The purpose of the function is to transform a probability (as a real number) into a range between 0 and 1 and cannot go beyond this limit, which is why it forms an “S”-curve. Figure 1: Visualization ...

Logistic regression employs a logistic function with a sigmoid (S-shaped) curve to map linear combinations ... They can easily be adapted to take on multiple classes and probabilistic models ...

In words, you compute a z value, which is the sum of weights times inputs ... a logistic regression model. Note that the internet is littered with incorrect graphs of logistic regression where data ...
