About the speed of Liblinear SVM 'train'

[cpsxhao]

Hi, thanks for your excellent codes. I got good performance when I use a set of 10000 pictures, with 5 landmarks. However, when I increase the landmarks to 9, the training of SVM is too slow -- after 'learn global regressors...', it can hardly go on. So would you like to give me some advice on it?

And can you tell me the meaning of the options of function 'train', especially 'heartscale'?

param = sprintf('-s 12 -p 0 -c %f -q heart_scale', 1/(size(binaryfeatures, 1)));
