Yaser S. Abu-Mostafa

Professor of Electrical Engineering and Computer Science

The Learning Systems Group at Caltech studies the theory and applications of Machine Learning (ML). The theory of ML uses mathematical and statistical tools to estimate the information (data and hints) needed to learn a given task. The applications are very diverse and continue to expand to every corner of science and technology. The group works on medical applications of ML, on e-commerce and profiling applications, and on computational finance, among other domains. These applications use the latest techniques of neural networks and other models, and often give rise to novel ML theory and algorithms. Our latest projects are data-driven approach to predicting the spread of COVID-19 in every U.S. county, and ML approach to medical diagnostics using low-resolution ultrasound.

H. Jane Bae

Assistant Professor of Aerospace

Professor Bae's research focuses on the physical understanding and modeling of structures associated with near-wall turbulence. Her main research goal is to develop high-fidelity models that reduce the computational cost to simulate high-Reynolds-number turbulent flows. These models will allow simulations to be utilized in the design cycle of wind farms and aircrafts and in predictions of atmospheric flows, reducing the overall time and effort associated with these processes. She also studies the physical mechanisms that generate and sustain turbulence, which, in turn, fuels new modeling approaches. She has interests in applying data-driven methods, machine learning, and other novel methods to turbulence modeling.

Katherine L. (Katie) Bouman

Assistant Professor of Computing and Mathematical Sciences, Electrical Engineering and Astronomy; Rosenberg Scholar; Investigator, Heritage Medical Research Institute

Katie Bouman's research focuses on computational imaging: designing systems that tightly integrate algorithm and sensor design, making it possible to observe phenomena previously difficult or impossible to measure with traditional approaches. Imaging plays a critical role in advancing science. However, as science continues to push boundaries, traditional sensors are reaching the limits of what they can measure. Katie's group combines ideas from signal processing, computer vision, machine learning, and physics to find and exploit hidden signals for both scientific discovery and technological innovation. For example, in collaboration with the Event Horizon Telescope, Katie's group is helping to build a computational earth-sized telescope that is taking the first images of a black hole and is analyzing its images to learn about general relativity in the strong-field regime.
