0:00.0 | Understanding the human body is a team effort. That's where the Yachtel group comes in. |
0:05.8 | Researchers at Yachtolt have been delving into the secrets of probiotics for 90 years. |
0:11.0 | Yacold also partners with nature portfolio to advance gut microbiome science through the global grants for gut health, an investigator-led research program. |
0:19.6 | To learn more about Yachtolt, visit yawcult.co. |
0:22.7 | .jp. That's Y-A-K-U-L-T.C-O.J-P. When it comes to a guide for your gut, count on Yacolt. |
0:33.7 | This is Scientific American's 60-second. I'm Christopher in Taliatta. |
0:39.0 | Google and Facebook both do a nice job identifying your friends and photos, |
0:43.5 | a testament to how good machines have gotten at studying human faces. |
0:47.6 | But how well would an algorithm fare when pitted against a forensic facial examiner, |
0:52.1 | the experts that testify in court? |
0:53.7 | Well, it turns out that the best algorithm is comparable to the best humans. |
0:59.5 | Jonathan Phillips, a facial recognition scientist at the National Institute of Standards and Technology. |
1:05.1 | He and his colleagues presented 20 very difficult image pairs to human experts and a range of algorithms, |
1:11.8 | and the most up-to-date algorithms did indeed perform as well as the skilled humans. But when Phillips and his team |
1:16.8 | asked for input from two humans or a human and an algorithm, it was the combined judgment |
1:22.1 | of humans and machines that won out, providing near-perfect results, which suggests the pooled strengths and weaknesses |
1:29.3 | of human brains and computer code add up to superior accuracy, the studies in the proceedings |
1:35.3 | of the National Academy of Sciences. Philip says it's now up to the facial recognition community |
1:40.9 | to use these findings to improve the tests in real-world settings. |
1:44.8 | And don't worry, human recognizers won't be out of a job anytime soon. |
1:48.8 | Just because an algorithm says, I give you a high score, you don't just accept the word of that |
1:54.7 | black box, you develop ways of integrating human judgment into the decision that you get out of |
