This paper develops a supervised dimensionality reduction method, Lorentzian Discriminant Projection (LDP), for discriminant analysis and classification Our method represents the structures of sample data by a manifold, which is furnished with a Lorentzian metric tensor Different from classic discriminant analysis techniques, LDP uses distances from points to their within-class neighbors and global geometric centroid to model a new manifold to detect the intrinsic local and global geometric structures of data set In this way, both the geometry of a group of classes and global data structures can be learnt from the Lorentzian metric tensor Thus discriminant analysis in the original sample space reduces to metric learning on a Lorentzian manifold The experimental results on benchmark databases demonstrate the effectiveness of our proposed method.
