Training a Machine to Watch Soccer

08-25-17

Yisong Yue, Assistant Professor of Computing and Mathematical Sciences, and colleagues have developed an algorithm that can automatically recognize formations of teams—how they arrange themselves on the field—when analyzing player tracking data. The algorithm can also imitate players' behavior. "We're training the algorithm to understand soccer at the same level that a fan would. It's not just mindlessly watching faceless players move across a field; it's watching strikers and right midfielders and forwards arrange themselves in specific formations," says Professor Yue.

Deep Learning Networks and Sensorimotor Control

08-08-17

Professor John Doyle and colleagues are among only nineteen groups in the United States to receive National Science Foundation (NSF) funding to conduct innovative research focused on neural and cognitive systems. They aim is to integrate the capabilities of deep learning networks into a biologically inspired architecture for sensorimotor control that can be used to design more robust platforms for complex engineered systems.

Creature-Cataloging Contest for Computers

08-02-17

Caltech and Cornell teamed up to create the iNaturalist Challenge, a competition to create the best machine-learning algorithm for identifying the world's plant and animal species. The contest was an outgrowth of the institutions' previous work together on Visipedia, a visual encyclopedia created by a network of people and machine-learning computers that harvest image information off the internet. The technology was developed for the encyclopedia by Pietro Perona's Vision Group at Caltech and Serge Belongie's Computer Vision Group at Cornell Tech. [Caltech story]

Designing Computer Software of the Future

07-25-17

Fernando Brandao, Bren Professor of Theoretical Physics, and colleagues are developing quantum algorithms for optimization problems. "We are still far from knowing all the applications of quantum computing, and that's part of the excitement—there are possibilities we haven't even dreamed of yet,” says Professor Brandao.

Neural Networks Model Audience Reactions to Movies

07-21-17

Yisong Yue, Assistant Professor of Computing and Mathematical Sciences, and colleagues have created a new deep-learning software capable of assessing complex audience reactions to movies using the viewer's facial expressions. "Understanding human behavior is fundamental to developing AI [artificial intelligence] systems that exhibit greater behavioral and social intelligence. For example, developing AI systems to assist in monitoring and caring for the elderly relies on being able to pick up cues from their body language. After all, people don't always explicitly say that they are unhappy or have some problem," Professor Yue says. [Caltech story]

Meet Caltech alumnus and Technologist Behind Airbnb “Joebot”

06-30-17

Joe Zadeh is vice president of product for Airbnb. At Caltech, he pursued graduate work in bioengineering, designing biomolecules and created algorithms for self-assembling nucleic-acid structures. Addressing other alumni he states, “Caltech gave you a degree in a field, but it also taught you how to think. What you’re doing is trying to [take] something nebulous and make it concrete. In some ways, that’s what start-ups do. Actually a lot of start-ups don’t look a lot different structurally from most research labs at Caltech.” [Techer story]

Chou Doctoral Prize in IST Established

06-10-17

The Ben P.C. Chou Doctoral Prize recognizes outstanding doctoral dissertations in the broad area of information science and technology. The Prize was established by his wife, June, and his son, Scott (BS 1986), as a lasting tribute for Ben's lifetime dedication to the pursuit of scholarly research and foregoing personal gain in favor of always doing the right thing for society. Professor Pen-chu “Ben” Chou was born in China and suffered a childhood disrupted by a revolutionary war that ultimately took his father. At the age of 13, his mother took him and his two younger sisters to Taiwan as war refugees where she raised the three of them on her own. Prof Chou went on to complete his undergraduate at Tunghai University, his master’s degree at the University of Missouri, and his doctorate at the University of Oklahoma. He spent the bulk of his career doing research and teaching at The Texas Center for Superconductivity at the University of Houston and Jilin University in Changchun, China. Prof Chou is noted for his pioneering contributions in developing photoreactivity for thin film superconductors and helping establish OCEF, an international charitable foundation headquartered in Houston, Texas. The first winner of this prize was Albert Chern whose advisor was Peter Schröder. [Read Dr. Chern’s thesis]
