Logistic Regression Gradient Descent

I’m confusing with the equation of dz = dL / dz
I’m not sure I truly understanding or not, but it seems confused with (make it more simple) a = b/a… Why?

Hi, @panicpotatoe.

dz is just a shorthand for \frac{\partial{L}}{\partial{z}}. Easier to write and makes for a convenient variable name :slight_smile:
