Linear Programming for Optimization

Linear Programming for Optimization Mark A. Schulze, Ph.D. Perceptive Scientific Instruments, Inc. 1. Introduction
1 .1 Definition Linear programming is the name of a branch of applied mathematics that deals with solving optimization problems of a particular form. Linear programming problems consist of a linear cost function (consisting of a certain number of variables) which is to be minimized or maximized subject to a certain number of constraints. The constraints are linear inequalities of the variables used in the cost function. The cost function is also sometimes called the objective function. Linear programming is closely related to linear algebra; the most noticeable difference is that linear programming often uses inequalities in the problem statement rather than equalities. 1 .2 History Linear programming is a relatively young mathematical discipline, dating from the invention of the simplex method by G. B. Dantzig in 1947. Historically, development in linear programming is driven by its applications in economics and management. Dantzig initially developed the simplex method to solve U.S. Air Force planning problems, and planning and scheduling problems still dominate the applications of linear programming. One reason that linear programming is a relatively new field is that only the smallest linear programming problems can be solved without a computer. 1 .3 Example (Adapted from [1].) Linear programming problems arise naturally in production planning. Suppose a particular Ford plant can build Escorts at the rate of one per minute, Explorer at the rate of one every 2 minutes, and Lincoln Navigators at the rate of one every 3 minutes. The vehicles get 25, 15, and 10 miles per gallon, respectively, and Congress mandates that the average fuel economy of vehicles produced be at least 18 miles per gallon. Ford loses $1000 on each Escort, but makes a profit of $5000 on each Explorer and $15,000 on each Navigator. What is the maximum profit this Ford plant can make in one 8-hour day?

模式识别--第二讲线性分类器

第 1 页第二讲线性分类器一、判别函数1、决策论方法在模式识别中，如果根据模式特征信息，按照决策论的思路，以一定的数量规则来采取不同的分类决策，将待识别的模式划分到不同的类别中去，就称为模式识别的决策论方法。

在决策论方法中，特征空间被划分成不同的区域，每个区域对应一个模式类，称为决策区域（Decision Region ）。

当我们判定待识别的模式位于某个决策区域时，就判决它可以划归到对应的类别中。

图1 决策区域需要注意的是：决策区域包含模式类中样本的分布区域，但不等于模式类的真实分布范围。

2、判别函数如果特征空间中的决策区域边界（Decision Boundary ）可以用一组方程0)( x i G来表示，则将一个模式对应的特征向量x 代入边界方程中的)(x i G ，确定其正负符号，就可以确定该模式位于决策区域边界的哪一边，从而可以判别其应当属于的类别，)(x i G 称为判别函数（Discriminant Function ）。

判别函数的形式可以是线性的（Linear ）或非线性（Non-linear）的。

第 2 页例如图2就显示了一个非线性判别函数，当G (x )>0时，可判别模式x ∈ω1；当G (x )<0时，可判别x ∈ω2。

图2 非线性判别函数非线性判别函数的处理比较复杂，如果决策区域边界可以用线性方程来表达，则决策区域可以用超平面（Hyperplane ）来划分，无论在分类器的学习还是分类决策时都比较方便。

例如图3中的特征空间可以用两个线性判别函数来进行分类决策：当G 21(x )>0且G 13(x )>0时，x ∈ω2；当G 13(x )<0且G 21(x )<0时，x ∈ω3；当G 21(x )<0 且 G 13(x )>0时，x ∈ω1；当G 21(x )>0且G 13(x )<0时，x 所属类别无法判别。

Introduction and main resultsIn this paper, we shall assume that the reader is familiar with the fundamental results and the stardard notations of the Nevanlinna's value distribution theory of meromorphic functions [12, 14,16]. In addition, we will use the notation )(f σ，)(f μand )(f λto denote respectively the order of growth, the lower order of growth and the exponent of convergence of the zeros of a meromorphic function f ，)(f e σ（[see 8]），the e-type order of f(z), is defined to berf r T f r e ),(log lim )(+∞→=σ Similarly, )(f e λ，the e-type exponent of convergence of the zeros of meromorphic function f , is defined to berf r N f r e )/1,(log lim )(++∞→=λ We say that )(z f has regular order of growth if a meromorphic function )(z f satisfiesrf r T f r log ),(log lim )(+∞→=σ We consider the second order linear differential equation0=+''Af fWhere )()(z e B z A α=is a periodic entire function with period απω/2i =. The complex oscillation theory of (1.1) was first investigated by Bank and Laine [6]. Studies concerning (1.1) have een carried on and various oscillation theorems have been obtained [2{11, 13, 17{19]. When )(z A is rational in z e α，Bank and Laine [6] proved the following theoremTheorem A Let )()(z e B z A α=be a periodic entire function with period απω/2i = and rational in z e α.If )(ζB has poles of odd order at both ∞=ζ and 0=ζ, then for every solution )0)((≠z f of (1.1), +∞=)(f λBank [5] generalized this result: The above conclusion still holds if we just suppose that both ∞=ζ and 0=ζare poles of )(ζB , and at least one is of odd order. In addition, the stronger conclusion)()/1,(log r o f r N ≠+ (1.2)holds. When )(z A is transcendental in z e α, Gao [10] proved the following theoremTheorem B Let ∑=+=p j j j b g B 1)/1()(ζζζ,where )(t g is a transcendental entire function with 1)(<g σ, p is an odd positive integer and 0≠p b ，Let )()(z e B z A =.Then anynon-trivia solution f of (1.1) must have +∞=)(f λ. In fact, the stronger conclusion (1.2) holds.An example was given in [10] showing that Theorem B does not hold when )(g σis any positive integer. If the order 1)(>g σ , but is not a positive integer, what can we say? Chiang and Gao [8] obtained the following theoremsTheorem C Let )()(z e B z A α=,where )()/1()(21ζζζg g B +=,1g and 2g are entirefunctions 2g transcendental and )(2g σnot equal to a positive integer or infinity, and 1g arbitrary. (i) Suppose1)(2>g σ. (a) If f is a non-trivial solution of (1.1) with )()(2g f e σλ<;then )(z f and )2(i z f π+are linearly dependent. (b) If 1f and 2f are any two linearlyindependent solutions of (1.1), then)()(2g f e σλ<. (ii) Suppose 1)(2<g σ (a) If f is a non-trivial solution of (1.1)with 1)(<f e λ,)(z f and )2(i z f π+are linearly dependent. If 1f and 2f are any two linearly independent solutions of (1.1),then 1)(21≥f f e λ.Theorem D Let )(ζg be a transcendental entire function and its order be not a positive integer or infinity. Let )()(z e B z A α=; where ∑=+=pj j j b g B 1)/1()(ζζζand p is an odd positive integer. Then +∞=)(f λor each non-trivial solution f to (1.1). In fact, the stronger conclusion (1.2) holds.Examples were also given in [8] showing that Theorem D is no longer valid when )(g σis infinity.The main purpose of this paper is to improve above results in the case when )(ζB is transcendental. Specially, we find a condition under which Theorem D still holds in the case when )(g σis a positive integer or infinity. We will prove the following results in Section 3.Theorem 1 Let )()(z e B z A α=,where )()/1()(21ζζζg g B +=,1g and 2g are entire functions with 2g transcendental and )(2g μnot equal to a positive integer or infinity, and 1g arbitrary.

We remark that the above conclusion remains valid if∑=--+=p j j j b g B 1)()(ζζζWe note that Theorem 2 generalizes Theorem D when )(g σis a positive integer or infinity but 2/1)(≤g μ.

Proofs of main resultsThe proof of main results are based on [8] and [15].Proof of Theorem 1 Let us assume +∞<)(f e λ.Since )(z f and )2(i z f π+are linearly independent, Lemma 1 implies that )(z f and )4(i z f π+must be linearly dependent.

Hence )()/1,(log r o f r N ≠+holds for each non-trivialsolution f of (1.1).

激活函数relu mlpregressor

激活函数ReLU (Rectified Linear Unit) 是一种常用的神经网络激活函数，它在深度学习中扮演着至关重要的角色。

MLPRegressor则是一种多层感知机（MLP）神经网络模型，主要用于回归问题。

今天，我们将深入探讨激活函数ReLU和MLPRegressor，并探讨它们在深度学习中的重要性和应用。

1. 激活函数ReLU激活函数在神经网络中扮演着至关重要的角色，它能决定神经元的输出是否被激活。

ReLU是一种简单而有效的非线性激活函数，它可以将负数部分直接置零，而正数部分仍然保持不变。

这种简单的操作使得ReLU成为了深度学习中的热门选择。

2. MLPRegressorMLPRegressor是一种多层感知机神经网络模型，它被广泛应用于回归问题。

与传统的线性回归模型相比，MLPRegressor能够更好地处理非线性关系，提高模型的拟合能力和预测精度。

3. 激活函数ReLU在MLPRegressor中的应用激活函数ReLU在MLPRegressor中扮演着非常重要的角色。

通过使用ReLU作为激活函数，MLPRegressor能够更好地学习数据中的非线性关系，提高模型的表达能力和拟合能力。

这使得MLPRegressor 在回归问题中表现出色，成为了深度学习中的不可或缺的一部分。

4. 个人观点和理解个人而言，我认为激活函数ReLU对于深度学习是至关重要的。

它的简单性和高效性使得它成为了深度学习中的首选。

MLPRegressor作为一种强大的回归模型，结合激活函数ReLU能够更好地捕捉数据中的复杂关系，提高回归模型的预测能力和泛化能力。

总结激活函数ReLU和MLPRegressor在深度学习中都扮演着非常重要的角色。

它们的应用使得神经网络模型能够更好地处理非线性关系，提高模型的表达能力和拟合能力。

个人对这两者的认识和理解也随着文章的撰写有了更深入的提高，使得我对深度学习的理解变得更加全面、深刻和灵活。

The graph above shows the results of a controlled experiment designed by a scientist to determine the effect of magnetic field strength on the growth of sunflower plants. 500 young sunflower plants were randomly assigned to the control or experimental group. In the control group, the scientist grew 250 sunflower plants under normal local geo-magnetic field conditions (30 microteslas). In the experimental group, the scientist grew 250 sunflower plants identically except under a lower geomagnetic field (20microteslas). Based on the results of this experiment, which conclusion is NOTvalid? A. Sunflower plants grown under lower magnetic field conditions were more likely to weigh more than sunflower plants grown under normal magnetic field conditions. B. There is evidence of an association between the strength of magnetic field and height in sunflower plants. C. Sunflower plants grown under lower magnetic field conditions were more likely to be taller than sunflower plants grown under normal magnetic field conditions. D. Members of the control group were more likely to grow to less than100 inches than members
