Cuomo’s executive order by maintaining a six-foot distance from others in public and washing hands frequently for at least 20 seconds.
2019 Asprey Lectures in Mathematics with Andrea Bertozzi, UCLA "Geometric Graph-based Methods for High Dimensional Data" Abstract: We present 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.
