Asprey Distinguished Lecture Series: DREiMac—Dimensionality Reduction with Eilenberg-MacLane Spaces

Prof. Jose Perea of Northeastern University presents a framework leveraging topological data structure to construct low-dimensional coordinates consistent with underlying data topology.

This talk presents a framework to leverage the topological structure of data, measured via persistent cohomology, and construct low-dimensional coordinates in classifying spaces consistent with the underlying data topology.

A first lecture, "What Is Topological Data Analysis?," takes place on April 23, 2026, at 5:00 p.m., also in Rockefeller Hall, Room 300.

The Asprey Distinguished Lecture Series in Mathematics is sponsored by the Department of Mathematics and Statistics. 

This event is free and open to the public.
