CANCELLED - Andrea Bertozzi, UCLA, presents “Mathematics of Crime,” and “Geometric Graph-based Methods for High Dimensional Data.” (3/25 and 3/26)

We regret to inform you these lectures have been cancelled.

On March 25th at 5pm in Rockefeller Hall 300, Professor Bertozzi will discuss the fascinating story behind her participation on the UCLA team that developed a "predictive policing" computer program that zeros-in on areas that have the highest probability of crime, now used in over fifty cities worldwide, in her lecture “Mathematics of Crime” as part of the 2019 Asprey Distinguished Lecture Series in Mathematics. The diverse use of mathematics in studying residential burglaries, gang crimes, and other criminal activities will also be discussed as well as new problems in machine learning related to crime data analysis for prediction and classification. Reception at 4:30pm.

On March 26th at 3pm in Rockefeller Hall 300, Bertozzi will present “Geometric Graph-based Methods for High Dimensional Data,” new methods for segmentation of large datasets with graph-based structure. The methods make parallels between geometric ideas in Euclidean space such as motion by mean curvature, ported to a graphical framework, and can be made rigorous. We show diverse examples including image processing applications such as image and video labeling and hyperspectral video segmentation, and machine learning and community detection in social networks, including modularity optimization posed as a graph total variation minimization problem. Reception at 2:30pm.

Professor Andrea Bertozzi holds the Betsy Wood Knapp Chair for Innovation and Creativity at UCLA, where she is a Professor of Mathematics. She is the Director of Applied Mathematics, overseeing the graduate and undergraduate research training programs at UCLA. Her many honors include a Sloan Research Fellowship, an NSF Presidential Early Career Award, the Society of Industrial and Applied Mathematics Kovalevsky Prize, and a Simons Math + X Investigator Award. She is a Fellow of the Society of Industrial and Applied Mathematics, a Fellow of the American Mathematical Society, and a Fellow of the American Physical Society. Professor Bertozzi was elected a Fellow the American Academy of Arts and Sciences in 2010, and in 2018 was elected to the National Academy of Sciences.
