland. The Aalto University was formed on 1st January 2010 by merging Helsinki Univ. of Technology (HUT) with two smaller universities.

Juha Karhunen worked up to the end of the year 2014 in the Department of Information and Computer Science. In January 2015, our department was merged with the Department of Media Technology and Department of Computer Science and Engineering, forming the new Department of Computer Science. This is the biggest department in Aalto University, having about 40 professors and personnel of about 400 people. The home pages of this new department are currently under construction.

Curriculum vitae
A complete List of publications. See the 'Publications' subpage for publications available in electronic form.


I have belonged to five research groups in the Department of Computer Science. For more information on these research groups and their activities, please go to my 'Research' subpage. My main research group is currently Applications of Machine Learning. Assistant Prof. Tapani Raiko is now responsible for my old research group which changed its name a couple of years ago to Deep Learning and Bayesian Modeling. My last researcher in this group is being moved under Tapani Raiko's supervision. Furthermore, I am the supervising professor and formal head of two research groups, Computational Methods and Data Analysis for Astrophysics, and Content-Based Image and Information Retrieval. Drs. Maarit Käpylä (earlier Mantere) and Jorma Laaksonen are respectively leading the daily activities of these two research groups. Furthermore, I belong to the research group on Independent component analysis and blind source separation which was led by distinguished professor Erkki Oja. He retired in February 2015. This research group is historically important but now it has little activity.

My tasks in these research groups include guiding doctoral and Master's (Dipl. Eng.) theses, making administational decisions, acquiring financial support and project funding, attending project meetings, organizing group meetings, and participating in writing selected papers. More generally, one of my most important research related tasks consists of reviewing of papers submitted to journals and conferences in which I am often a member of the program committee.

Lecture or seminar courses at HUT and Aalto University

- Lecture course Machine Learning and Neural Networks. I have lectured this course for the first time in November-December 2007, and then yearly at the same time. In this autumn I renewed this course, which belongs to our department's international Macadamia (Machine learning and data mining) M.Sc. study programme.

Graduate courses on varying topics:
- In spring 2009, a seminar course on Nature-Inspired Computing
- In spring 2006, a lecture course on Independent Component Analysis.
- In spring 2004, a seminar course on Information Theory and Machine Learning.
- In spring 2003, a seminar course on Support Vector Machines and Kernel Methods.
