Carnegie Mellon joins NSF research consortium to develop tools for analyzing autism, other behaviors
Researchers in the School of Computer Science at Carnegie Mellon University will join a five-year, $10 million initiative funded by the National Science Foundation (NSF) to create novel tools for evaluating social interactions and other behaviors that can be used in diagnosing or treating behavioral disorders such as autism.
The Computational Behavioral Science Project, part of the Expeditions in Computing Program of the NSF's Directorate for Computer and Information Science and Engineering (CISE), includes collaborators from the University of Illinois at Urbana-Champaign (UIUC), the University of Southern California and the Massachusetts Institute of Technology, with the Georgia Institute of Technology serving as the lead institution.
"Using technologies such as computer vision and machine learning programs, we will develop new methods for gathering clues about a child's behavior that could lead to a diagnosis of autism at an early age, when therapy is most effective," said Anind Dey, associate professor in Carnegie Mellon's Human-Computer Interaction Institute. "Some of this information can be collected in clinics, but we hope some can be gleaned from as-yet untapped sources, such as the home videos that parents make all the time."
Takeo Kanade, the U.A. and Helen Whitaker University Professor of Robotics and Computer Science, will lead an effort at Carnegie Mellon using computer vision to automatically analyze videos, amateur or otherwise, for early signs of autistic behavior, such as the rocking, clapping and other repetitive stereotypical behaviors known collectively as stimming. Eye gaze, facial expressions and body posture are additional visual aspects of social engagement that could be analyzed.
"We aim at developing a new suite of technologies for imaging and understanding human behaviors, or behavior imaging," Kanade said. "Just as medical imaging revolutionalized medicine and science for the body and its actions, behavior imaging will revolutionalize medicine and science for the mind and its activities."
Other collaborators in the project will develop methods for analyzing speech and will develop wearable sensors and toys-as-sensors that can further enhance data gathering.
Meanwhile, Dey will work with colleagues in human-computer interaction at Georgia Tech and UIUC to develop methods for making sense of the data being generated by these new tools. "Educators, family members and clinicians all have different needs and interests and will want to have this data interpreted in a way that makes sense to them," Dey said.
Outreach activities will include ongoing collaborations with the Center for Excellence in Autism Research at the University of Pittsburgh, as well as major autism research centers in Atlanta, Boston, Urbana-Champaign, Ill., and Los Angeles.
Autism, which affects one out of every 110 children in the United States, represents a particularly compelling need for new methods of gathering behavioral data. But the long-term goal of the NSF-sponsored project is to develop a new discipline of computational behavioral science, which will draw equally from computer science and psychology to transform the study of human behavior.
The technologies being developed for the project will make it possible to automatically measure behavior over a long period of time for large numbers of individuals in a wide range of settings. Many disciplines, such as education, advertising and customer relations, could benefit from a more objective data-driven approach to behavioral assessment.
"There is a great deal of creativity in the computer science research community," said Deborah Crawford, acting assistant director for CISE at the NSF. "Our intentions with the Expeditions in Computing Program is to stimulate and use that creativity to expand the possibilities of computing," she said. "The researchers and collaborators we're supporting with these awards will also be exploring new computational approaches to some of the most vexing problems we face in science and the broader world."
The Expeditions in Computing Program include some of the largest single investments made by the directorate and the NSF in basic computer science research. Carnegie Mellon is the lead institution in an Expedition grant issued last year on Computational Modeling and Analysis of Complex Systems, made possible with stimulus money from the American Recovery and Reinvestment Act (ARRA).
