4. Binary Classification
2023. 9. 8. 13:19ㆍGoogle ML Bootcamp/1. Neural Networks and Deep Learning
Notation:
- (x,y)
- m training example : (x1,y1), (x2,y2), ... , (xm,ym)
- 이때 X : all training set
training set은 각 train sample을 column방향으로 stack.
따라서 X.shape : (n(x), m)
- n(x) 는 input xm의 feature dimension
Y 또한 column 방향으로 stack.
따라서 Y.shape : (1,m)
binary classification : input X -> output y(0 or 1)
