WebDec 18, 2024 · Spectral graph convolutional networks are generalizations of standard convolutional networks for graph-structured data using the Laplacian operator. A common misconception is the instability of spectral filters, i.e. the impossibility to transfer spectral filters between graphs of variable size and topology. WebJan 1, 2024 · Spectral signatures have been used with great success in computer vision to characterise the local and global topology of 3D meshes. In this paper, we propose to use two widely used spectral signatures, the Heat Kernel Signature and the Wave Kernel Signature, to create node embeddings able to capture local and global structural … Webening based on concepts from spectral graph theory. We propose and justify new dis-tance functions that characterize the di er-ences between original and coarse graphs. We show that the proposed spectral distance nat-urally captures the structural di erences in the graph coarsening process.
