The global convergence of the Polak-Ribière-Polyak conjugate gradient algorithm under inexact line search for nonconvex functions

open access: yesJournal of Computational and Applied Mathematics, 2019
Powell (1984) and Dai (2003) constructed respectively a counterexample to show that the Polak–Ribiere–Polyak (PRP) conjugate gradient algorithm fails to globally converge for nonconvex functions even when the exact line search technique is used, which ...

A new, globally convergent Riemannian conjugate gradient method [PDF]

open access: yes, 2013
This article deals with the conjugate gradient method on a Riemannian manifold with interest in global convergence analysis. The existing conjugate gradient algorithms on a manifold endowed with a vector transport need the assumption that the vector ...

Accelerating federated learning via momentum gradient descent [PDF]

open access: yes, 2019
Federated learning (FL) provides a communication-efficient approach to solve machine learning problems concerning distributed data, without sending raw data to a central server. However, existing works on FL only utilize first-order gradient descent (GD)

Global increase and geographic convergence in antibiotic consumption between 2000 and 2015

open access: yesProceedings of the National Academy of Sciences of the United States of America, 2018
Significance Antibiotic resistance, driven by antibiotic consumption, is a growing global health threat. Our report on antibiotic use in 76 countries over 16 years provides an up-to-date comprehensive assessment of global trends in antibiotic consumption.

On convergence of the maximum block improvement method [PDF]

open access: yes, 2015
. The MBI (maximum block improvement) method is a greedy approach to solving optimization problems where the decision variables can be grouped into a finite number of blocks. Assuming that optimizing over one block of variables while fixing all others is

An all-encompassing global convergence result for processive multisite phosphorylation systems. [PDF]

open access: yesMathematical Biosciences, 2016
Phosphorylation, the enzyme-mediated addition of a phosphate group to a molecule, is a ubiquitous chemical mechanism in biology. Multisite phosphorylation, the addition of phosphate groups to multiple sites of a single molecule, may be distributive or ...
