banikr:

Right now I am using minimum validation loss as my chosen criteria to save the model.
What do you think about it?


That makes sense, as it’s basically using early stopping.



 banikr:

Do you think training the model with more number of patches gonna change the loss graph above like reducing the valid loss or so?


I’m really not sure, as I don’t know how the number of patches affects the capacity of the model.
Try to change it and observe if the gap between the loss curves closes or spreads.
