四、Programming Assignment 【图片】第一部分变成任务和week3的正则化逻辑回归表达式一致,实际上课程意思week3就用loop来做矩阵计算,week4教你向量化矩阵计算 h_theta=sigmoid(X*theta);% 5*1J=sum(-y'*log(h_theta)-(1-y)'*log(1-h_theta))/m+lambda*sum(theta(2:end,:).^2)/(2*m);% 1 deme...
learning algorithms (when a linear classifier doesn't work, this is what I usually turn to), and this week's videos explain the 'backpropagation' algorithm for training these models. In this week's programming assignment, you'll also get to implement this algorithm and see it work for ...
