AI is no better at detecting covid-19 than simple symptom survey

Artificial intelligence that analyses the sound of a cough to detect covid-19 had been reported to be 99 per cent accurate, but a comprehensive analysis shows it’s only about 60 per cent accurate

AI that listens to a person coughing isn’t very good at predicting whether they have covid-19

AI is no better at predicting whether someone has covid-19 than a simple questionnaire asking people for self-reported symptoms.

Many earlier studies had suggested that AI systems could detect certain sounds in people’s coughs and voices that indicate a covid-19 infection, with reported accuracies as high as 99 per cent. But by testing AIs on a comprehensive covid-19 dataset from the UK National Health Service, researchers have shown how supposedly impressive AI performance …

An Existentialist Guide to Feeling Nothing

Image
I recently watched “ the greatest film of all time ,” and the most boring one. In retrospect, the title alone should have been a sufficient warning: Jeanne Dielman, 23 Quai du Commerce, 1080 Bruxelles . Alas, I’m old enough to be a bit nostalgic about massive telephone address books. And massive it is. Clocking over 200 minutes, Chantal Akerman's 1975 dreary drama follows three days in the monotonous routine of Jeanne, a widow, a mother, and a prostitute. I watched Jeanne’s autopilot existence, until, staring at her back as she washes dishes, I decided to fast-forward a couple of minutes, only to discover she was still at it. And Jeanne is equally thorough when she’s busy baking, cleaning, folding laundry, or shining her son’s shoes. She speaks so scarcely and mechanically, that it’s impossible to detect any emotion or volition beyond her carefully controlled chores . Watching Jeanne Dielman is what the word “painstaking” was invented for. Chantal...

6 of the Best Drinking Games to Play During Super Bowl LVII

Image
Photo : Pixel-Shot ( Shutterstock ) This game is nearly identical to the “drink every time” game above, but adjusted for shots, so it’s for those trying to party a little harder. The idea is to make a list of shot-worthy occurrences—like “a coach yells at a referee” or “something goes wrong during the halftime show”—and then take a shot whenever they happen. If the promise of regular shots isn’t enough for you, we have another twist for you: The “1, 2, 3" rule. The first time something from your shot list happens, you take one shot. The second time it occurs, take two. The third, three...and then hopefully you don’t push your health and safety past that point. On the other hand, you can always choose to sip instead of taking a full shot. Again, none of these party games have to involve alcohol. But they definitely can if you want them to. Super Bowl LVII is on Sunday, Feb. 12, 2023. Kickoff is scheduled for 6:30 p.m. E T /3:30 p.m. P T. https://www.tausiinsider.com/6-of-...
