Summer Seminar Series: Nonlinear Dimensionality Reduction - Myths, Dogmas and Problems

2025/07/10 (Thu.) 11:00~12:00
  • Date : 2025/07/10 (Thu.) 11:00~12:00
  • Location : Auditorium, 6 Floor, Institute of Mathematics (NTU Campus)
  • Speaker : Stefan Steinerberger (University of Washington)
  • Website : https://www.math.sinica.edu.tw/applied-math
  • Abstract : 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.
