Globally maximizing, locally minimizing unsupervised discriminant projection with applications to face and palm biometrics

Globally maximizing, locally minimizing : unsupervised discriminant projection with applications to face and palm biometrics

This paper develops an unsupervised discriminant projection (UDP) technique for dimensionality reduction of high-dimensional data in small sample size cases. UDP can be seen as a linear approximation of a multimanifolds-based learning framework which takes into account both the local and nonlocal qu...
