Supervised Kernel Principal Component Analysis by Most Expressive Feature Reordering

• Krzysztof Slot, Krzysztof Adamiak, Piotr Duch, Dominik Zurek
• 2015

The presented paper is concerned with feature space derivation through feature selection. The selection is performed on results of kernel Principal Component Analysis (kPCA) of input data samples.… (More)
