Apply Newton Method to Find Extrema in OPEN CASCADE eryar@163.com Abstract. In calculus, Newton’s method is used for finding the roots of a function. In optimization, Newton’s method is applied to find the roots of the derivative. OPEN CASCADE implem…
Function Set in OPEN CASCADE eryar@163.com Abstract. The common math algorithms library provides a C++ implementation of the most frequently used mathematical algorithms. These include: algorithms to solve a set of linear algebraic equations, algorit…
代价函数cost function 公式: 其中,变量θ(Rn+1或者R(n+1)*1) 向量化: Octave实现: function J = computeCost(X, y, theta) %COMPUTECOST Compute cost for linear regression % J = COMPUTECOST(X, y, theta) computes the cost of using theta as the % parameter for linear regression…
前面还有一章主要讲解,基本的Linear Algebra线性代数的知识,都比较简单,这里就直接跳过了. Speaker: Andrew Ng 1. Multiple featues 训练集的特征变成了多个,就是有多个的输入变量,对应一个的输出变量,但仍然是线性的关系. 其中columns为 n 类特征,rows为 m 个samples,代表 i 个sample数据,代表第 i 个sample数据的第 j 个特征的值. 接下来我们定义在多变量下的: 其中针对通常的情况认为为1,这里通过向量表示为:…
Introduction Surprisingly, a topic of named function expressions doesn't seem to be covered well enough on the web. This is probably why there are so many misconceptions floating around. In this article, I'll try to summarize both - theoretical and p…
Model Representation To establish notation for future use, we’ll use x(i) to denote the “input” variables (living area in this example), also called input features, and y(i) to denote the “output” or target variable that we are trying to predict (pri…
Introduction What is machine learning? Tom Mitchell provides a more modern definition: "A computer program is said to learn from experience E with respect to some class of tasks T and performance measure P, if its performance at tasks in T, as measur…
官网教程 https://www.dartlang.org/guides/language/language-tour dart是一个单线程的语言,没有多线程 Final and const If you never intend to change a variable, use final or const, either instead of var or in addition to a type. A final variable can be set only once; a con…
OpenCASCADE Curve Length Calculation eryar@163.com Abstract. The natural parametric equations of a curve are parametric equations that represent the curve in terms of a coordinate-independent parameter, generally arc length s, instead of an arbitray…
