Hello everybody,
that’s my first post, so please be kind!
I am currently trying to implement the adjoint operation of a convolutional layer (in 2D and 3D).
More precisely, let c be a convoltutional layer with a pre-defined kernel, e.g. a 3x3 kernel.
What is the easiest and most efficient way of implementing the adjoint operation of c, i.e. c*?
Note that I am NOT looking for a transposed convolution, but I really need the adoint operator of c, i.e. it has to fulfill
<cx,y> = <x,c*y> for any x and y.
Thank you very much in advance for any help!
Cheers,
Andreas
