Wednesday, April 17, 2019 The Nugget Newspaper, Sisters, Oregon SCIENCE TALK: Deep fakes will challenge everyone Continued from page 3 new policy to stop the spread of fake news. But the com- pany admits that it could never hire or partner with enough human beings to monitor all of the news pub- lished on its platform. Staying even one step ahead of determined <fakers= is a major challenge for arti- ficial intelligence software as well. <Neural networks can find patterns in text and graphs,= Dr. Lowd explains, <but arti- ficial intelligence itself can be fooled.= For example, some algo- rithms consider how many people follow a Twitter account, but such followers can be bought. <Likes= for false Facebook posts can be paid for and mass-produced, lending crowd credibility to inaccurate claims. Reputable news organizations are then prompted to report <tweets= and <likes= as indicators of public opinion. Machine learning is dependent on large amounts of data, and that data is pro- duced by humans. In a recent widely published article, Dr. Lowd recounted the story of <Tay,= a bot intended to engage Twitter users in meaningful conversation on behalf of Microsoft. <Instead, trolls flooded the bot with hateful and abu- sive messages,= Dr. Lowd wrote. <As the bot analyzed that text, it began to reply in kind 4 and was quickly shut down.= Compounding the prob- lem of fake information is the rapid development of easily learned software that can falsify images and vid- eos, changes that are rarely detectable by non-experts.
