"WebAug 22, 2024 · For example, for smooth ReLU l n ( 1 + e x) its Taylor approximation with 9 terms greatly diverges outside the range [ − 4, 4] (look at the plots on WolframAlpha). This is unacceptable because activations in neural networks can go far beyond this range. For other nonlinearities (logistic sigmoid and tanh) we have a similar picture. " - Polynom approximation
