CSGO Research Seminar
---------------------
CSGO, the Computer Science Graduate Organization,
sponsors seminars to bring together students and
researchers in the areas of Computer Science and
Engineering, introducing the students to the
researchers and providing a chance for the
researchers to get to know the students.
Some of the talks during the semester will be given
by senior Ph.D students.
There will be one seminar every week of approximately
one hour duration followed by a question and answer
session.
The seminar is at 10:00 a.m. every Tuesday morning
in SAL 324.
Next week the seminar will be:

ABSTRACT
--------
This talk will present work that I have done with Michael
Arbib on modeling the behavior and neural activity in
premotor cortex of monkeys learning to pair an arbitrary
visual stimulus with one of a set of previously-learned
motor responses. The network model is comprised of a
large number of "motor selection columns." Reinforcement
learning is used to tune the sensitivity of these columns
so that they learn to recognize relevant visual features
and produce support for the the appropriate motor
response. Although each column is allowed only limited
information a set of columns are able to work together
to learn a single visual-motor mapping.
This model has been successful in reproducing a number of
key behavioral and neurophysiological observations. We
will present a number of predictions for new experimental
outcomes and will also show how recent data may be used
to make a number of modifications to the model.
Finally, recent work will be discussed briefly which
attempts to extend this model in two different directions:
first, by adding a temporal component to the generation
of output, and second, by beginning to think about how the
monkeys might learn how to perform the task in the first
place. This work will then be related to learning in
robots.
