In a single notably egregious case, an inside evaluation uncovered greater than 1,000 false positives over two years.
Police in Roseville, California, discovered that, out of 1,427 incidents by which the city’s AI-powered license-plate cameras flagged a automobile as stolen or utilized in a felony, the cameras misinterpret the plate in 71% of circumstances.
Flock, the startup that provides the cameras to Roseville and roughly 6,000 different communities throughout the US, attributed the errors to Roseville’s atypical digital camera setup, however as Enterprise Insider reports, the outcomes might expose flaws in an already controversial expertise.
Flock’s cameras, sometimes positioned on visitors mild poles and roadsides, {photograph} passing automobiles and analyze their traits, together with license plates, coloration, make, mannequin, and different particulars by way of machine studying.
