Clustering for directed graphs using parametrized random walk diffusion kernels

no code implementations1 Oct 2022 Harry Sevi, Matthieu Jonckheere, Argyris Kalogeratos

In this paper, we introduce a new clustering framework, the Parametrized Random Walk Diffusion Kernel Clustering (P-RWDKC), which is suitable for handling both directed and undirected graphs.

Generalized Spectral Clustering for Directed and Undirected Graphs

no code implementations7 Mar 2022 Harry Sevi, Matthieu Jonckheere, Argyris Kalogeratos

In this paper, we present a generalized spectral clustering framework that can address both directed and undirected graphs.

Harmonic analysis on directed graphs and applications: from Fourier analysis to wavelets

no code implementations28 Nov 2018 Harry Sevi, Gabriel Rilling, Pierre Borgnat

We introduce a novel harmonic analysis for functions defined on the vertices of a strongly connected directed graph of which the random walk operator is the cornerstone.

The Asymptotic Performance of Linear Echo State Neural Networks

no code implementations25 Mar 2016 Romain Couillet, Gilles Wainrib, Harry Sevi, Hafiz Tiomoko Ali

In this article, a study of the mean-square error (MSE) performance of linear echo-state neural networks is performed, both for training and testing tasks.
