Random walks on simplicial complexes

no code implementations12 Apr 2024 Thomas Bonis, Laurent Decreusefond, Viet Chi Tran, Zhihan Iris Zhang

Whereas the Laplacian of a graph has a simple probabilistic interpretation as the generator of a continuous time Markov chain on the graph, things are not so direct when considering simplicial complexes.

Complex systems in Ecology: a guided tour with large Lotka-Volterra models and random matrices

no code implementations12 Dec 2022 Imane Akjouj, Matthieu Barbier, Maxime Clenet, Walid Hachem, Mylène Maïda, François Massol, Jamal Najim, Viet Chi Tran

Ecosystems represent archetypal complex dynamical systems, often modelled by coupled differential equations of the form $$ \frac{d x_i}{d t} = x_i \varphi_i(x_1,\cdots, x_N)\ , $$ where $N$ represents the number of species and $x_i$, the abundance of species $i$.

Estimation of dense stochastic block models visited by random walks

no code implementations14 Jun 2020 Viet Chi Tran, Thi Phuong Thuy Vo

We are interested in recovering information on a stochastic block model from the subgraph discovered by an exploring random walk.
