I am retiring, and will not accept any new people under
Dr. Juha Karhunen is Professor of Computer Science (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, namely Helsinki Univ.
of Economics, and Univ. of Art and Design. They are now their own schools
in Aalto University, while HUT has been divided in Aalto into four schools.
Juha Karhunen worked up to the end of the year 2014 in the Department of
Information and Computer Science. In January 2015, this 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 more
than 40 professors and personnel of about 400 people.

A complete List of publications

subpage for publications available in electronic form.
I have belonged to five research groups in the Department of Computer Science
and its predecessors. 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
My old research group changed its name three years ago from Bayesian Latent
Variable Modeling to Deep Learning
and Bayesian Modeling
. This research group was under Assistant Prof. Tapani
Raiko's supervision until he moved to work in Apple Corp. in August 2016. Furthermore,
I was until recently the supervising professor and formal head of two other research
groups, Computational Methods and Data
Analysis for Astrophysics
Content-Based Image and Information
. Drs. Maarit Käpylä (earlier Mantere) and Jorma Laaksonen are
respectively leading the daily activities of these two research groups. Their new
supervising professors are respectively Aki Vehtari and Samuel Kaski. I have belonged
a long time to the research group on
Independent component analysis and blind
which was led by distinguished professor Erkki Oja, who
retired in February 2015. This research group is historically important, but
it is no longer active.
My tasks in these research groups have included 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. I have renewed
this course, which belongs to our department's international
learning and data mining)
M.Sc. study programme. In autumn 2017, the topic of this
course will be changed to deep learning, and its new lecturer will be Dr. Jyri Kivinen.
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.
