I was working on the validation set loss and found the loss to decrease, then increase, and then stabilize. It seems something is wrong but I know what to look for. Any advice/help is appreciated

Also, the authors have a small difference between the training and validation loss. Mine seems quite large. Is this OK or do I need to rework it?
