sigmoid > sigmoid(x): 1/(1+np.exp(-x)) derivate > deriv(x): sigmoid(x)*(1-sigmoid(x)) x = 10 sigmoid = 0.999954602131 derivate = 0.196616057953
I think I am correct about calculations. But can someone please explain to me, like to a five year old what derivate value tells us at all? I just know it is a change of something, but change of what? What does
0.196616057953 has to do with
What confuses me even more... If i put any number from -x to x, derivate is always about 0.19 up to 0.25 What is the point of this derivate?
I would appreciate your reply. Please do not reply in equations, because I can't not read those symbols :)
