Toeplitz Least Squares Problems, Fast Algorithms and Big Data

no code implementations24 Dec 2021 Ali Eshragh, Oliver Di Pietro, Michael A. Saunders

In time series analysis, when fitting an autoregressive model, one must solve a Toeplitz ordinary least squares problem numerous times to find an appropriate model, which can severely affect computational times with large data sets.

A Julia implementation of Algorithm NCL for constrained optimization

no code implementations6 Jan 2021 Ding Ma, Dominique Orban, Michael A. Saunders

We give numerical results from a Julia implementation of Algorithm NCL on tax policy models that do not satisfy the LICQ, and on nonlinear least-squares problems and general problems from the CUTEst test set.

Estimating Cellular Goals from High-Dimensional Biological Data

1 code implementation11 Jul 2018 Laurence Yang, Michael A. Saunders, Jean-Christophe Lachance, Bernhard O. Palsson, José Bento

The latter approach is important because often the known/observed biochemical reactions are not enough to explain observations, and hence there is a need to extend automatically the model complexity by learning new chemical reactions.

Proximal Newton-type methods for minimizing composite functions

1 code implementation7 Jun 2012 Jason D. Lee, Yuekai Sun, Michael A. Saunders

We generalize Newton-type methods for minimizing smooth functions to handle a sum of two convex functions: a smooth function and a nonsmooth function with a simple proximal mapping.
