[0081] Data Recognition Effects on Artificial Datasets
[0082] First we construct four artificial datasets, where the data points are distributed on four independent subspaces {Si,i=1:4}, {Ci,i=1:4} are the basis vectors of four of these spaces, where Ci+1=RCi, 1
[0083]LRR and SSC are classic subspace segmentation algorithms; LS3C is an SSC algorithm for constructing hidden spaces with PCA regularization;
[0084] NLS3C uses kernel PCA regularization to construct the SSC of the latent space; LSRC is a robust LRR algorithm; latLRR is the LRR of the kernel PCA regularization to construct the latent space; LRSC is the local constrained LRR algorithm of the PCA regularization to construct the hidden space; proposed algorithm.
