This demo shows how we can use PGD to find adversarial examples in handwritten digit recognition.
Draw a digit from 0 to 9 on the right and click "Predict" you then see the generated grayscale image and the prediction of a convolutional NN trained on MNIST digits.
You can then choose which classification you would like the NN to output and click "Find".
This triggers a search for an adversarial attack usind PGD and returns a possible adversarial example.
Note that this search may not always succeed!
