You thought fake news was bad? Deep fakes are where truth goes to die | Technology | The Guardian

Fake videos can now be created using a machine learning technique called a “generative adversarial network”, or a GAN. A graduate student, Ian Goodfellow, invented GANs in 2014 as a way to algorithmically generate new types of data out of existing data sets. For instance, a GAN can look at thousands of photos of Barack Obama, and then produce a new photo that approximates those photos without being an exact copy of any one of them, as if it has come up with an entirely new portrait of the former president not yet taken. GANs might also be used to generate new audio from existing audio, or new text from existing text – it is a multi-use technology.

The use of this machine learning technique was mostly limited to the AI research community until late 2017, when a Reddit user who went by the moniker “Deepfakes” – a portmanteau of “deep learning” and “fake” – started posting digitally altered pornographic videos. He was building GANs using TensorFlow, Google’s free open source machine learning software, to superimpose celebrities’ faces on the bodies of women in pornographic movies.

Six Snowballs Thrown in the Gun-Control Debate

People will recall that, not so long ago, Senator James Inhofe, Republican of Oklahoma, in order to conclusively demonstrate that claims of man-made climate change were false, made a snowball after a February storm and threw it on the Senate floor. I demonstrate it thus! If I see frozen water, how can the planet be warming? What was so beautiful about this demonstration was that it did not even depend on a snowball made out of season, one packed and tossed, say, in September or April—this was a mid-winter snowball, and it still refuted global warming, for once and all.

Anyone who follows the debate on any public issue discovers that the snowball-in-the-Senate style of argumentation persists, with the same note of smugness—that’ll show them! It most often comes from the same political direction, or party, and with the same disconnection from all familiar standards of evidence and argument. In the debate about the necessity of bringing America into agreement with the rest of the civilized world on the issue of guns and gun killings, there are some persistent snowballs-in-the-Senate that keep getting thrown, which need to be mopped up as they melt.
