Graph theoretical approaches have been proven to be effective in the characterization of connected systems, as well quantifying their dysfunction due perturbation. In this paper, we show advantage a non-Euclidean (hyperbolic) representation networks identify local connectivity perturbations and characterize induced effects on large scale. We propose two perturbation scores based representations latent geometric space, obtained through an embedding onto hyperbolic Poincar\'e disk. numerically demonstrate that these methods are able localize with homogeneous or heterogeneous degree connectivity. apply framework most perturbed brain areas epileptic patients following surgery. This study is conceived effort developing more powerful tools represent analyze networks, it first network techniques case epilepsy.

Abstract Multimodal graph learning techniques have demonstrated significant potential in modeling brain networks for Alzheimer’s disease (AD) detection. However, most existing methods rely on Euclidean space representations and overlook the scale-free small-world properties of networks, which are characterized by power-law distributions dense local clustering nodes. This oversight results distortions when representing these complex structures. To address this issue, we propose a novel multimodal Poincaré Fréchet mean convolutional network (MochaGCN) AD MochaGCN leverages exponential growth characteristics hyperbolic to capture networks. Specifically, combine convolution extract features from enhancing their rep-resentations space. Our approach constructs integrating information diffusion tensor imaging (DTI) functional magnetic resonance (fMRI) data. Experiments Disease Neuroimaging Initiative (ADNI) dataset demonstrate that proposed method outperforms state-of-the-art techniques.
