Time: 4 PM - 5 PMLocation: SSL 150Talk title: Robotic Exoskeletons for Gait Assistance and Training of the Motor Impaired
Speaker: Prof. Sunil K. Agrawal (University of Delaware)
Host: Prof. Gaurav S. SukhatmeAbstract:
Robotics is emerging as a promising tool for training of human functional movements. The talk will describe novel designs of lower extremity exoskeletons, intended for gait assistance and training of motor-impaired patients. The exoskeletons have undergone tests on healthy and chronic stroke survivors to assess their potential. GBO is a Gravity Balancing un-motorized Orthosis which can alter the gravity acting at the hip and knee joints during swing. ALEX is an Actively driven Leg Exoskeleton which can modulate the foot trajectory using motors at the joints. This research was supported by NIH through a BRP program.

Talk title: Inference in Large-Scale Graphical Models and its application to SFM, SAM, and SLAMSpeaker: Prof. Frank Dellaert (Georgia Tech)Host: Prof. Gaurav S. SukhatmeAbstract:
Simultaneous Localization and Mapping (SLAM), Smoothing and Mapping (SAM), and Structure from Motion (SFM) are important and closely related problems in robotics and vision. Not surprisingly, there is a large literature describing solutions to each problem, and more and more connections are established between the two fields. At the same time, robotics and vision researchers alike are becoming increasingly familiar with the power of graphical models as a language in which to represent inference problems. In this talk I will show how SFM, SAM, and SLAM can be posed in terms of this graphical model language, and how inference in them can be explained in a purely graphical manner via the concept of variable elimination. I will then present a new way of looking at inference that is equivalent to the junction tree algorithm yet is - in my view- much more insightful. I will also show that, when applied to linear(ized) Gaussian problems, the lgorithm yields the familiar QR and Cholesky factorization algorithms, and that this connection with linear algebra leads to strategies for very fast inference in arbitrary graphs. I will conclude by showing some published and preliminary work that exploits this connection to the fullest.Bio:
Frank Dellaert is an Associate Professor in the School of Interactive Computing, College of Computing at Georgia Tech. His research is in the areas of Robotics and Computer vision. He is particularly interested in graphical model techniques to solve large-scale problems in mapping and 3D reconstruction.

CS Colloq: Dr. K L. Bellman

Time: 4:00 PM - 5:30 PMLocation: SSL 150Talk title: To be announced
Speaker: Dr. Kirstie L. Bellman, Principal Scientist, The Aerospace Corporation
Host: Prof. Ari RequichaAbstract:
The purpose of this talk is to stimulate a discussion about the architectural requirements for complex adaptive systems, as well as to broaden our definitions of "architecture."
Our ability to engineer large complex systems has been greatly impacted by the open, de facto information, computational, and device architectures that are springing up (e.g. Web, Internet, GIG, GRID computing, swarms of robots or UAVs, "internet of things" etc.) These architectures are characterized by a dynamic, constant insertion of new information sources and computational or device capabilities and by diverse users, stakeholders, viewpoints and goals. One implication of the above is that it may be infeasible to design and control large-scale complex adaptive systems in the top-down, heavy-handed, developer-driven style of yesterday. Complexity and scale are now forcing on system engineering, what has always been known in space systems because of distance and time lag: One cannot control quickly or accurately enough the complex system; it must help us to monitor, control, and manage itself. Recently Organic Computing in Europe and other movements have argued that the complexity requires the help of the system to co-design and indeed co-develop itself.
In our work, a key component of enabling such abilities has been "computational reflection" or the ability of a system to explicitly reason about its own goals, resources, activities, and relationship to its operational environment. In this talk, we will introduce several important concepts in engineering complex adaptive systems, define a reflective architecture, and briefly discuss our approach to implementing reflection, based on the wrappings approach.
We then discuss how all of the above changes the concept of ?architecture? as a compact description of a fixed configuration of components and relationships to "meta-architectures". That is, given such characteristics as the ability to insert new system components, system processes, and system configurations and dynamically determine context-sensitive relationships and configurations, one may well ask: what is invariant in an architecture? In the case of Wrappings applications, the invariant is the meta-architecture: The roles and purposes of the reflective processes and system level processes remain the same, regardless of application domain, domain resources, and the implementation of the reflective processes. As time permits we will discuss some early work to develop a reflective architecture for an Organic Computing chip design application with German colleagues.BIO:
