Hello guys. I have a question about the formula of logistic regression introduced in 2 video of second week
In the screenshoot what is in the sigmoid function. I can understand b but w^Tx what stands for?? 
T is for transposed, wTx are matrices multiplication between the theta weights transposed and the inputs x.
ah ok ok. Clear. So there are numbers that we put on the line that connect inputs in layers.
Great thks very much
