Homepage: www.igi.tugraz.at/maass/



Location: IGI-seminar room, Inffeldgasse 16b/I, 8010 Graz
Date: Thursday, 16:15-18:15 p.m.
starting on October 9th, 2008 (organization meeting; you can also reserve a talk by sending email to maass@igi.tugraz.at )


Content of the seminar:

New Research Results in Computational Neuroscience, Gene Regulation Networks and Machine Learning.

We will discuss new publications in these areas. Several of the topics are chosen so that they are also accessible by master students with no prior research experience, and may provide inspiration and material for master projects and theses. For new students it is recommended that they simultaneously attend the course

Remark: Several of the topics of this seminar are related to the 4-year EU-project SECO (Self-Constructing Circuits)
http://www.seco-project.eu/
that has started in April of this year.
