  Abstract: Convolutional networks have marked their place over the last few years as the#N#best performing model for various visual tasks. They are, however, most suited#N#for supervised learning from large amounts of labeled data. Previous attempts#N#have been made to use unlabeled data to improve model performance by applying#N#unsupervised techniques. These attempts require different architectures and training methods.#N#In this work we present a novel approach for unsupervised training#N#of Convolutional networks that is based on contrasting between spatial regions#N#within images.  This criterion can be employed within conventional neural net-#N#works and trained using standard techniques such as SGD and back-propagation,#N#thus complementing supervised methods.
