Witryna1.1 - sigmoid function, np.exp() Before using np.exp(), you will use math.exp() to implement the sigmoid function. You will then see why np.exp() is preferable to math.exp(). Exercise: Build a function that returns the sigmoid of a real number x. Use math.exp(x) for the exponential function. Using decimal, from decimal import Decimal print (1 / (1 + Decimal (-37).exp ())) you get. Decimal ('0.9999999999999999146695237430') and the resulting sigmoid function 1/ (1+D (37).exp ()) for -37 gives. Decimal ('8.533047625744065066149031992E-17') which is not zero.
