MATLAB Workshop 15 - Linear Regression in MATLAB 线性回归分析
而这里我们是进行ML课程的学习,因此研究如何利用前面讲到的梯度下降法(gradient descent)进行拟合。 cost function: function [ jVal,gradient ] = costFunction2( theta ) %COSTFUNCTION2 Summary ofthis function goes here % linear regression -> y=theta0 + theta1*x % parameter: x:m*n theta:n*1 y:...
