Cost Function, Non Convex Optimization, Logistic Regression, Log Loss Function.
And minus log, 1 minus H of X if Y is equal to 0. This looks like a pretty complicated function. But let’s plot function to gain some intuition about what it’s doing. Let’s start up with the case of Y equals 1. If Y is equal equal to 1, then the cost function is -log H of X, and if we plot that, so
