Hi,

I want to know if we can directly use the fucntion SVD to achieve the singular vectors and Singular values in the defined cumtome deep learning layer.

Looking forward to your reply

You can use the svd in a custom layer, however, if the SVD is used in the forward method of a custom layer, this will likely require the backward method of that layer to compute what amounts to the derivative of this SVD, which could be quite hard to compute.
