Data Science Seminars

The IMA Data Science Seminars are a forum for data scientists of IMA academic and industrial partners to discuss and learn about recent developments in the broad area of data science. Some of the talks will be by group members of the IMA Data Science Lab discussing recent developments in the area and possibly presenting their own work, while other talks will be by local and visiting data scientists with a few talks by external speakers.

The seminars are organized by Jeff Calder, Will Leeb, and Gilad Lerman of the School of Mathematics at the University of Minnesota, and will generally take place Tuesdays from 1:25-2:25 p.m. in Walter Library 402 for or by Zoom. Please check the individual seminar page for details
