Nonlinear Methods for Model Reduction
, 2020 The usual approach to model reduction for parametric partial differential equations (PDEs) is to construct a linear space $V_n$ which approximates well the solution manifold $\mathcal{M}$ consisting of all solutions $u(y)$ with $y$ the vector of ...

General Runge–Kutta–Nyström Methods for Linear Inhomogeneous Second-Order Initial Value Problems
MathematicsIn this paper, general Runge–Kutta–Nyström (GRKN) methods are developed and analyzed, tailored for second-order initial value problems of the form y″=Ly′+My+g(t), where L,M∈Rn×n are constant matrices with n≥1. The construction of embedded pairs of orders

Classification of structural MRI images in Alzheimer's disease from the perspective of ill-posed problems. [PDF]
PLoS ONE, 2012 BACKGROUND:Machine learning neuroimaging researchers have often relied on regularization techniques when classifying MRI images. Although these were originally introduced to deal with "ill-posed" problems it is rare to find studies that evaluate the ill ...
