Description
The topological structure of data is widely relevant in various applications, hence raising the question of the stability of topological features. In this talk we address the stability of 1-dimensional holes in a simplicial complex through the optimisation of a functional that combines the spectra of the classical graph Laplacian with the one of the higher-order Hodge Laplacian. The proposed procedure is based on a matrix ODE formulation and a constrained gradient flow approach; the method’s performance is illustrated on synthetic quasi-triangulation datasets and transportation networks.
