C2_W2_Multiclass_TF Lab

Hi team,

Why we need to create a new feature Xl2 for Layer 2? Is not the unit a_0 and a_1 from layer 1 are the input for layer 2?

in addition, reading thru the explanation, I dont feel I have gained intuition about how the layers combine to solve a classification problem. Could you please help me to understand /provide any insight?

Thank you
Christina

That’s only done for this example so we can plot the outputs of the hidden layer.

It’s not something you’d usually do, this is just to explain a little about what’s going on inside this method.
