WebOct 6, 2024 · In addition, spectral graph convolution with cluster pooling provides a more faithful representation of changes in local geometry. This allows us to successfully segment connected parts of a 3D object, such as the strap from the body of the handbag, the wings from the tail fins of the airplane and the handle from the blade of the knife. WebJan 25, 2024 · Node cluster pooling considers graph pooling a problem of node clustering and maps similar nodes to a cluster by learning soft assignment matrices [17], [18], [19]. However, the high computational requirements of node clusters obstruct their expansion into large graphs. ... Spectral clustering with graph neural networks for graph pooling; …

WebTraditional graph clustering methods consist of two sequential steps, i.e., constructing an affinity matrix from the original data and then performing spectral clustering on the resulting affinity matrix. This two-step strategy achieves optimal solution for each step separately, but cannot guarantee that it will obtain the globally optimal clustering results.
