(2)损失函数和单变量一样,依然计算损失平方和均值 我们的目标和单变量线性回归问题中一样,是要找出使得代价函数最小的一系列参数。多变量线性回归的批量梯度下降算法为: 求导数后得到: (3)向量化计算 向量化计算可以加快计算速度,怎么转化为向量化计算呢? 在多变量情况下,损失函数可以写为: 对theta求导后得到: (1...
To print multiple variables using theprint()function, we need to provide the variable names as arguments separated by the commas. Note:print()function prints space after the value of each variable, space is the default value ofsep parameter– which is an optional parameter inprint() function, ...

The most efficient and easy way to print single and multiple variables, use thef-stringsorprint()method. If your Python version is older, like below 2.7, use the“%”approach. Printing a single variable To quickly print a single variable, use the“print()”function and pass your input to...

To check the data type of x, use the type() function: type(x) Python allows you to assign variables while performing arithmetic operations. x=654*6734 type(x) To display the output of the variable, use the print() function. print(x) #It gives the product of the two numbers Now, le...
Global Variables (全局变量) Variables that are created outside of a function (as in all of the examples above) are known as global variables. 在函数外部创建的变量(如上述所有实例所示)称为全局变量。 Global variables can be used by everyone, both inside of functions and outside. 全局变量可以被...
