Welcome to Topological Data Analysis seminar!
Location: LIT 368
Time: 11:45am – 12:35pm (5th period)
The purpose of this seminar is to discuss and learn different TDA topics and present papers on the subject in a non-formal setting. The seminar is run in the following format: a presenter gives a 20 min talk on a topic and the rest of the time we spend on a discussion.
In Spring 2023, our main topics of interest are various dimensionality reduction techniques, and distances in TDA and their stability properties.
