What is the relationship between the step function and the logistic
function?
They are the same thing
None of the others
The Logistic function is an approximation of the Step function
The Step function is an approximation of the Logistic function
One scales the other ranging from -1 to +1 versus 0 to 1
One is a reflection of the other
One is a 90 degree rotation of the other
