The engineering community has greatlybenefited from these recent advances to the point where convex optimization has nowemerged as a major signal-processing technique on the other hand, innovative applica-tions of convex optimization in signal processing combined with the need for robust andefficient methods that can operate in real time have motivated the optimization commu-nity to develop additional needed results and methods. The combined efforts in both theoptimization and signal-processing communities have led to technical breakthroughs ina wide variety of topics due to the use of convex optimization This includes solutions tonumerous problems previously considered intractable; recognizing and solving convex-optimization problems that arise in applications of interest; utilizing the theory of convexoptimization to characterize and gain insight into the optimal-solution structure and toderive performance bounds; formulating convex relaxations of difficult problems; anddeveloping general purpose or application-driven specific algorithms, including thosethat enable large-scale optimization by exploiting the problem structureThis book aims at providing the reader with a series of tutorials on a wide varietyof convex-optimization applications in signal processing and communications, writtenby worldwide leading experts, and contributing to the diffusion of these new developments within the signal-processing community. The goal is to introduce convexoptimization to a broad signal-processing community, provide insights into how convexoptimization can be used in a variety of different contexts, and showcase some notablesuccesses. The topics included are automatic code generation for real-time solvers, graphical models for autoregressive processes, gradient-based algorithms for signal-recoveryapplications, semidefinite programming(SDP)relaxation with worst-case approximationperformance, radar waveform design via SDP, blind non-negative source separation forimage processing, modern sampling theory, robust broadband beamforming techniquesdistributed multiagent optimization for networked systems, cognitive radio systems viagame theory, and the variational-inequality approach for Nash-equilibrium solutionsPrefaceThere are excellent textbooks that introduce nonlinear and convex optimization, providing the reader with all the basics on convex analysis, reformulation of optimizationproblems, algorithms, and a number of insightful engineering applications. This book istargeted at advanced graduate students, or advanced researchers that are already familiarwith the basics of convex optimization. It can be used as a textbook for an advanced graduate course emphasizing applications, or as a complement to an introductory textbookthat provides up-to-date applications in engineering. It can also be used for self-study tobecome acquainted with the state of-the-art in a wide variety of engineering topicsThis book contains 12 diverse chapters written by recognized leading experts worldwide, covering a large variety of topics. Due to the diverse nature of the book chaptersit is not possible to organize the book into thematic areas and each chapter should betreated independently of the others. a brief account of each chapter is given nextIn Chapter 1, Mattingley and Boyd elaborate on the concept of convex optimizationin real-time embedded systems and automatic code generation. As opposed to genericsolvers that work for general classes of problems, in real-time embedded optimization thesame optimization problem is solved many times, with different data, often with a hardreal-time deadline. Within this setup the authors propose an automatic code-generationsystem that can then be compiled to yield an extremely efficient custom solver for theproblem familyIn Chapter 2, Beck and Teboulle provide a unified view of gradient-based algorithmsfor possibly nonconvex and non-differentiable problems, with applications to signalrecovery. They start by rederiving the gradient method from several different perspectives and suggest a modification that overcomes the slow convergence of the algorithmThey then apply the developed framework to different image-processing problems suchas e1-based regularization, TV-based denoising, and Tv-based deblurring, as well ascommunication applications like source localizationIn Chapter 3, Songsiri, Dahl, and Vandenberghe consider graphical models for autore-gressive processes. They take a parametric approach for maximum-likelihood andmaximum-entropy estimation of autoregressive models with conditional independenceconstraints, which translates into a sparsity pattern on the inverse of the spectral-densitymatrix. These constraints turn out to be nonconvex. To treat them the authors proposea relaxation which in some cases is an exact reformulation of the original problem. Theproposed methodology allows the selection of graphical models by fitting autoregressiveprocesses to different topologies and is illustrated in different applicationsThe following three chapters deal with optimization problems closely related to SDPand relaxation techniquesIn Chapter 4, Luo and Chang consider the SDP relaxation for several classes ofquadratic-optimization problems such as separable quadratically constrained quadraticprograms(QCQPs)and fractional QCQPs, with applications in communications and signal processing. They identify cases for which the relaxation is tight as well as classes ofquadratic-optimization problems whose relaxation provides a guaranteed, finite worstcase approximation performance. Numerical simulations are carried out to assess theefficacy of the SDP-relaxation approach

Quast-M,cisc译者注:本文均是 Google翻译结果,仅对代码和板式作调整,欢迎修改分享软件背景与简介欢迎来到数据分析ROOT!测量与理论模型的比较是实验物理学中的标准仟务之一。在最简单的情况下,“模型”只是提供测量数据预测的函数。通常,模垩取决于参数。这种模型可以简单地表示“电流I与电压U成比例”,并且实验者的任务包括从一组测量中确定电阻R作为第一步,需要数据的可视化。接下来,通常必须应用一些操作,例如,校正或参数转换。通常,这些操作是复杂的,并且应该提供强大的数学函数和程序库-例如,考虑应用于输入光谱的积分或峰值搜索或傅立叶变换以获得模型描述的实际测量偵。实验物理学的一个特点是影响每个测量的不可避免的不确定性,可视化工具必须包括这些。在随后的分析中,必须正确处理错误的统计性质作为最后一步,将测量值与模型进行比较,并且需要在此过程中确定自由模型参数。有关适合数据点的函数(模型)的示例,请参见图1.1。有儿种标准方法可供使用,数据分析工具应能方便地访问其中一种以上。还必须提供量化测量和模型之间一致性水平的方法。通常,要分析的数据量很大-考虑借助计算机累积的细粒度测量。因此,可用工具必须包含易于使用且有效的方法来存储和处理数据在量子力学中,模型通常仅根据许多参数预测测量的概率密度函数(“pdf),并且实验分析的目的是从观察到的频率分布中提取参数,其中观察测量。这种测量需要生成和可视化频率分布的装置,所谓的直方图和严格的统计处理,以从纯粹的统计分布中提取模型参数。预期数据的模拟是数据分析的另一个重要方面。通过重复生成“伪数据”,其以与用于真实数据的预期相同的方式进行分析,可以验证或比较分析过程。在许多情况卜,测量误差的分布并不是精确已知的,并且模拟提供了测试不同假设的景响的可能性。满足上述所有要求的强大软件框架是ROOT,这是个由日内瓦欧洲核了研究中心欧洲核研究组织协调的开源项目ROOT非常灵活,既可以在自己的应用程序中使用编程接口,也可以提供用于交互式数据分析的图腦用户界面。木文档的目的是作为初学者指南,并根据学生实验室中解决的典型问题为您自己的用例提供可扩展的示例。本指南有望为您未来科学工作中更复杂的应用奠定基础,建立在现代,最先进的数据分析上具之上本指南以教程的形式向您介绍ROOT包。根据“边做边学”的原则,这个目标将通过具体的例子来完成。也正因为这个原因,本指南无法涵盖ROOT包的所有复杂性。然而,一日您对以卜章节中介绍的概念有信心,您将能够欣赏ROOT用户指南( The Root Users guide2015)并浏览类参考(根参考指南2013)以査找所有详细信息您可能会感兴。您甚至可以查看代码本身,因为ROOT是一个免费的开源广品。与本教程并行使用这些文档!ROOT数据分析框架本身是编写的,并且在很大程度上依赖于C++编程语言:需要些关于C++的知识。如果您不了解这种语言的含义,Js可以利用有关C++的大量文献。ROOT可用于许多平台( Linux, Mac osx, Windows….),但在本指南中我们将隐含地假设您使用的是 Linux。你需要做的第一件事就是安装ROOT,不是吗?获取最新的ROOT版本非常简单。只需在此网页htp:/ root, cern.ch/ downloading-root上寻找“专业版”。您将找到针对不同体系结构的预编译版木,或者您自凵编译的ROOT源代码。只需拿起您需要的味道并按照安装说明操作即可。让我们深入了解ROOT!ROOT基础既然你凵经安装了ROOT,那么你止在运行的这个交互式 shell是什么?就像这样:ROOT带来了双重功能。它有一个宏的解释器(Cing( What is Cling”2015)),您可以从命令行运行或像应用程序一样运行。但它也是一个可以评估任意语句和表达式的交互式 shell这对于调试,快速黑客攻击和测试非常有用。我们先来看一些非常简单的例子2.1ROOT作为计算器您甚至可以使用ROOT交互式she代替计算器!使用该命令启动ROOT交互式shelroot在你的Liux机器上。提示应该很快出现:root「8让我们来看看这里显示的步骤root [0] 1+1(int)2root[1]2*(4+2)/12(doub1e)1.0000root [2] sqrt(3.( double)1.732051root[3]1>2(bool) falseroot [4] TMath: Pi()( double)3.141593root [5] TMath: Erf( 2)( double).222703不错。您可以看到,ROOT不仅可以输入C++语句,还可以输入存在于 MAth命名空间中的高级数学函数。现在让我们做一些更详尽的事情。一个众所周知的几何系列的数字小例root [6 double X=5(double)0.500000root [7] int N=30(int)30root [8] double geom series=0(doub1e)8.099root [9] for (int i=0; i
