Principles Underlying the Construction of Brain-Based Devices
Thursday, May 18, 2006
6:30 P.M. - 8:00 P.M.
Join your colleagues at the next meeting of The San Diego Chapter of
the Association for Computing Machinery (ACM), featuring Jeff Krichmar
who is a research fellow at The Neurosciences Institute in San Diego
where he is currently a Senior Fellow in Theoretical Neurobiology.
Jeff is the lead designer for Nomad, a soccer playing robot built on a
Segway platform.
There will be light snacks and great door prizes ... please reserve
your seat (see below) before it's too late!
We will meet at 6:30PM at The Neurosciences Institute, 10640 John Jay
Hopkins Drive, San Diego in the UCSD area. The meeting cost is
$3 for reservations paid in advance via PayPal
or $5 at the door -- free for chapter members.
The meeting is open to the public. For more information, call
(858) 452-8701 or visit http://www.sdacm.org .
(We are also pleased to acknowledge the generous support of Sun
Microsystems.)
Bring your colleagues and friends -- we hope to see you there!

Abstract:
Without a doubt the most sophisticated behavior seen in biological
agents is demonstrated by organisms whose behavior is guided by a
nervous system. Thus, the construction of behaving devices based on
principles of nervous systems may have much to offer. Our group has
built series of brain-based devices (BBDs) over the last 15 years to
provide a heuristic for studying brain function by embedding
neurobiological principles on a physical platform capable of
interacting with the real world. These BBDs have been used to study
perception, operant conditioning, episodic and spatial memory, and
motor control through the simulation of brain regions such as the
visual cortex, the dopaminergic reward system, the hippocampus, and
the cerebellum. Following the brain-based model, we argue that an
intelligent machine should be constrained by the following design
principles: (i) it should incorporate a simulated brain with detailed
neuroanatomy and neural dynamics that controls behavior and shapes
memory, (ii) it should organize the unlabeled signals it receives from
the environment into categories without a priori knowledge or
instruction, (iii) it should have a physical instantiation, which
allows for active sensing and autonomous movement in the environment,
(iv) it should engage in a task that is initially constrained by
minimal set of innate behaviors or reflexes, (v) it should have a
means to adapt the device's behavior, called value systems, when an
important environmental event occurs, and (vi) it should allow
comparisons with experimental data acquired from animal nervous
systems. Like the brain, these devices operate according to
selectional principles through which they form categorical memory,
associate categories with innate value, and adapt to the environment.
Moreover, this approach may provide the groundwork for the development
of intelligent machines that follow neurobiological rather than
computational principles in their construction.
Presenter Bio:
Jeffrey L. Krichmar received a B.S. in Computer Science in 1983 from
the University of Massachusetts at Amherst, a M.S. in Computer
Science from The George Washington University in 1991, and a Ph.D. in
Computational Sciences and Informatics from George Mason University in
1997. Dr. Krichmar spent 15 years as a software engineer on projects
ranging from the PATRIOT Missile System at the Raytheon Corporation to
Air Traffic Control for the Federal Systems Division of IBM. In 1997,
he became an assistant professor at The Krasnow Institute for Advanced
Study at George Mason University. In 1999, he became a research
fellow at The Neurosciences Institute in San Diego where he is
currently a Senior Fellow in Theoretical Neurobiology at The
Neurosciences Institute. His research interests include biologically
plausible models of learning and memory, the effect of neural
architecture on neural function, and testing theories of the nervous
system with Brain-Based Devices that interact with the environment.
Dr. Krichmar and his colleagues at The Neurosciences Institute have
successfully constructed Brain Based Devices, robotic devices whose
behavior is controlled by a simulated nervous system, to test theories
of the nervous system having to do with perceptual categorization,
primary and secondary conditioning, visual binding, motor control, and
memory. A recent article describing The Neurosciences Institute's
Brain-Based Device laboratory was featured in New Scientist magazine
(November 2005). Dr. Krichmar is author of approximately 40
scientific articles, has organized international conferences on
brain-based robotics, and chair of a new Robotic Soccer league which
involves Segway robots interacting with humans.
Meeting Charge
The meeting costs $5 payable at the door or $3
payable via advanced reservation using our reservations and
payment form at -- chapter
members get in free. (You can save approximately 50% by purchasing an
annual SDACM Membership at the door for only $12 -- or $10 using the
reservations and payment form -- see membership policy for
more details.)
RSVP Policy
We strongly encourage you to let us know if you plan to
attend this meeting. We expect this meeting to be very well attended,
and we may run out of space. In that case, attendees with
reservations will be given admittance and seating preference. See
RSVP policy for more details.
Location
The Neurosciences Institute

Directions
From Interstate 5, exit at Genesee Avenue and go west for
about 0.8 mile to the second stoplight (not counting any at the I-5
exit). Turn right (north) onto John Jay Hopkins Drive. Turn left at
the second opportunity (about 0.1 mile) into the Institute's driveway.
(The first opportunity to turn left is into an obviously gated parking
lot. If the gates are raised, you may park in that lot.) In the
driveway, bear right into the Visitor Parking area. Walk across the
central plaza to the three-story building at the north end.
Free parking anywhere.
