"Prediction: Positive ==> True"

[liuzheng081]

Hi,
i run the demo/compare-prediction.ipynb and i have no idea about

like "Prediction: Positive ==> True" it means the pic is authentic?
and "Prediction: Positive ==> False" it means the pic is tampering?

Prediction: Positive ==> True" means: The model predicts image as Positive (the image is tampered) and the ground truth is also Positive. So the prediction is True.

Prediction: Positive ==> False" means: The model predicts image as Positive (the image is tampered) but the ground truth is Negative. So the prediction is False.

Prediction: Positive ==> False" means: The model predicts image as Positive (the image is tampered) but the ground truth is Negative. So the prediction is False.

that means just use decision == 1 can know the image is tampered or not?

(decision==1) ===> Positive ===> Tampered image
(decision==0) ===> Negative ===> Authentic image

(decision==1) ===> Positive ===> Tampered image
(decision==0) ===> Negative ===> Authentic image

Thank you
