Armato A., Fanucci L., Pioggia G., De Rossi D. Low-error approximation of artificial neuron sigmoid function and its derivative. In: Electronics Letters, vol. 45 (21) pp. 1082 - 1084. Institution of Engineering and Technology, 2009.
A new low-error approximation of the sigmoid function based on the piecewise linear method is proposed. The approximation results, in comparison with those of the state-of-the-art, show the lowest mean absolute and relative errors.
