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.

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
, and Content-Based Image and
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
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
(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
- In spring 2004, a seminar course on
and Machine Learning.
- In spring 2003, a seminar course on
Machines and Kernel Methods.
