Quasi-Newton and Krylov Methods for the Solution of Nonconvex Trust-Region Subproblems
Johann Bourhis, Oihan Cordelier, Jean-Pierre Dussault +2
We study the solution of symmetric positive-definite linear systems by way of families of full- and limited-memory methods. Our contributions are threefold. We first derive new rel…
A rewriting of the relation between the acolinearity of annihilation photons and their energy in the context of positron emission tomography
Maxime Toussaint, Francis Loignon-Houle, Étienne Auger +2
Acolinearity of the annihilation photons observed in Positron Emission Tomography (PET) is described as following a Gaussian distribution. However, it is never explicitly said if i…
Scalable adaptive cubic regularization methods
Jean-Pierre Dussault, Dominique Orban
Adaptive cubic regularization (ARC) methods for unconstrained optimization compute steps from linear systems involving a shifted Hessian in the spirit of the Levenberg-Marquardt an…
Systematic Ensemble Learning for Regression
Roberto Aldave, Jean-Pierre Dussault
The motivation of this work is to improve the performance of standard stacking approaches or ensembles, which are composed of simple, heterogeneous base models, through the integra…
