ISBN: 9781680839289
Category : Technology & Engineering
Languages : en
Pages : 262
Book Description
This monograph covers recent advances in a range of acceleration techniques frequently used in convex optimization. Using quadratic optimization problems, the authors introduce two key families of methods, namely momentum and nested optimization schemes. These methods are covered in detail and include Chebyshev Acceleration, Nonlinear Acceleration, Nesterov Acceleration, Proximal Acceleration and Catalysts and Restart Schemes.This book provides the reader with an in-depth description of the developments in Acceleration Methods since the early 2000s, whilst referring the reader back to underpinning earlier work for further understanding. This topic is important in the modern-day application of convex optimization techniques in many applicable areas.This book is an introduction to the topic that enables the reader to quickly understand the important principles and apply the techniques to their own research.

The Sales Acceleration Formula
Author: Mark Roberge
Publisher: John Wiley & Sons
ISBN: 1119047072
Category : Business & Economics
Languages : en
Pages : 227
Book Description
Use data, technology, and inbound selling to build a remarkable team and accelerate sales The Sales Acceleration Formula provides a scalable, predictable approach to growing revenue and building a winning sales team. Everyone wants to build the next $100 million business and author Mark Roberge has actually done it using a unique methodology that he shares with his readers. As an MIT alum with an engineering background, Roberge challenged the conventional methods of scaling sales utilizing the metrics-driven, process-oriented lens through which he was trained to see the world. In this book, he reveals his formulas for success. Readers will learn how to apply data, technology, and inbound selling to every aspect of accelerating sales, including hiring, training, managing, and generating demand. As SVP of Worldwide Sales and Services for software company HubSpot, Mark led hundreds of his employees to the acquisition and retention of the company's first 10,000 customers across more than 60 countries. This book outlines his approach and provides an action plan for others to replicate his success, including the following key elements: Hire the same successful salesperson every time — The Sales Hiring Formula Train every salesperson in the same manner — The Sales Training Formula Hold salespeople accountable to the same sales process — The Sales Management Formula Provide salespeople with the same quality and quantity of leads every month — The Demand Generation Formula Leverage technology to enable better buying for customers and faster selling for salespeople Business owners, sales executives, and investors are all looking to turn their brilliant ideas into the next $100 million revenue business. Often, the biggest challenge they face is the task of scaling sales. They crave a blueprint for success, but fail to find it because sales has traditionally been referred to as an art form, rather than a science. You can't major in sales in college. Many people question whether sales can even be taught. Executives and entrepreneurs are often left feeling helpless and hopeless. The Sales Acceleration Formula completely alters this paradigm. In today's digital world, in which every action is logged and masses of data sit at our fingertips, building a sales team no longer needs to be an art form. There is a process. Sales can be predictable. A formula does exist.

Eigenvalue analysis and convergence acceleration techniques for summation-by-parts approximations
Author: Andrea Alessandro Ruggiu
Publisher: Linköping University Electronic Press
ISBN: 9176850234
Category :
Languages : en
Pages : 57
Book Description
Many physical phenomena can be described mathematically by means of partial differential equations. These mathematical formulations are said to be well-posed if a unique solution, bounded by the given data, exists. The boundedness of the solution can be established through the so-called energy-method, which leads to an estimate of the solution by means of integration-by-parts. Numerical approximations mimicking integration-by-parts discretely are said to fulfill the Summation-By-Parts (SBP) property. These formulations naturally yield bounded approximate solutions if the boundary conditions are weakly imposed through Simultaneous-Approximation-Terms (SAT). Discrete problems with bounded solutions are said to be energy-stable. Energy-stable and high-order accurate SBP-SAT discretizations for well-posed linear problems were first introduced for centered finite-difference methods. These mathematical formulations, based on boundary conforming grids, allow for an exact mimicking of integration-by-parts. However, other discretizations techniques that do not include one or both boundary nodes, such as pseudo-spectral collocation methods, only fulfill a generalized SBP (GSBP) property but still lead to energy-stable solutions. This thesis consists of two main topics. The first part, which is mostly devoted to theoretical investigations, treats discretizations based on SBP and GSBP operators. A numerical approximation of a conservation law is said to be conservative if the approximate solution mimics the physical conservation property. It is shown that conservative and energy-stable spatial discretizations of variable coefficient problems require an exact numerical mimicking of integration-by-parts. We also discuss the invertibility of the algebraic problems arising from (G)SBP-SAT discretizations in time of energy-stable spatial approximations. We prove that pseudo-spectral collocation methods for the time derivative lead to invertible fully-discrete problems. The same result is proved for second-, fourth- and sixth-order accurate finite-difference based time integration methods. Once the invertibility of (G)SBP-SAT discrete formulations is established, we are interested in efficient algorithms for the unique solution of such problems. To this end, the second part of the thesis has a stronger experimental flavour and deals with convergence acceleration techniques for SBP-SAT approximations. First, we consider a modified Dual Time-Stepping (DTS) technique which makes use of two derivatives in pseudo-time. The new DTS formulation, compared to the classical one, accelerates the convergence to steady-state and reduces the stiffness of the problem. Next, we investigate multi-grid methods. For parabolic problems, highly oscillating error modes are optimally damped by iterative methods, while smooth residuals are transferred to coarser grids. In this case, we show that the Galerkin condition in combination with the SBP-preserving interpolation operators leads to fast convergence. For hyperbolic problems, low frequency error modes are rapidly expelled by grid coarsening, since coarser grids have milder stability restrictions on time steps. For such problems, Total Variation Dimishing Multi-Grid (TVD-MG) allows for faster wave propagation of first order upwind discretizations. In this thesis, we extend low order TVD-MG schemes to high-order SBP-SAT upwind discretizations.
