Graph networks with spectral message passing
WebA method for object recognition from point cloud data acquires irregular point cloud data using a 3D data acquisition device, constructs a nearest neighbor graph from the point cloud data, constructs a cell complex from the nearest neighbor graph, and processes the cell complex by a cell complex neural network (CXN) to produce a point cloud … WebSpectral clustering transforms the data clustering problem into a graph-partitioning problem and classifies data points by finding the optimal sub-graphs. Traditional spectral clustering algorithms use Gaussian kernel function to construct the similarity matrix, so they are sensitive to the selection of scale parameter. In addition, they need to randomly …

WebDespite the higher expressive power, we show that K K -hop message passing still cannot distinguish some simple regular graphs and its expressive power is bounded by 3-WL. To further enhance its expressive power, we introduce a KP-GNN framework, which improves K K -hop message passing by leveraging the peripheral subgraph information in each hop. WebA new message passing formulation for graph convolutional neural networks is proposed. • An effective regularization technique to address over-fitting and over-smoothing. • The proposed regularization can be applied to different graph neural network models. • Semi-supervised and fully supervised learning settings are considered. •
