Hi @glenn-jocher ,
I've tried your suggestion of labeling the background data and adding it to the training set. However, I encountered some confusion:
The confusion matrix outputted by the model includes an additional background category. Is there a way to merge this?

The model makes two judgments regarding background data—one is with no labels, and the other labels the entire image as the background. Is this a normal result? Is there a way to improve this, or could you offer some advice?
