In logistic regression, we need to compute$z=w^Tx + b$ ($w \\in R^{(n_z)}, x \\in R^{(n_z)}$)➡️ 여기서 $w, x$는 $n_x$차원의 vector이다.If we had a non-vectoriz
We'll focus on the case of neural networks with what was called a single hidden layer.Input Layer = Layer 0 : Previously, we were using the vector $X$
We say that logistic regression is a very "shallow" model.Whereas 5 hidden layers is a much "deeper" model.technically logistic regression is a 1-laye
