Simplicial Neural Networks

3 code implementations NeurIPS Workshop TDA_and_Beyond 2020 Stefania Ebli, Michaël Defferrard, Gard Spreemann

We present simplicial neural networks (SNNs), a generalization of graph neural networks to data that live on a class of topological spaces called simplicial complexes.

A Notion of Harmonic Clustering in Simplicial Complexes

no code implementations16 Oct 2019 Stefania Ebli, Gard Spreemann

We outline a novel clustering scheme for simplicial complexes that produces clusters of simplices in a way that is sensitive to the homology of the complex.

Clustering Topological Data Analysis

Using persistent homology to reveal hidden information in neural data

no code implementations22 Oct 2015 Gard Spreemann, Benjamin Dunn, Magnus Bakke Botnan, Nils A. Baas

We propose a method, based on persistent homology, to uncover topological properties of a priori unknown covariates of neuron activity.
