Networks are ubiquitous in the real world, such as social net-works [Fortunato, 2010], biological networks [Girvan and Newman, 2002] and traffic networks [Asif et al., 2016]. Network embedding (a.k.a. graph embedding) learns low-dimensional latent representations of nodes while preserving (a) Homophily (b) Heterophily (c) Hybrid (proposed)

10-701 Introduction to Machine Learning Midterm Exam

4 Deep Neural Networks - 10 points In homework 3, we counted the model parameters of a convolutional neural network (CNN), which gives us a sense how much memory a CNN will consume. Now we estimate the computation overhead of CNNs by counting the FLOPs (oating point operations). For simplicity we only consider the forward pass.

Graph Neural network vs. Network embedding In some sense, they are different Graphs exist in mathematics (Data Structure) Mathematical structures used to model pairwise relations between objects Networks exist in the real world (Data) Social networks, logistic networks, biology networks, transaction networks, etc.

Gradient Descent with Early Stopping is Provably Robust to

When learning from pairwise relations, noisy labels can be connected to graph clustering and community detection problems [1,14,54]. Label noise is also connected to outlier robustness in regression which is a traditionally well-studied topic. In the context of robust regression and high-dimensional statistics, much of

former part of the computation graph in TensorFlow (13). Sequence reweighting, calculation of one-site amino acid frequen-cies, entropies, and coevolutionary couplings and related scores take place on the GPU, and the extracted features are passed into the convolutional layers of the network (most previous approaches have precomputed these terms).

Graph convolutional networks (GCN) [17] provide a further simpli cation by a rst-order approximation of graph ltering and are applied to semi-supervised [17] and subsequently few-shot learning [8]. Kipf and Welling [17] apply the loss function to labeled examples to make predictions on unlabeled ones.

We propose Dimensional reweighting Graph Convolutional Networks (DrGCNs), in which the input of each layer of the GCN is reweighted by global node representation information. Our discovery is that the experimental performance of GCNs can be greatly improved under this simple reweighting scheme.

GRAPH CONVOLUTIONAL NETWORKS FOR LEARNING WITH FEW CLEAN AND

Graph neural networks are generalizations of convolutional networks to non-Euclidean spaces (Bronstein et al., 2017). Early spectral methods (Bruna et al., 2014; Henaff et al., 2015) have been succeeded by Chebyshev polynomial approximations (Defferrard et al., 2016), which avoid the high computational cost of computing eigenvectors.
