New Algorithm Helps Autonomous Vehicles Find Themselves, Summer or Winter

06-24-21

Without GPS, autonomous systems get lost easily. Now a new algorithm developed at Caltech allows autonomous systems to recognize where they are simply by looking at the terrain around them—and for the first time, the technology works regardless of seasonal changes to that terrain. The general process, known as visual terrain-relative navigation (VTRN), was first developed in the 1960s. By comparing nearby terrain to high-resolution satellite images, autonomous systems can locate themselves. The problem is that, in order for it to work, the current generation of VTRN requires that the terrain it is looking at closely matches the images in its database. To overcome this challenge, Anthony Fragoso, Lecturer in Aerospace; Staff Scientist, Connor Lee, Graduate student in Aerospace, Austin McCoy, Undergraduate, and Soon-Jo Chung, Bren Professor of Aerospace and Control and Dynamical Systems and research scientist at JPL, turned to deep learning and artificial intelligence (AI) to remove seasonal content that hinders current VTRN systems.

FUTURE Ignited

11-04-20

Nearly 200 undergraduates from more than 120 colleges and universities across the country joined Caltech for FUTURE Ignited, a virtual event that aimed to encourage students of color to pursue graduate studies in science and engineering. The goal of FUTURE Ignited is to diversify STEM with students of color who will go on to become incredible graduate students and scientific leaders in their respective fields. [Caltech story]

Machine Learning Helps Robot Swarms Coordinate

07-14-20

Soon-Jo Chung, Bren Professor of Aerospace, Yisong Yue, Professor of Computing and Mathematical Sciences, postdoctoral scholar Wolfgang Hönig, and graduate students Benjamin Rivière and Guanya Shi, have designed a new data-driven method to control the movement of multiple robots through cluttered, unmapped spaces, so they do not run into one another. "Our work shows some promising results to overcome the safety, robustness, and scalability issues of conventional black-box artificial intelligence (AI) approaches for swarm motion planning with GLAS and close-proximity control for multiple drones using Neural-Swarm," says Chung.

Ishani A. Karmarkar Receives 2020 Henry Ford II Scholar Award

06-22-20

Applied and computational mathematics student Ishani A. Karmarkar is a recipient of the 2020 Henry Ford II Scholar Award. Ishani is interested in data science and numerical algorithms, as well as applications to physical problems. This summer, she will be working on a SURF project on graph-based semi-supervised learning algorithms with Bamdad Hosseini, Senior Postdoctoral Scholar Research Associate, and Andrew Stuart, Bren Professor of Computing and Mathematical Sciences. In the past, she has also worked on a fluid modelling project with Sandra Troian, Professor of Applied Physics, Aeronautics, and Mechanical Engineering, and completed a summer internship at Facebook. The Henry Ford II Scholar Award is funded under an endowment provided by the Ford Motor Company Fund. The award is made annually to engineering students with the best academic record at the end of the third year of undergraduate study.

President Rosenbaum Highlights Postdocs as "Unsung Heroes"

09-24-18

In a letter to the Caltech community during National Postdoc Appreciation Week, the Caltech President emphasizes the role this key group plays at the Institute. He stated, “Caltech's mission of world-leading research and education depends crucially on our postdoctoral scholars. Although their time at Caltech may be short, they quickly become vital parts of the Institute's intellectual fabric.” [President’s Letter] [EAS Postdoc Resource Page]

Joel (J.N.) Franklin Passes Away

11-28-17

Joel (J.N.) Franklin, Professor of Applied Mathematics, Emeritus, passed away on November 18, 2017 at the age of 87. Professor Franklin joined Caltech in 1957 and worked closely with Gilbert McCann, professor of applied science, who was one of the early champions of computing at Caltech (and inventor of an analog computer in 1946). Professor Dan Meiron recalls, "Joel excelled as a scholar and researcher … if any of us in applied math—and the Institute in general—had any questions about matrix theory, linear programming, etc. we could consult with Joel and he always pointed us to the relevant results often connected to work he had done in the past."
