Deep neural network models have established themselves as an unparalleled force in the domains of vision, speech and text processing applications in recent years. However, graphs have formed a significant component of data analytics including applications in Internet of Things, social networks, pharmaceuticals and bioinformatics. An important characteristic of these deep learning techniques is their ability to learn the important features which are necessary to excel at a given task, unlike traditional machine learning algorithms which are dependent on handcrafted features. However, there have been comparatively fewer e�orts in deep learning to directly work on graph inputs. Various real-world problems can be easily solved by posing them as a graph analysis problem. Considering the direct impact of the success of graph analysis on business outcomes, importance of studying these complex graph data has increased exponentially over the years. In this thesis, we address three contributions towards understanding graph data: (i) The first contribution seeks to find anomalies in graphs using graphical models; (ii) The second contribution uses deep learning with spatio-temporal random walks to learn representations of graph trajectories (paths) and shows great promise on standard graph datasets; and (iii) The third contribution seeks to propose a novel deep neural network that implicitly models attention to allow for interpretation of graph classification. v
