Learning Directly From Data Rather Than Human-Provided Expertise

11-19-18

Alumnus Yong Sheng Soh (PhD ’18, ACM), advised by Professor Venkat Chandrasekaran, has won the 2018 INFORMS Optimization Society Student Prize for his paper entitled Learning Semidefinite-Representable Regularizers. Regularization-based algorithms are widely used in the solution of data-driven inverse problems arising in statistics, operations research, signal processing, and machine learning. These approaches typically require a great deal of prior domain-specific expertise about the structure of the underlying problem. Such expertise is especially challenging to obtain in the modern era of 'Big Data' in which our ability to sense all manner of phenomena and produce massive datasets far exceeds our ability to understand the underlying mechanisms governing the phenomena. In his award-winning work, which has been accepted for publication at the Journal of the Foundations of Computational Mathematics, Yong Sheng has developed a new framework for learning suitable regularization methods directly from data rather from human-provided expertise.

Two International Aerospace Leaders Receive von Kármán Wings Award

11-19-18

This year's International von Kármán Wings Award honorees were Jean-Yves Le Gall, president of the French Centre National d'Études Spatiales and A. S. Kiran Kumar, Vikram Sarabhai Professor and former chairman of the Indian Space Research Organization and former secretary of the Indian Department of Space. The ceremony also featured the presentation of two scholarships to honor top graduate students in aerospace. "This event is absolutely unique," said Professor Ares Rosakis and chairman of the the Aerospace Historical Society. "What makes it so is that it reflects the phenomenal international connections between Caltech, GALCIT, JPL, and NASA and it also highlights the true international nature of aerospace. More importantly, it gives us the opportunity to take a glimpse at the future by also honoring our own students who will one day define the future of space science and the future of space technology."

Partners In Innovation

Ten years ago, Caltech and City of Hope forged a partnership that combined what each institute was best at—engineering and medicine, respectively—with the goal of developing new biomedical technologies. At this year’s partnership celebration two projects were highlighted one involving Professor Yu-Chong Tai’s work on tracking tumors and the other building on Professor Morteza Gharib’s device to measure heart health.
