Nonlinear Dimensionality Reduction - Myths, Dogmas and Problems
Mathematics of Data & Decisions| Speaker: | Stefan Steinerberger, University of Washington |
| Location: | 1025 PDSB |
| Start time: | Tue, Apr 22 2025, 12:00PM |
The purpose of this talk is to give a gentle (and mathematical!) introduction into a family of dimensionality reduction algorithms that have become very popular (including t-SNE, UMAP and others). We'll survey some of the underlying ideas, what we know and what we don't know. There'll be a fair number of open problems, the theory is in its infancy.
