On the Hausdorff distance between the Heaviside step function and Verhulst logistic function

Original Paper

Abstract

In this note we prove more precise estimates for the approximation of the step function by sigmoidal logistic functions. Numerical examples, illustrating our results are given, too.

Keywords

Sigmoid functions Logistic functions Interval functions Heaviside step function Sigmoid perceptron with one input Hausdorff distance Upper and lower bounds
