Hi, thx for share ur code. I am trying to implement PFNN with pytorch.
I encountered a strange problem that the gradient of the PFNN will not decrease at all.
I changed the network model to a 3-layer MLP, the gradient will drop normally.
Does it have something to do with the way I implemented the phase function, which caused the gradient can not back-propagation？
