Performance for NMF and PCA data compression in classification and data reconstruction.

<p>(a) The relationship between SVM classification accuracy and the width of patches extracted from the NMF spatial intensity maps. The gray dotted line shows the patch width of 20 × 20 pixels used to generate the results presented in this paper. (b) The relationship between reconstruction err...
