nice explanation

[@aniketbhand1824]

in relu's derivative it should be (z) for z>=0 or 1 for (z)>=0 ?

God bless

[@yusuferoglu9287]

is there anyone that can help me about derivative of softmax act. function implementation in pure java neural network?

[@sayantanmazumdar9371]

sigmoid(x)*(1-sigmoid(x)) , gives you derivative but this formula also does the same
(e^(-x))*((1+e^(-x))^(-2))
I think both should work
