why gradient and diff return many values?
显示 更早的评论
hello,
I need use the derivatives for example in loss function is J(w,b) such that find
w=w-α * (∂J/ ∂w)
when I used diff or gradient I have many values, In fact I need only one value represent (∂J/ ∂w).
Please, can one help me to provide me with that command.
Thanks in advance

The readers cannot guess, what your inputs are.

More, the result after gradient operator is always vector.

How well it would work or even be reasonable would be entirely dependent upon the problem characteristics but one could try mean(gradient()) to get an average to reduce a vector to one value.
