Topology, Homology, and Applications to Data

Please join us for a presentation by Inga Johnson (Dept. of Mathematics) this Friday, April 5th at 3:00 pm in the Library Hatfield Room. The title of her talk is: Topology, Homology, and Applications to Data

Abstract: Topology is the subfield of mathematics that is concerned with the study of shape. Mathematicians have studied topological questions for the past 250 years. However, in just the past 15 years topology has been found to have many different applications to real world problems. One of these is to use a topological tool called persistence homology to understand and analyze high dimensional and complex data sets.

This talk will be an introduction to topology and the concept of homology. We will then use homology to a look at examples of how topological ideas can be used to give new and surprising insight towards understanding data. This talk will emphasize examples and concepts. Prerequisites will be minimal.

As always, light refreshments will be provided.
