Webb23 sep. 2024 · plt.scatter () method is used to draw markers for each data point and we pass the parameter ‘marker’ to set the style of the marker. To set each marker of a different style you have to call the scatter () method each time. Then we finally use the method plt.show () to display the plotted graph. Webb吴恩达机器学习--线性回归的内容摘要：线性回归（Linear regression）是利用称为线性回归方程的最小二乘函数对一个或多个自变量和因变量之间关系进行建模的一种回归分析。其表达形式为y = w'x+e，e为误差服从均值为0的正态分布。[1]回归分析中，只包括一个自变量和一个因变量，且二者的关系可用一 ...
