Lasso回归是目前处理多重共线性的主要方法之一，相对于其他方法，更容易产生稀疏解，在参数估计的同时实现变量选择，因而可以用来解决检验中的多重共线性问题，以提高检验的效率。

This is known as symmetric multiprocessing support.

这即是对称的多重处理支援。

In multiprocessing,a programming technique used to prevent access to critical data by both processing units at the same time.

Multiprocessing system is a computer system employing two or more interconnected processing units to execute programs.

多重处理系统是一种计算机系统，是用两个或多个相互连接的处理器，同时执行多个程序。

Answer: Symmetric multiprocessing treats all processors as equals, and I/O can be processed on any CPU.

对称的多重处理视所有的处理器为对手，而且输入／输出能在任何的中央处理器上被处理。

Almost by definition, multiprocessing systems are large, and yet major components, the secondary processors are really microcomputers

根据定义，几乎所有的多重处理系统都有是庞大的系统，它的主要部件即辅助处理器实际上都是微型计算机

Chapter 8: We discuss the acceleration of multigrid by Krylov subspace approaches, and recognize the reason for slow convergence of algebraic multigrid methods is that error reduction is significantly less efficient for some very specific error components which may cause a few eigenvalues of the algebraic multigrid iteration matrix to be considerably closer to 1 than all the rest. However, the eigenvectors belonging to the few isolated eigenvalues can be expected to be typically captured after only a few conjugate gradient iterations, which accelerate algebraic multigrid algorithms. Theoretical analysis and numerical results of some practical problems show the iterant recombination accelerates algebraic multigrid convergence.

第八章：先介绍用Krylov子空间迭代法加速一般多重网格方法收敛的基本框架，然后紧紧抓住引起代数多重网格方法收敛减慢的根本原因往往是误差减小对几个特别的误差分量不明显，这导致代数多重网格方法的迭代矩阵的几个特征值接近于1，而共轭梯度方法则能比较典型地捕捉属于孤立特征值的特征向量，从而推导出有效的共轭梯度加速算法和程序实现，不仅从一些具体的实际应用例子的数值结果去验证迭代复合加速收敛的效果，而且还从理论上分析了预处理共轭梯度法加速代数多重网格法收敛的机理。
