WebIt is unknown whether all extended graph manifolds or all higher graph manifolds have residually nite fundamental group, see Section 12.1 in [FLS15]. We show that there are many examples which do have residually nite fundamental group, both in the extended graph mani-fold setting and in the pure complex-hyperbolic higher graph manifold setting. WebJul 1, 2024 · In this paper, we propose a Graph Convolutional Network with Manifold Regularization (GCNMR). Our proposed model exploits data-driven graphs in two ways. First, it integrates feature propagation over graphs. Second, it ensures that estimated labels satisfy the manifold regularization.
