Jan 24, 2021 · As you could guess from the name, GCN is a neural network architecture that works with graph data. The main goal of GCN is to distill graph and node attribute information into the vector node representation aka embeddings. Below you can see the intuitive depiction of GCN from Kipf and Welling (2016) paper.
For example, for a node-level semi-supervised classification task, the cross-entropy loss can be used for the labeled nodes in the training set. 2.4. Build ...
Dec 01, 2021 · The first model is a neural network that aims at classifying each node using only its own features, and then discarding all information encoded within the graph representation. This model serves as a baseline in order to measure the information brought by the structural information for node classification.
Jan 05, 2021 · Abstract. Image classification is an important, real-world problem that arises in many contexts. To date, convolutional neural networks (CNNs) are the state-of-the-art deep learning method for image classification since these models are naturally suited to problems where the coordinates of the underlying data representation have a grid structure.

01.12.2021 · Using such a model, the main question is the definition of the convolution kernels C (s).A natural method, named Vanilla ConvGNN, uses only one kernel defined by C = A + I where A denotes the adjacency matrix of the graph and I the identity matrix. used two convolution kernels defined by C (1) = A and C (2) = I to split the weights applied to own node features and the …
Nov 22, 2021 · Understanding the black-box representations in Deep Neural Networks (DNN) is an essential problem in deep learning. In this work, we propose Graph-Based Similarity (GBS) to measure the similarity of layer features. Contrary to previous works that compute the similarity directly on the feature maps, GBS measures the correlation based on the ...

There has been other work in using neural methods to learn graph representations. The representations obtained by these ap-proaches are tailored for a supervised task and are not determined solely based on the graph structure. Niepert et al. [34] developed a framework (PSCN) to learn graph representations using convolu-tional neural networks ...
