EMOTIONAL INTELLIGENCE TECHNOLOGY AND AUTISM

Rosalind Picard, Director of the Affective Computing Group and Autism and Communication Technology Initiative, Massachusetts Institute of Technology

Abstract: Skills of emotional intelligence include the ability to recognize and respond appropriately to another person’s emotion, and the ability to know when (not) to display emotion. This talk will demonstrate advances at MIT aimed at giving several of these skills to technology, including mobile devices, robots, agents, and wearable and traditional computers. I will present live demonstrations of current technology, including a system developed with Rana el Kaliouby to recognize cognitive-affective states in real-time from a person’s head and facial movements. This technology computes probabilities that a person looks like he or she is concentrating, interested, agreeing, disagreeing, confused, or thinking. These states signal important information such as when is a good time to interrupt, or when it might be appropriate to apologize for interrupting.  A wearable version of this system is being developed for helping people who face challenges in reading real-time social-emotional cues.  I will describe several other new affective technologies that facilitate emotion measurement and communication, and describe applications in autism.

Speaker biography: Rosalind Picard is founder and director of the Affective Computing Research Group, and co-founder and director of the Autism and Communication Technology Initiative at the MIT Media Laboratory. After receiving a bachelor’s degree in electrical engineering with highest honors from Georgia Tech, Picard joined AT&T Bell Labs where she contributed to the design of the DSP16 chip and developed new algorithms and architectures for image compression. Picard earned master’s and doctorate degrees in electrical engineering and computer science from MIT, and joined the MIT faculty in 1991. At MIT, she pioneered research on content-based retrieval of image and video, contributing to the Photobook system and introducing the use of new mathematical models and semantic descriptions such as Wold features. In 1997, she authored the book Affective Computing, laying the foundation for a new field of research giving computers skills of emotional intelligence. Picard led the world’s first research group focused on creating technology to recognize, interpret, and respond empathetically to emotion in multiple modalities, including physiology, face, posture, and task behavior. Applications of her research include autism, health, fitness, education, usability, marketing, and customer service.

THE SEVEN WONDERS OF COMPUTER ARITHMETIC

Earl Swartzlander, Professor of Electrical and Computer Engineering, University of Texas at Austin

Abstract: There are many seminal concepts in computer arithmetic that collectively enable the achievement of incredibly high levels of performance in current computers. In this seminar, seven key concepts are identified. They include the twos complement number system, carry lookahead adders, Booth multipliers, Wallace multipliers, Newton-Raphson and Goldschmidt iterative dividers, and the IEEE Standard for floating-point arithmetic.

Although some of these ideas are relatively new (for example, carry lookahead adders, Booth multipliers, Wallace multipliers, and Goldschmidt dividers date from the 1950s) while others (the twos complement number system and the Newton-Raphson dividers can be traced back to hundreds of years ago). Finally, the IEEE Standard is a political accomplishment as much as a technical wonder.

TOWARDS A SYSTEM THEORETIC FOUNDATION FOR CONTROL OVER NETWORKS

P. R. Kumar, Franklin W. Woeltge Professor of Electrical and Computer Engineering, University of Illinois at Urbana-Champaign

Abstract: We address several issues that are important for developing a comprehensive understanding of the problems of control over networks. Proceeding from bottom to top, we describe theoretical frameworks to study the following issues, and present some answers:

  • Network information theory: Are there limits to information transfer over wireless networks? How should nodes in a network cooperate to achieve information transfer?
  • In-network information processing: How should data from distributed sensors be fused over a wireless network? Can one classify functions of sensor data vis-à-vis how difficult they are to compute over a wireless network?
  • Real-time scheduling over wireless networks: How should packets with hard deadlines be scheduled for transmission over unreliable nodes? What QoS guarantees can be provided with respect to latencies and throughputs?
  • Clock synchronization over wireless networks: What are the ultimate limits to synchronization error? How should clocks be synchronized?
  • System-level guarantees in networked control: How can one provide overall guarantees on of networked control systems that take into account hybrid behavior, real-time interactions, and distributed aspects?
  • Abstractions and architecture: What are appropriate abstractions, and what is an appropriate architecture, to simplify networked control system design and deployment?

BETTER ARCHITECTURE AND NEW SECURITY APPLICATIONS FOR COARSE NETWORK MONITORING

Michael Reiter, Lawrence M. Slifkin Distinguished Professor, Department of Computer Science, University of North Carolina at Chapel Hill

Abstract: Busy networks today cannot afford to log all traffic traversing them, and consequently many network-monitoring applications make due with coarse traffic summaries. In this talk, we will describe an approach we have developed to improve the fidelity of these traffic summaries, by coordinating the monitoring performed by the network’s routers so as to achieve network-wide monitoring goals while respecting each router’s processing constraints. We also will describe our use of traffic summaries to detect a variety of stealthy network abuses (e.g., file-sharing traffic masquerading on other application ports, “hit-list” scans and malware propagation, data exfiltration by spyware, and botnet command-and-control) and even to identify the origin of epidemic malware spreads.
