Graph neural networks (GNNs) have been widely used in deep learning on graphs. They can learn effective node representations that achieve superior performances in graph analysis tasks such as node classification and node clustering. However, most methods ignore the...
Higher order learning with graphs Recently there has been considerable interest in learning with higher order relations (i.e., three-way or higher) in the unsupervised and semi-supervised settings. Hypergraphs and tensors have been proposed as the natural way of represen... S Agarwal,K Branson...

order connections, e.g. through face-to-face meetings, but the pattern of calls can reveal the existence of such connections. Network Science offers many approaches to discovering these local group interactions from a network. It is natural to work with small sub-graphs, motifs6,17, or if ...
These approaches modify and improve a given classifier with the aim of matching it with the imbalanced data. In [3,15], a formulation of an approach adopting ensemble techniques is proposed to improve the classifier performance in handling high-dimensional data. (c) Ensemble learning techniques Th...
