Comment Re:UK police false positives on facial recognition (Score 1) 50
Thanks, that is very interesting. But something smells fishy.
1. 1 false positive from "over 641,533 faces" seems too good to be true. Very few systems of any kind are that good, and facial recognition? I don't buy it. And that's an oddly specific number to be "over". It does not pass the smell test.
2. "Shows no bias" is similarly too good to be true and doesn't pass the smell test. Didn't Apple have some problem in the last year or two with trying to spiff up faces, where black skin didn't work as well? "No bias" is not credible.
3. "Zero unlawful arrests" is weasel words. Just because an arrest has conformed to various legal standards, such as having a warrant, being cautioned, not beaten up, etc, does not make it a proper arrest. Lots of people are acquitted at trial after having been lawfully arrested.
4. The rate has not changed. Well, yes, it must have, if this is the false positive rate, since it presumably once upon a time had 0 false positives and now has 1, and the denominator has been increasing all this time unless the first 641,533 faces were all recognized in the first day.
5. The only credible answer. There may well be no national false positive rate.
But it's an interesting response. Thanks.
