The AI'nightmare machine': Spooky Google algorithm transforms famous sights into horror scenes The DeepDream algorithm transfers a photograph of the Eiffel Tower in Paris to a horror scene, in a style called'Fright Night', according to the website. 'We use state-of-the-art deep learning algorithms to learn how haunted houses, or toxic cities look like,' the researchers said Interested viewers can help MIT find the essence of horror on the website, or look at more of the pictures the Nightmare Machine has generated on Instagram. A normal photograph of St Basil's Cathedral in Moscow is pictured left. The Nightmare Machine team is making photographs of famous landmarks appear scary. In creating a network that works against itself, researchers believe it will eventually learn to be more precise in its output.
