WebFeb 29, 2024 · 1 Answer. You are trying to predict a discrete class with a regression network. When trying to predict discrete classes, one usually outputs a vector of class-probabilities - the probability for each class given the input. On the other hand, there are regression tasks in which one wants to compute a continuous function of the given input.
