Dilated Residual Networks - CVF Open Access
openaccess.thecvf.comConvolutional networks were originally developed for classifying hand-written digits [9]. More recently, convolu-tional network architectures have evolved to classify much more complex images [8, 13, 14, 6]. Yet a central aspect of network architecture has remained largely in place.

arxiv.orgGraph convolutional networks. In recent years, several convolutional neural network architectures for learning over graphs have been proposed (e.g., [4, 9, 8, 17, 24]). The majority of these methods do not scale to large graphs or are designed for whole-graph classification (or both) [4, 9, 8, 24].
