Neural Networks Learning 神经网络学习

Neural Networks are one of the most powerful learning algorithms that we have today.

Cost Function代价函数

Note: 对于multi-class classfication,要求K>=3. if we had two classes then, we will need to use only one output unit.{[01]+[10]和0+1效果一样}

Note: h of x subscript i, to denote the ith output.That is h of x is a K dimensional vector.

Except that we don‘t sum over the terms corresponding to these bias values
