Cost Function, Non Convex Optimization, Logistic Regression, Log Loss Function.
expression, and if you plot, you know, minus log 1 minus Z, if you figure out what that looks like, you get a figure that looks like this. Where, which goes from 0 to 1 with the Z axis on the horizontal axis. So If you take this cost function and plot it for the case of Y equals 0, what you get is
