Dealing with Lack of Training Data for Convolutional
Thanks to their capability to learn generalizable descriptors directly from images deep Convolutional Neural Networks (CNNs) seem the ideal solution to most pattern recognition problems. On the other hand to learn the image representation CNNs need huge sets of annotated samples that are unfeasible in many every-day scenarios. This is the case for example of Computer-Aided Diagnosis (CAD
