Using the following kernel by default:
kernel = kern.rbf(Q, ARD=Q>1) + kern.bias(Q, np.exp(-2)) + kern.white(Q, np.exp(-2))

Added the functionality of showing a mosaic of NxN reconstructed images
when the size of the number of elements in the feature vector greater
than dimensions[0]*dimensions[1].

brendan_faces(): normalizing the feature vectors w.r.t. the
global mean and standard deviation.
Changed optimisation constraints because it was never converging.

a88eadbb35 image_show() is now able to use a palette to map quantized images to their original color. This uses PIL (import Image). I also enabled the image to be normalised from 0 to 255 in a more robust way (before this, it was assuming images ranged from 0 to 1). 2013-05-14 17:35:16 +01:00
