Convexity or concavity of these examples can be shown by verifying the basic inequality of convex functions as: (i). Convexity: a function f is convex if and only if for 0≤θ≤1 : (0.1)f(θ(x)+(1−θ)y)≤θf(x)+(1−θ)f(y),∀x,y∈domf.(...
Anoutput functionis a function that an optimization function calls at each iteration of its algorithm. Typically, you use an output function to generate graphical output, record the history of the data the algorithm generates, or halt the algorithm based on the data at the current iteration. You...

where u_i:\mathbb R\to\mathbb R is the utility function associated with the i-th receiver. (You can think of u_i\left( R_i \right) as the revenue obtained for providing a bit rate R_i to receiver i , so the objective is to maximize the total revenue.) You can assume that the...
简介:【深度学习系列】(二)--An overview of gradient descent optimization algorithms 一、摘要 梯度下降优化算法虽然越来越流行,但经常被用作黑盒优化器,因为很难找到对其优缺点的实际解释。本文旨在为读者提供有关不同算法行为的直观信息,使他们能够使用这些算法。在本概述过程中,我们将介绍梯度下降的不同变体,总结...

Schwefel’s function is defined as:XML Copy f(x,y) = (-x * sin(sqrt(abs(x))) + (-y * sin(sqrt(abs(y))) The function has a minimum value of -837.9658 when x = y = 420.9687. In Figure 1 this minimum value is at the far-left corner of the graph. The function is delibe...
,I only determines the domain of p which can be considered as an implicit constraint in the domain of the objective function. For constraint ∑i=1Ipi=Pmax , one way is to consider this constraint in the objective function without any approximation. In this line, we have: p_I=P_{\max...
