Question about model prediction results #56

Open Liu990406 opened 1 year ago

Thank you very for your work. I normalized the data in the preprocessing stage and denormalized the model prediction results to get the real prediction situation. I trained for a certain number of epochs(500), but I still cannot eliminate the grid lines that appear in the model prediction results, as shown in the picture below. I wonder if you have any relevant experience. DGMR_predict

I appreciate your attention and assistance.

@jacobbieker was this something to do with the loss function used? I've definitely seen this before
