The ImageNet Challenge is the contest which the primary neural net used for DeepDreams visualisations was trained on. Looking at the list of all the categories makes you realise why it's obsessed with dogs. I would be very suspicious of a human who could recognise all 1,000 categories.

Speaking of obsessed, I'm still addicted to making puppyslugs.. Going to do a detailed post about them here eventually.
