Contributed discussion to Bayesian solution uncertainty quantification for differential equations by Oksana A. Chkrebtii, David A.Campbell, Ben Calderhead, and Mark A.Girolami

Abstract

We begin by introducing the main ideas of the paper, and we give a

brief description of the method proposed. Next, we discuss an alternative approach

based on B-spline expansion, and lastly we make some comments on the method’s

convergence rate.
