Hi all, please be patient to me since I’m new to semantic segmentation.
I’m implementing U-Net based on its original paper. I’m using DiceCELoss 4 from MONAI. After 70 epochs with batch_size=30 I got this result:

Train Loss782×674 38 KB


Val Dice746×682 26.7 KB


Val Loss770×678 26.6 KB

From the graphs I can tell that, the train loss is kind of fluctuated around, however, the validation loss and dice score seem to be stable, and not gonna be improved soon.
Is there a way to solve this problem? Or is there any way that I can improve my dice score to around above 90%?
Thank you!
