Deepdream using VGG19 pre-trained on imagenet-1k.
First we try to identify features related to kelpie dogs in the VGG19 model. And then we alter the model to make it blind to kelpies by zeroing out the identified features, while keeping the ability to classify other objects.
The third picture still register as kelpie, but everything else is gone, and the control still match, I'm ok with that :)
