The Spectral Theorem, Singular values, and Facial Recognition

浙江大学数学科学学院九十周年院庆系列活动之八十九

Title:  The Spectral Theorem, Singular values, and Facial Recognition

Speaker:  Professor John Hubbard (Cornell University)

Time: Oct 25 (Thur.)  10：45-11：45

Location: 4F lecture hall, Sir Run Run Shaw Business Administration building

Abstract:  As probably many of you know, Facebook is capable of putting names on faces in pictures that you send them. How do they do it?The information is proprietary, but one can listen to whispers from experts.  In this lecture I propose to describe at least part of what Facebook does: an algorithm known as Eigenfaces. The main point I want to make is that Eigenfaces is straightforward linear algebra, having to do with eigenvalues and eigenvectors, orthogonal projections, etc.
