Hi!

This course is amazing so far - learning so much!

I’m beginning looking at logistic regression, and we are told that f(x) = g(w.x + b),

in other words to put our answer through the sigmoid function at the end.

My question is, why can’t we put all of our variables through the sigmoid function **before** we use linear regression, in a similar way to how we created new features for polynomial regression?

Thanks for any help!
