To run the experiment on the Oxford flower 17:

1. Download the Chi2 distances (distancematrices17gcfeat06.mat and distancematrices17itfeat08.mat) 
   from http://www.robots.ox.ac.uk/~vgg/data/flowers/17/index.html (see the item 4&5 on the web page), and copy the two mat files to folder \data\17_Similarity_Matrices\ . 
   The three data splits from the same web page have already been preprocessed and included in this code package (\data\datasplits).

2. Run \code\Data_Generation.m to generate and preprocess the data used in experiment.

3. Run \code\demo_RKR_CG(DK)_Flower17.m to get the recognition accuracies on the three data splits.
