Whether it is clustering, classification, or regression, at a very basic level, many problems in data science can be reduced to understanding properties of collections of points living in a high-dimensional space. It's little wonder then that geometry has played an important (if sometimes understated) role in the field. Whether it is helping interpret and improve today's state-of-the-art models or driving progress toward the algorithms of tomorrow, geometry is a powerful lens with which to understand the principal algorithms and methods of data science. In this special session we will hear from some of the top researchers at the intersection of mathematics and data science, each of whom is using ideas or techniques from geometry (and topology) to push the field of data science forward.
