47 cluster labels were found to have a similarity of 0.5 to some ILSVRC12 class, leaving 134 cluster labels whose highest similarity to any ILSVRC12 class was less than 0.5.
more than two thirds of the highly pure pattern clusters learned by our network were dissimilar to all of the 1,000 ILSVRC12 classes used to pretrain the VGG network, indicating that our model is able to generalize far beyond the set of classes found in the ILSVRC12 data.
