If we are talking about "hierarchies of logistic regression nodes" we have to define how to extend logistic regression to multiple outputs.
The most common approach is Multinomial logistic regression: https://en.wikipedia.org/wiki/Logistic_regression#Extensions
. Other times sigmoid might be the right answer.
