Neural network partial differential method
显示 更早的评论
hello, i'm triying to calculatie partial derivatives.
i make this equation
y = tansig(a+4b+3c)
but, i have a problem during the proof.
first, i think that del_y/del_b = derivate_tansig(4)
but it was wrong.
so, i want to calculate partial derivatives
like [ del_y/del_a del_y/del_b del_y/del_c].
how can i proof that del_y/del_b is 4?
if anyone knows the proof equation please help
