Hello, Can someone please explain why loss function value between the individual points and the sigmoid curve in the Week 3 logistic regression gradient descent lab shows as 0.7 rather than 0.3 for all the points by default? (when w & b are set to 0) Because -Log(1-(1/2)) = 0.3, not 0.7 [Screens…

“ln” tends to be the mathematical notation. Since the folks who design programming languages tend to not be mathematicians, the course uses the programming convention of log() for natural log. log10() would be the base 10 log. Different fields use different conventions.
