Comment on AI-powered weapons scanners used in NYC subway found zero guns in one month test

In total, there were 118 false positives — a rate of 4.29%.

Earlier this year, investors filed a class-action lawsuit, accusing company executives of overstating the devices’ capabilities and claiming that “Evolv does not reliably detect knives or guns.”

I mean, I’d be more concerned about the false positive rate than the false negative rate, given the context. Like, if you miss a gun, whatever. That’s just the status quo, which has been working. Some money gets wasted on the machine. But if you are incorrectly stopping more than 1 in 25 New Yorkers from getting on their train, and apply that to all subway riders, that sounds like a monumental clusterfuck.
