Signal recovery by proximal forward-backward splitting
收藏 引用
MULTISCALE MODELING & SIMULATION 2005年 第4期4卷 1168-1200页
作者: Combettes, PL Wajs, VR Univ Paris 06 Lab Jacques Louis Lions F-75005 Paris France
We show that various inverse problems in signal recovery can be formulated as the generic problem of minimizing the sum of two convex functions with certain regularity properties. This formulation makes it possible to... 详细信息

On Inexact Relative-Error Hybrid Proximal Extragradient, forward-backward and Tseng's Modified forward-backward Methods with Inertial Effects
收藏 引用
SET-VALUED AND VARIATIONAL ANALYSIS 2020年 第2期28卷 301-325页
作者: Alves, M. Marques Marcavillaca, Raul T. Univ Fed Santa Catarina Dept Matemat BR-88040900 Florianopolis SC Brazil
For solving monotone inclusion problems, we propose an inertial under-relaxed version of the relative-error hybrid proximal extragradient method. We study the asymptotic convergence of the method, as well as its nonas... 详细信息

Maximum Principle for Optimal Control Problems of forward-backward Regime-Switching Systems Involving Impulse Controls
收藏 引用
MATHEMATICAL PROBLEMS IN ENGINEERING 2015年 第1期2015卷 1-13页
作者: Wang, Shujun Wu, Zhen Shandong Univ Sch Math Jinan 250100 Shandong Peoples R China
This paper is concerned with optimal control problems of forward-backward Markovian regime-switching systems involving impulse controls. Here the Markov chains are continuous-time and finite-state. We derive the stoch... 详细信息

A forward-backward SPLITTING METHOD FOR MONOTONE INCLUSIONS WITHOUT COCOERCIVITY
收藏 引用
SIAM JOURNAL ON OPTIMIZATION 2020年 第2期30卷 1451-1472页
作者: Malitsky, Yura Tam, Matthew K. Univ Gottingen Inst Numer & Appl Math D-37083 Gottingen Germany Univ Melbourne Sch Math & Stat Parkville Vic 3010 Australia
In this work, we propose a simple modification of the forward-backward splitting method for finding a zero in the sum of two monotone operators. Our method converges under the same assumptions as Tseng's forward-b... 详细信息

Classical Solutions of Path-Dependent PDEs and Functional forward-backward Stochastic Systems
收藏 引用
MATHEMATICAL PROBLEMS IN ENGINEERING 2013年 第1期2013卷 1-11页
作者: Ji, Shaolin Yang, Shuzhen Shandong Univ Inst Financial Studies Jinan 250100 Shandong Peoples R China Shandong Univ Inst Math Jinan 250100 Shandong Peoples R China Shandong Univ Sch Math Jinan 250100 Shandong Peoples R China
In this paper we study the relationship between functional forward-backward stochastic systems and path-dependent PDEs. In the framework of functional Ito calculus, we introduce a path-dependent PDE and prove that its... 详细信息

SIAM JOURNAL ON IMAGING SCIENCES 2013年 第3期6卷 1199-1226页
作者: Raguet, Hugo Fadili, Jalal Peyre, Gabriel Univ Paris 09 CNRS CEREMADE F-75775 Paris 16 France Univ Caen 6 CNRS ENSICAEN GREYC F-14050 Caen France
This paper introduces a generalized forward-backward splitting algorithm for finding a zero of a sum of maximal monotone operators B + Sigma(n)(i=1) A(i), where B is cocoercive. It involves the computation of B in an ... 详细信息

Strong convergence of the forward-backward splitting method with multiple parameters in Hilbert spaces

OPTIMIZATION 2018年 第4期67卷 493-505页
作者: Wang, Yamin Wang, Fenghui Henan Normal Univ Sch Math & Informat Sci Xinxiang Peoples R China Henan Normal Univ Sch Math & Informat Sci Henan Engn Lab Big Data Stat Anal & Optimal Contr Xinxiang Peoples R China Luoyang Normal Univ Dept Math Luoyang Peoples R China
Many problems arising from machine learning, signal & image recovery, and compressed sensing can be casted into a monotone inclusion problem for finding a zero of the sum of two monotone operators. The forward-bac... 详细信息

A generalized forward-backward splitting method for solving quasi inclusion problems in Banach spaces
收藏 引用
NUMERICAL algorithmS 2016年 第4期71卷 915-932页
作者: Cholamjiak, Prasit Univ Phayao Sch Sci Phayao 56000 Thailand
We propose a new general type of splitting methods for accretive operators in Banach spaces. We then give the sufficient conditions to guarantee the strong convergence. In the last section, we apply our results to the... 详细信息

A central aim of population genetics is the inference of the evolutionary history of a population. To this end, the underlying process can be represented by a model of the evolution of allele frequencies parametrized ... 详细信息

forward-backward and Tseng's Type Penalty Schemes for Monotone Inclusion Problems
收藏 引用
SET-VALUED AND VARIATIONAL ANALYSIS 2014年 第2期22卷 313-331页
作者: Bot, Radu Ioan Csetnek, Ernoe Robert Univ Vienna Fac Math A-1090 Vienna Austria
We deal with monotone inclusion problems of the form 0 a A x + D x + N (C) (x) in real Hilbert spaces, where A is a maximally monotone operator, D a cocoercive operator and C the nonempty set of zeros of another cocoe... 详细信息
