Positivity-preserving schemes for some nonlinear stochastic PDEs
Charles-Edouard Bréhier, David Cohen, Johan Ulander
We introduce a positivity-preserving numerical scheme for a class of nonlinear stochastic heat equations driven by a purely time-dependent Brownian motion. The construction is insp…
Analysis of a positivity-preserving splitting scheme for some nonlinear stochastic heat equations
Charles-Edouard Bréhier, David Cohen, Johan Ulander
We construct a positivity-preserving Lie--Trotter splitting scheme with finite difference discretization in space for approximating the solutions to a class of nonlinear stochastic…
Splitting schemes for FitzHugh--Nagumo stochastic partial differential equations
Charles-Edouard Bréhier, David Cohen, Giuseppe Giordano
We design and study splitting integrators for the temporal discretization of the stochastic FitzHugh--Nagumo system. This system is a model for signal propagation in nerve cells wh…
ManiFeSt: Manifold-based Feature Selection for Small Data Sets
David Cohen, Tal Shnitzer, Yuval Kluger +1
In this paper, we present a new method for few-sample supervised feature selection (FS). Our method first learns the manifold of the feature space of each class using kernels captu…
