**O.Univ.-Prof. Dr. Wolfgang Maass**

Office hours: by appointment (via e-mail)

E-mail: maass@igi.tugraz.at

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

Location: IGI-seminar room, Inffeldgasse 16b/I, 8010 Graz

Date: starting on 2nd of March 2011, 4.15 p.m.

In addition talks
can be presented on the following material, that is closely
related to research projects at our Institute. Some of these
topics could also serve as first step towards a Master project
or -thesis.

The remaining slots for talks (two 40-minute talks at each
seminar meeting) will be assigned at the Organization meeting on
march 2.

If you are particularly interested in a particular one of these
topics (or want to propose an additional one) you can also send
anytime email to Wolfgang Maass.

--Marc Toussaint: Approximate inference control
(preprint),

[outlines a promising approach for solving motor control tasks
via Bayesian networks, shows that stochastic optimal control is
a special case of this approach, an MA-thesis in this direction
could complement already ongoing work in this direction at IGI]

[very interesting new approach involving both probabilistic
inference and relational rules; an MA-thesis in this direction
could complement already ongoing work in this direction at IGI ]

--SJ Gershman, Y Niv: Learning latent structure: carving nature
at its joints, Current Opinion in Neurobiology, 2010 http://www.princeton.edu/~sjgershm/GershmanNiv10.pdf

[This paper provides very important new ideas for robot learning
etc, exploiting learning simultaneously on several layers of
abstraction, on which we will work at our Institute; the paper
itself review primarily related evidence from biological motor
control. In conjunction with some cited papers this review paper
would also provide material for more than 1 talk. This paper
would provide a good basis for a MA-thesis on the development of
methods for fast robot learning.]

[This paper provides the main background for a potential
MA-thesis (supervised by Dr. Legenstein). MA thesis short
description: "Self-organization of task-dependent computation in
sensory circuits". Results from Li, Piech, and Gilbert (2004)
show that neurons in primary visual cortex can drastically and
rapidly change their feature preferences in dependence of the
currently performed task. This ability suggests that sensory
cortical areas act as adaptive processors, performing different
calculations according to the immediate perceptual demands
(Gilbert et al. 2009). Such complex neuronal behavior is
probably a result of local neural circuits that exploit
nonlinear dendritic properties of single neurons as well as
feedback from other cortical areas. This MA thesis will explore
how feedback indicating the current task can influence the
computation of local circuits of spiking neurons and how the
computation can be self-organized through synaptic plasticity
mechanisms.
