Seminar Computational Intelligence E (708.115)
Applications of Machine
Learning in Neurobiology
Grundlagen der Informationsverarbeitung (708)
Lecturer: O.Univ.-Prof. Dr. Wolfgang Maass
Office hours: by appointment (via e-mail)
Location: IGI-seminar room,
Inffeldgasse 16b/I, 8010 Graz
Date: Wednesday, 16:15-18:15 p.m.
starting on March 7, 2007 (organization meeting; you can also reserve a
talk by sending email to firstname.lastname@example.org
Content of the seminar:
We will discuss in this seminar the application of advanced methods
from machine learning and data mining (pattern classification,
feature extraction, clustering)
in order to detect patterns (e.g. "neural codes") in high-dimensional
time series as they emerge from various types of multi-unit recordings
in neurobiology (spike trains, local field potential, EEG).
We will focus on a few concrete study cases where our institute is
involved in the analysis of data from neurobiology, and will examine
the performance of various methods.
The available data and algorithms will be brought into a common format,
so that it will be easy to compare the performance of different
In addition we will have talks on some new approaches for pattern
recognition and feature extraction in machine learning, that promise to
provide improved performance.
The talks in this seminar can also serve as preparation for a project
or master thesis on applied machine learning.
Each talk will have a lengt of 40 minutes (in order to serve also as an
opportunity to extract and descibe the
most salient aspects of a paper).
Those among the papers listed below that are not publicly available,
can be found in our pdf-archive (students who are not working at our
institute can get a
copy from Angelika Zehetner email@example.com)
Tentative topics for talks
At our organization meeting we came up with the following plan:
Later in March (to be announced): Michael Pfeiffer and Martin Ebner
will talk about their analysis of the Cricket data from the KFU-team;
and Dr Hartbauer from the KFU will present details of these data.
21.05.2007 Michael Pfeiffer and Gregor Hoerzer:
Clustering (spectral clustering, and message-passing clustering)
23.05.2007 Martin Ebner
Methods developed for BCIs in Berlin, which may be relevant
for our data (in particular analysis of LFPs).
06.06.2007 (16.15 p.m.) Klaus Schuch
Sparse Bayesian Learning and Relevance Vector Machine
28.06.2007 (16.15 p.m.) Dejan Pecevski
Nonlinear feature selection with PSVM
28.06.2007 Stefan Klampfl
Methods for estimating mutual information developed by Stefano Panzeri
Remains to be scheduled:
