DANIEL J. EPSTEIN DEPARTMENT OF INDUSTRIAL AND SYSTEMS ENGINEERING Presents"Not Your Grandmother's Genetic Algorithm"Dr. David E. GoldbergJerry S. Dobrovolny Distinguished Professor in Entrepreneurial Engineering, University of Illinois at Urbana-ChampaignABSTRACT: Genetic algorithms (GAs)--search procedures inspired by the mechanics of natural selection and genetics--have been increasingly applied across the spectrum of human endeavor, but some researchers mistakenly think of them as slow, unreliable, and without much theoretical support. This talk briefly introduces GAs, but quickly shifts to a line of work that has succeeded in supporting GA mechanics with bounding design theory that has been used to demonstrate GA scalability, speed, and range of reliable applicability. Key elements of this theory are discussed to give insight into this accomplishment and to make the point that fast, scalable GAs may also be viewed as first-order models of human innovative or inventive processes. The talk highlights recent results in breaking the billion-variable optimization barrier for the first time. It also discusses recent experience with GA-inspired creativity or innovation support systems.THURSDAY, NOVEMBER 29, 2007, 11:00 AM – 12:00 PM, ANDRUS GERONTOLOGY BLDG (GER) 309-------------------------------BIOGRAPHY: David E. Goldberg, a leader in the field of genetic algorithms, is the Jerry S. Dobrovolny Distinguished Professor in Entrepreneurial Engineering at the University of Illinois at Urbana-Champaign. He is also co-founder and chief scientist of Nextumi, Inc., a web2.0 startup company. Trained as a civil engineer at the University of Michigan, where he earned his B.S.E. and took his Ph.D. in 1983, Dr. Goldberg has held positions at Michigan, Alabama, and Illinois. The founding chair of the International Society for Genetic and Evolutionary Computation, he is co-chair of the inaugural Workshop on Philosophy and Engineering held at TUDelft, and he co-founded the initiative on Engineering and Technology Studies at Illinois (ETSI). Among many honors, he is the recipient of a National Science Foundation Presidential Young Investigator Award, a Wickenden Award presented by the American Society for Engineering Education, and an Outstanding Instructor Award presented by the National Technological University. In addition to articles in professional journals, he is the author of two books on genetic algorithms, the widely-cited Genetic Algorithms in Search, Organization, and Machine Learning (1989) and The Design of Innovation (2002), and, most recently, The Entrepreneurial Engineer, which was published in 2006 by Wiley.

CS Colloquia: Partitioned and Hybrid Methods for Visual Servo Control

Title: Partitioned and Hybrid Methods for Visual Servo ControlSpeaker: Prof. Seth Hutchinson(UIUC)ABSTRACT:
Visual servo control concerns the problem of controlling robots using
real-time computer vision feedback. While numerous approaches have
evolved, and many systems have been demonstrated in laboratories around
the world, most can be classified as either position-based or image-based,
depending on whether camera pose or image features are used in the control
law. Each approach has well-documented performance problems.In this talk, after a brief description of these methods and their
respective shortcomings, I will describe two approaches to overcoming
their performance problems. With the first approach, the control system
is partitioned along its spatial degrees of freedom. Rotation about and
translation along the optical axis are controlled by a specifically
designed controller, and the remaining degrees of freedom are controlled
with a traditional image-based method. With the second approach, a
hybrid, switched control system selects either an image-based or
position-based controller at each time instant, using a state-based
switching scheme. The performance of both of these approaches have been
verified by a variety of simulated and experimental results. If time
permits, I will also describe recent results applying a switched method to
the control of a unicycle robot with field-of-view constraints.BIO:
Seth Hutchinson received his Ph.D. from Purdue University in 1988. In
1990 he joined the faculty at the University of Illinois in
Urbana-Champaign, where he is currently a Professor in the Department of
Electrical and Computer Engineering, the Coordinated Science Laboratory,
and the Beckman Institute for Advanced Science and Technology. Dr.
Hutchinson serves as the Editor-in-Chief for the RAS Conference Editorial
Board, and on the editorial boards of the International Journal of
Robotics Research and the Journal of Intelligent Service Robotics. He
served as Associate and then Senior Editor for the IEEE Transactions on
Robotics and Automation, now the IEEE Transactions on Robotics, from
1997-2005. In 1996 he was a guest editor for a special section of the
Transactions devoted to the topic of visual servo control, and in 1994 he
was co-chair of an IEEE Workshop on Visual Servoing. In 1996 and 1998 he
co-authored papers that were finalists for the King-Sun Fu Memorial Best
Transactions Paper Award. He was co-chair of IEEE Robotics and Automation
Society Technical Committee on Computer and Robot Vision from 1992 to
1996, and has served on the program committees for more than fifty
conferences related to robotics and computer vision. He has published
more than 150 papers on the topics of robotics and computer vision, and is
coauthor of the books 'Principles of Robot Motion: Theory, Algorithms, and
Implementations', published by MIT Press, and 'Robot Modeling and
Control', published by Wiley.Location: Seaver Science Library (SSL) - 150
