Event Description:

The Department of Mathematics and Statistics of Swarthmore College invites all to The Dresden Memorial Lectures. Bernd Sturmfels (MPI Leipzig and UC Berkeley): “Geometry of Tensors”

November 28th, 2017 Lecture 1: “Applications of Tensors and their Eigenvectors" Eigenvectors of square matrices are central to linear algebra. Eigenvectors of tensors are a natural generalization, with many emerging applications. This lecture offers a first introduction, with numerous pictures.

November 29th, 2017 Lecture 2: “Gaussian Mixtures and their Tensors in Data Science" Mixtures of Gaussians are ubiquitous in data science. We discuss the geometry of these statistical models, with focus on tensors of moments. The rank of symmetric tensors arises when all covariance matrices are zero. We present work with Amendola and Ranestad that characterizes Gaussian mixtures that are identifiable from their moments.
