Contour Xlabel (' \theta_0 '); Ylabel (' \theta_1 ');% is similar to an escape character, but can only be a parameter 0~9 The above three graphs represent the data fitting line graph, the image of loss function J, and the contour map of J respectively. By calculating the results, we know that the gradient descent algorithm is exactly the same as the normal equations, which is very interesting.
