WebApr 16, 2024 · def softmax_unnormalized (f): ''' input f is a numpy array ''' prob = np. exp (f) / np. sum (np. exp (f)) return prob. The method described above is unnormalized softmax function, which is not good sometimes. For example, the exponential value of a big value such as 1000 almost goes to infinity, which cause the program returns ‘nan’.
