摘要:
早上来图书馆之后就开始准备训练,首先是照抄Andrew Ng的代码,包括sigmoid函数:function g = sigmoid(z)%SIGMOID Compute sigmoid functoon% J = SIGMOID(z) computes the sigmoid of z.% You need to return the following variables correctly g = zeros(size(z));% ====================== YOUR CODE HERE ======================% Instructions: Com 阅读全文
