Talk Title: "Prediction of Complex Systems Evolution Using Wireless Multi-Sensor Platforms: An Application to Sleep Apnea Mitigation"
Series: Epstein Institute Seminar Series
Abstract: Recent advances in wireless communications and sensing technologies are transforming quality and integrity assurance in real-world complex systemsâ⬔such as ultraprecision manufacturing and human cardiorespiratory processesâ⬔from a reactive detect-diagnose, to a proactive predict-prognose paradigm. Since much of the complexity in these real-world processes emerges from the underlying nonlinear nonstationary dynamics, approaches based on capturing this complexity from sensor signals are essential for their effective prediction and prognosis. Development of such approaches has been identified recently to be one of the ten modern scientific challenges.
This talk introduces a nonparametric Dirichlet process-Gaussian Mixture (DPGM) modeling approach to predict the evolution of process states based on tracking the local nonlinear dynamic topological characteristics underlying the measured signals. The approach is applied for real-time monitoring of a common cardiorespiratory disorder known as obstructive sleep apnea (OSA), which is found in 24% of adult males and 9% of adult females, and is considered a major risk factor for stroke and acute cardiorespiratory disorders. The current treatment methods, such as continuous positive airway pressure (CPAP) are not suitable to a majority of OSA patients. We developed a wearable wireless multisensory platform to continuously and noninvasively acquire physiological signals, and predict the nonlinear and nonstationary evolution of the coupled cardiorespiratory dynamics from the measured signal features using the DPGM model. Extensive tests employing recordings from the Physionet database and the wearable multisensory unit suggest that the present approach can predict an OSA episode 1 min ahead with an accuracy of 83%, and 3 min ahead with 77% accuracy. Such early detection can be used to adaptively adjust CPAP device airflow or the torso posture to avert major OSA episodes.

Mark Riedl (Georgia Tech): Intelligent Narrative Generation: Creativity, Engagement, and Cognition
Tue, Feb 19, 2013 @ 10:00 AM - 11:30 AM
Thomas Lord Department of Computer Science
Conferences, Lectures, & Seminars
Speaker: Mark Riedl , Georgia Tech
Talk Title: Intelligent Narrative Generation: Creativity, Engagement, and Cognition
Series: CS Colloquium
Abstract: Storytelling is a pervasive part of the human experience--we as humans tell stories to communicate, inform, entertain, and educate. Indeed there is evidence to suggest that narrative is a fundamental means by which we organize, understand, and explain the world. In this talk, I present research on artificial intelligence approaches to the generation of narrative structures using planning and case-based reasoning. I discuss how computational story generation capabilities facilitate the creation of engaging, interactive user experiences in virtual worlds, computer games, and training simulations. I conclude with an ongoing research effort toward generalized computational narrative intelligence in which a system learns from experiences mediated through crowdsourcing platforms.
Biography: Mark Riedl is an Assistant Professor in the Georgia Tech School of Interactive Computing and director of the Entertainment Intelligence Lab. Dr. Riedl's research focuses on the intersection of artificial intelligence, virtual worlds, and storytelling. The principle research question Dr. Riedl addresses through his research is: how can intelligent computational systems reason about and autonomously create engaging experiences for users of virtual worlds and computer games. Dr. Riedl earned a PhD degree in 2004 from North Carolina State University, where he developed intelligent systems for generating stories and managing interactive user experiences in computer games. From 2004 to 2007, Dr. Riedl was a Research Scientist at the University of Southern California Institute for Creative Technologies where he researched and developed interactive, narrative-based training systems. Dr. Riedl joined the Georgia Tech College of Computing in 2007 and in 2011 he received a DARPA Young Faculty Award for his work on artificial intelligence, narrative, and virtual worlds. His research is supported by the NSF, DARPA, the U.S. Army, and Disney.

Conferences, Lectures, & Seminars
Speaker: Dr. Vangelis Lympouridis, USC School of Cinematic Arts
Talk Title: Design and prototyping in Whole Body Interaction
Series: CS Colloquium
Abstract: The increasing interest in Whole Body Interaction (WBI) emerges in parallel with the development of new technologies for motion tracking, such as Microsoft's Kinect and a wide range of miniature inertial sensors, as well as a broader discussion on the design methodologies and the application of interactive systems in various contexts. WBI systems are expected to deliver meaningful digital responses based on the tracking and analysis of human actions. Body controlled applications need to be realized within a multidimensional design space and must operate through a wide spectrum of contexts. Artistic applications require a different design approach and an open ended collaboration schema for their realization. This presentation discusses various approaches and technologies for WBI design and prototyping in artistic, interactive entertainment and health application contexts.
Biography: Dr. Vangelis Lympouridis is a visiting scholar at USC's School of Cinematic Arts and works for the Creative Media & Behavioral Health Center within the Interactive Media Division.

Talk Title: Novel Bioelectrochemical Systems for Water and Wastewater Treatment
Abstract: As an emerging concept, bioelectrochemical systems (BES) have gained significant attention because of their integrated wastewater treatment and bioenergy recovery. The representatives of BES include microbial fuel cells (MFCs), microbial electrolysis cells (MECs) and microbial desalination cells (MDCs). BES takes advantage of microbial metabolism and electrochemical reactions to oxidize organic compounds and generate electrons that can be extracted as electric energy. This energy can be used either to offset the energy consumption by wastewater treatment, or to drive desalination through integrating drinking water treatment with wastewater treatment. The potential for BES to disrupt current water/wastewater treatment processes is significantâ⬔the treatment plants in the U.S. currently consume a large amount of electricity, whose production requires coal and other heavy-polluting fossil fuels. As a result, the negative effects of energy production on the environment combined with ever-increasing demands for clean water and energy are depleting natureââ¬â¢s resources and ultimately affecting human health. BES offer great promise for treating wastewater and/or desalinating saline water in a more energy-efficient way, and can potentially function as an alternative to todayââ¬â¢s treatment processes. However, the current state of BES for practical application is far from readyâ⬔they still possess challenges that limit their application in treating wastewater/water and producing bioenergy, which require intensive and strategic exploration. This presentation will introduce and discuss two potential applications of BES, bioelectrochemical wastewater treatment and bioelectrochemical desalination, and the key issues/challenges of their research and development. The section ââ¬Åbioelectrochemical wastewater treatmentââ¬Â will focus on MFC configuration, system scaling up, electrochemical limitation, microbial community on electrodes, and electrode modification using carbon nanomaterials. Bioelectrochemical desalination will introduce MDC development. Analysis of energy production, transfer and use in MDCs suggests that MDCs should be operated under a high-current condition. To reduce salinity through dilution by extracting useful water from wastewater, forward osmosis is integrated into MFCs to form osmotic MFCs (OsMFCs). We have hydraulically coupled OsMFCs with MDCs and achieved improved treatment of both wastewater and seawater.

Talk Title: Robust and Efficient Real-time Mapping for Autonomous Robots
Series: CS Colloquium
Abstract: We are starting to see the emergence of autonomous robots that operate outside of controlled factory environments in various applications ranging from driverless cars, space and underwater exploration to service robots for businesses and homes. One of the very first challenges encountered on the way to autonomy is perception: obtaining information about the environment that allows the robot to efficiently navigate through, interact with and manipulate it. Moreover, in many such applications, models of the environment are either unavailable or outdated, thus necessitating real-time robotic mapping using onboard sensors.
In this talk I will present my recent research on efficient optimization techniques for robotic mapping, and in particular focus on the recently developed incremental nonlinear least-squares solver, termed incremental smoothing and mapping (iSAM2). Based on our new probabilistic model called the Bayes tree, iSAM2 efficiently updates an existing solution to a least-squares problem after new measurements are added. I will describe some of the key aspects of my work and also address robustness in optimization. Lastly, I will present applications enabled by iSAM2 including our long-term visual mapping and Kintinuous -- our recent work on dense mapping with RGB-D cameras.
Biography: Michael Kaess is a Research Scientist in the Computer Science and Artificial Intelligence Laboratory (CSAIL) at the Massachusetts Institute of Technology (MIT), where he previously also was a Postdoctoral Associate. He received the Ph.D. and M.S. degrees in computer science from the Georgia Institute of Technology in 2008 and 2002, respectively. His research focuses on probabilistic methods for robot perception. He was one of the two runner-ups for the 2012 Volz dissertation award for the best U.S. Ph.D. thesis in robotics and automation that takes into account impact four years after publication.

Truth in Interactive Storytelling An Evening with Artist-Writer Phoebe Gloeckner
Tue, Feb 19, 2013 @ 07:00 PM - 08:30 PM
USC Viterbi School of Engineering
University Calendar
Admission is free.
Reception to follow.
Phoebe Gloeckner is best known as the author of groundbreaking comics stories about young girls in early-1970s San Francisco. Her comics have appeared in legendary underground publications like Weirdo and Wimmenâs Comix as well as in book-length collections, drawing accolades from popular and scholarly audiences. During the last decade, Gloeckner has been experimenting with new content and new media, performing intensive research in and creating multimedia artworks about the border city of Ciudad Juárez, where, amidst larger waves of political, economic and drug-related violence, thousands of girls and women have been murdered or gone missing. Gloeckner will present portions of the new project, in which she recreates Juárez-based streetscapes, domestic spaces, crime scenes and prison cells in a series of scale-model environments populated by digitally manipulated dolls with which the viewer can interact. Gloecknerâs exploration of the relationship between fact and fiction, between digital and physical media, and between art and activism, represents an important response to the violence in Juárez, while raising questions about the role of artists in investigating politically charged issues.
Phoebe Gloecknerâs collection of comics A Childâs Life and Other Stories comprised a gathering of her earlier work and was followed by The Diary of a Teenage Girl. Gloeckner has produced illustrations and cover images for volumes in the RE/Search series (Angry Women,The Atrocity Exhibition and Dangerous Drawings) and for childrenâs books, including Weird Things You Can Grow. In 2003, Utne Reader listed Gloeckner among âForty Artists Who Will Shake the World.â A medical illustrator as well as a writer and artist, Gloeckner provided drawings for Embryogenesis: Species, Gender, and Identity and for the third edition of The Good Vibrations Guide to Sex. Gloeckner is on the faculty of the School of Art and Design at the University of Michigan. She received a Guggenheim Fellowship in support of her Ciudad Juárez project.
Organized by Alice Gambrell (English).
