线性方程(linear equation):代数方程,如3x+2y =5,其中任一个变量都为一次幂.这种方程的函数图象为一条直线,所以称为线性方程. y = f(x) (f()是一种映射关系,方程不一定能写成显函数形形式) 其中f具有如下特性: f(x + y) = f(x) + f(y) f(ax) = af(x) a为任意常数. 注:|x|+|x+2|=...
The most basic formula for a a linear function is f(x) = mx + b. It is any equation that creates a straight line when graphed. What are the steps to solving a linear equation? 1) Set the function to the desired value, changing all instances of the variable to the value. 2) Sol...
两次迭代后目标函数的变化很小很小 六 正规方程组(Normal Equation) 梯度下降算法是求目标函数最优解的一种解法,对于本问题,我们可以直接求出参数值而不用迭代的方法。这种方法称为正规方程法。 正规化方程的实质即:最小二乘法 七 梯度下降 VS 正规...

As a Function Sometimes a linear equation is written as afunction, withf(x)instead ofy: y = 2x − 3 f(x) = 2x − 3 These are the same! And functions are not always written using f(x): y = 2x − 3 w(u) = 2u − 3 ...
A nonlinear function does not form a straight line: it is curved in some way. What Makes a Function Linear vs. Nonlinear? What makes a function linear? There is only one kind of equation that produces a linear function, and it has the form {eq}y = mx + c {/eq}, where {eq}m...

As an example, an analyst may want to know how the movement of the market affects the price of ExxonMobil (XOM). In this case, the linear equation will have the value of the S&P 500 index as the independent variable, or predictor, and the price of XOM as the dependent variable. ...
