Title: NLTGCR: A class of Nonlinear Acceleration Procedures based on Conjugate Residuals

Title: NLTGCR:基于共轭残差的非线性加速算法类

Authors:Huan He, Ziyuan Tang, Shifan Zhao, Yousef Saad, Yuanzhe Xi
Abstract: This paper develops a new class of nonlinear acceleration algorithms based on extending conjugate residual-type procedures from linear to nonlinear equations. The main algorithm has strong similarities with Anderson acceleration as well as with inexact Newton methods - depending on which variant is implemented. We prove theoretically and verify experimentally, on a variety of problems from simulation experiments to deep learning applications, that our method is a powerful accelerated iterative algorithm.
Abstract: 本文开发了一类新的非线性加速算法,该算法通过将共轭残差型过程从线性方程扩展到非线性方程。 主要算法与安德森加速方法以及不精确牛顿方法有很强的相似性——这取决于所实现的变体。 我们理论上证明并实验验证了,在从仿真实验到深度学习应用的各种问题上,我们的方法是一种强大的加速迭代算法。
