It is based on an efficient variant of convolutional neural networks which operate directly on graphs. 🔸 The choice of convolutional architecture is motivated via a localized first-order approximation of spectral graph convolutions. 🔸 The model scales linearly in the number of graph edges and learns hidden layer representations that encode both local graph structure and features of nodes. #innovation #artificialintelligence #computervision
I'll keep this in mind
Ashish, I was just wanting to study such a thing this morning, and now you have provided it! Thanks buddy!
Thank you
Edge updates = it is a perpendicular where all components are meeting to origin.
🔸 The term ‘convolution’ in Graph Convolutional Networks is similar to Convolutional Neural Networks in terms of weight sharing. The main difference lies in the data structure, where GCNs are the generalized version of CNN that can work on data with underlying non-regular structures. 🔸 The insertion of Adjacency Matrix (A) in the forward pass equation of GCNs enable the model to learn the features of neighboring nodes. This mechanism can be seen as a message passing operation along the nodes within the graph. 🔸 Renormalization trick is used to normalize the features in Fast Approximate Spectral-based Graph Convolutional Networks by Thomas Kipf and Max Welling (2017). 🔸 GCNs can learn features representation even before training
