Web- "Sign and Basis Invariant Networks for Spectral Graph Representation Learning" Figure 2: Pipeline for using node positional encodings. After processing by our SignNet, the learned positional encodings from the Laplacian eigenvectors are added as additional node features of an input graph ([X,SignNet(V )] denotes concatenation). WebBefore considering the general setting, we design neural networks that take a single eigenvector or eigenspace as input and are sign or basis invariant. These single space architectures will become building blocks for the general architectures. For one subspace, a sign invariant function is merely an even function, and is easily parameterized.
WebApr 22, 2024 · Our networks are universal, i.e., they can approximate any continuous function of eigenvectors with the proper invariances. They are also theoretically strong for graph representation learning -- they can approximate any spectral graph convolution, can compute spectral invariants that go beyond message passing neural networks, and can …
