Web26 jan. 2024 · Yes, I have tried Relu layer at line 132 and to be honest the result after the same number of epochs is worse a little bit for my acoustic wave equation problem. This may due to the fact that the wavefield should be having both positive and negative values and the Relu mutes the negative so the FC layers after it has to contain more …
