Discrete Ricci curvature formulations offer novel perspectives for characterizing geometric properties of weighted graphs. This work proposes continuous piecewise linear Ricci curvature flows and ...

This repository provides a python implementation of our piecewise linear regression algorithm both with CPU and GPU. The experiments that are shown in our paper are run with MATLAB which is a slower ...

In this work, we propose a graph approach for stability of piecewise linear systems. A stability criterion is presented based on the attractivity of an invariant region. The approach is applied to ...

In this paper, a new methodology for curve approximation is presented. The method is suitable for both self-intersected and non self-intersected curves, it combines elements from graph theory and from ...
