Data Science Seminars
The IMA Data Science Seminar hosts research talks that are broadly related to the areas of data science and machine learning, which may include theoretical work on mathematical foundations of data science, interactions between data science and other domains, as well as applications of data science in science and engineering. The goal of the seminar is to bring together faculty, postdocs, students, and industrial partners who are interested in data science and broadly related fields to exchange ideas and foster collaborations.
The seminars are organized by Jeff Calder, Jasmine Foo, Will Leeb, Gilad Lerman, Yulong Lu, and Li Wang of the School of Mathematics at the University of Minnesota, and will generally take place Tuesdays from 1:25-2:25 p.m. in Lind Hall 325 or via Zoom. Please check the individual seminar page for details.
