Gradient sliding for composite optimization [PDF]
Mathematical Programming, 2015 We consider in this paper a class of composite optimization problems whose objective function is given by the summation of a general smooth and nonsmooth component, together with a relatively simple nonsmooth term. We present a new class of first-order methods, namely the gradient sliding algorithms, which can skip the computation of the gradient for ...

Estimation and Optimization of Composite Outcomes
Journal of machine learning research : JMLR, 2017 There is tremendous interest in precision medicine as a means to improve patient outcomes by tailoring treatment to individual characteristics. An individualized treatment rule formalizes precision medicine as a map from patient information to a recommended treatment.

Modelling and Analysis Library Development for Helicopter Blade and Slender Wings [PDF]
INCAS Bulletin, 2020 In this study, we suggest a framework for optimal design of a composite wing structure with a high aspect ratio at the initial design stage. The optimization framework calculates allowances in the first ply failure, buckling failure and bearing-bypass ...

Accelerating Stochastic Composition Optimization
J. Mach. Learn. Res., 2016 Consider the stochastic composition optimization problem where the objective is a composition of two expected-value functions. We propose a new stochastic first-order method, namely the accelerated stochastic compositional proximal gradient (ASC-PG) method, which updates based on queries to the sampling oracle using two different timescales. The ASC-PG
