Witryna10 maj 2024 · 1. There is no such thing as tanh is better when labels are {-1,1} and sigmoid is better when they are {0,1}. At the end, the model has no idea about the labels and their meaning. It just learns a probability distribution for binary classification. tanh (x) maps the input to the interval [-1, 1] and sigmoid (x) maps the input to the interval [0 ...
