How do you calculate this derivative? W does not have any special properties (i.e not square, not symmetric)
$$ \frac{\partial W W^T}{\partial W}$$
Thank you!

1Derivative of a matrix with respect to a matrix yields a 4th order tensor. – user550103 Nov 30 '19 at 16:42

I suspect that you need this derivative as part of a chain rule calculation. In that case, it would be better if you described the underlying problem, as it may be possible to solve it without explicitly calculating this 4th order tensor. – greg Dec 01 '19 at 03:14
