Regularized Locality Preserving Learning of Pre-Image Problem in Kernel Principal Component Analysis
15 years 4 months ago
In this paper, we address the pre-image problem in kernel principal component analysis (KPCA). The preimage problem finds a pattern as the pre-image of a feature vector defined in...
