Graph Curvature for Differentiating Cancer Networks

WebFor a given graph, the Ricci flow gives a “Ricci flow metric” on each edge as edge weights, such that under these edge weights, the Ricci curvature of the graph is mostly equal everywhere. In [Ni3], this “Ricci flow metric” is shown to be able to detect communities. Both Ricci curvature and Ricci flow metric can act as a graph ... WebIn this paper, we present a novel self-supervised Riemannian graph neural network (SelfℛGNN). Specifically, we design a curvature-varying Riemannian GNN with a theoretically grounded time encoding, and formulate a functional curvature over time to model the evolvement shifting among the positive, zero and negative curvature spaces.
