Topological Data Visualization Workshop

May 16 - 20, 2022     University of Iowa

Organizers: Isabel Darcy, University of Iowa and Bei Wang, University of Utah

Funded by NSF DMS RTG 2038103: PI Keiko Kawamuro

The workshop format is expected to be in person; however, many talks will be available online. Thus we expect to have both in person and online participants. Not all activities will be available to online participants.

Some datasets are too small for standard statistical/data analysis to accurately characterize the data. Others are extremely large and data size reduction methods may be needed. One solution is to use topological data analysis to simplify and/or visualize data. This workshop will include both tutorials and research talks on topological techniques for visualizing data.

    Schedule

    We will have tutorials on Monday, Tuesday, and Wednesday. Tutorial days start with coffee at 8:30am and talks at 9am. Most tutorial days end at 5:30pm.

    We will have research talks on Thursday and Friday with coffee at 8:30am and talks starting at 9am. We will end at 5pm on Thursday and 3:00pm on Friday.

    Lunch will be on your own. There are many restaurants within walking distance.

    * means an in person presentation. Presenters without a * will be giving their talk via zoom.
