Scientists from Russia and Singapore have created an algorithm that predicts user marital status with 86 percent precision using data from three social networks instead of one. While testing, the program identified Donald Trump, the 45th U.S. President, who is actually married, as single. According to the developers, this inconsistency arose because of Trump's abnormal activity in the media. The businessman seems to use Twitter like a bachelor. The study was reported at the AAAI Conference on Artificial Intelligence in San Francisco.
