and the paper [R_LDA_PRL.pdf] (An extension to the above TNN paper)

pp. 181-191, 2005.
[Usages:]
1. To find the KDDA based feature representation with RBF kernel,
1.1. use function [DFLD_Trans]=F_JDLDAPro() to find the regularized LDA subspace.
1.2. given a sample, x, its projection (y) to the above subspace can be obtained
by y=DFLD_Trans*x.
[Note:]
The regularization parameter $eta$ in the function F_JDLDAPro() has an influence on
the classification performance. Try different values of $eta$ to find the best one.
[Restrictions:]
In all documents and papers that report on research that uses the matlab codes, the
researcher(s) must reference the following two papers:
