+% this script trains similarity measures using RBM and SVM as in Table 3
+% please note that the RBM training is a probabilistic process.
+% Here, training is done on 20 random initialisations of RBM features ,
+% the test results corresponding to the RBM with the best training result are then
+% returned.
