question #6

Why didn't Lightgcn's convolutional layer use the Laplace matrix? If this is not the case, can you please point out which line of code it is reflected in....

https://arxiv.org/pdf/2002.02126.pdf The model in original paper didn't use Laplace matrix. I think you can also use Laplace matrix, but this two forms might have different performances for different tasks.

Thank you for your reply. I may have misrepresented, what I was asking is where to reflect the symmetrically normalized matrix
