2016-06-28 17:35:39 -0600 | marked best answer | PCA + SVM ? Hi, I am trying to reduce the dimensionality of my feature set using PCA and then classification using SVM. I have created and populated my feature matrix and label matrix : Where each row corresponds to an image and each column is a feature. The features are histogram bins (256) from multiple regions in the image (90 regions). 90x256 = 23040. I now want to reduce the 23040 features to something less before training, say 512 features. I have this: My question is, is this correct ? And how would I now use prediction with PCA ? Thanks ! |
