WebIf fis basis invariant and v. 1,...,v. k. are a basis for the firstkeigenspaces, then z. i = z. j. The problem z. i = z. j. arises from the sign/basis invariances. We instead propose using sign equiv-ariant networks to learn node representations z. i = f(V) i,: ∈R. k. These representations z. i. main-tain positional information for each node ...

WebFeb 1, 2024 · Abstract: We introduce SignNet and BasisNet---new neural architectures that are invariant to two key symmetries displayed by eigenvectors: (i) sign flips, since if v is … 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. delight beds and furniture
