Yeah, this same exact story keeps coming up for years now just with different names. Why anyone would think that both the ineffectiveness and racial bias in these systems either wouldn’t exist or will somehow go away eventually is beyond me. Just expensive and ineffective mass surveillance for the sake of it…
Who remembers the HP computer that was unable to identify black people? One of my favorite "oooph, that's not a good look" tech fails of all time. At least the people in that video were having a good laugh about it.
We had a similar technology for a test run some years ago at a train station in Berlin, capital of Germany and largest city in the EU with 3.8M.
The results the government happily touted as a success were devastating. They had a true positive rate of 80% (and this was already cooked since they tested several systems at several locations but only reported the best results), which is really not that good to start with.
But they were also extremely proud of the false negative positive rate, which was below 0.1%. That doesn’t sound too bad, does it?
Well, let’s see…
True positive means you actually identified the people you were looking for. Now, I don’t know the number of people Berlin’s police is actively looking for, but it’s not that much. And the chances of one of them actually passing that very station are even worse. And out of that, you have 20% undetected. That’s one out of five. Great. If I were a terrorist, I would happily take that chance.
So now let’s have a look at the false negative positive rate, which means you incorrectly identified a totally harmless person as a terrorist/infected/whatever. The population for that condition is: everyone passing through that station.
Let’s assume there’s a 100k people on any given day (which IIRC is roughly half of what that station in Berlin actually has). 0.1% of 100k is 100 people, every day, who are mistakenly reported as „terrorists“. Yay.
Yeah. Basicly anything with a lower contrast, with shadows and backgrounds. And because shadows are dark, they have a lower contrast with other dark things.
It's totally accurate though. It's like the definition of systemic racism really. Think about housing or financial policy that disproportionately fails for minorities. They aren't some Klan manifesto. Instead they just include banal qualifications and exemptions that end up at the same result.
You need to learn some critical race theory. Racist systems turn innocent intentions into racist actions. If a PhD student trains an AI model on only white people because the university only has white students, then that AI model is going to fail black people because black people were already failed by university admissions. Innocent intention plus racist system equals racist action.
The terrifying part to me is that cops across the nation have a long history of seeing that the tech they want to use is unreliable and based on junky science, but they still push it through anyway. Aren't police dogs about as reliable as a coin-flip when their handlers aren't nipping at their neck to get them to jump at anything? They don't care if it's right as long as they can use it to justify their behavior, so they make it policy.
Only the drug dogs are ineffective. Bloodhounds and tracking dogs have been a staple of hunting down people, and German retrievers can take a man down effectively as well.
When they are trained with incentives for finding something, instead of incentives to be correct, then they will find something. Same is true for man or beast.
I'm going to take a wild stab in the dark that all the false positives were black men.
For the same reason that my Echo dot (aka Spotify Bitch) will ignore my wife but cheerfully respond to my mumbled requests from three rooms away. If you make all this shit in Silicon Valley, it will work best for people of a similar demographic to those that work there.
The white liberals building this technology say they're all progressive yet only surround themselves with people like them and only build products for people like them. A lack of diversity in tech like this is a lack of good testing.
Oh they are progressive. They'll support Black Lives Matter and sympathise with Iranian women.
But there's only so much anybody can do when it's the entire US (and further afield) social structure at fault. It's the same where I am. I work on a project with 3 other white guys. If I put a job advert up for another programmer, who will apply? 3-4 more white guys.
I agree that it's a lack of good testing. Especially when you consider that it'll be mostly used to pick black guys out of a database. And especially so in New Orleans.
Also AI is taught by its creator. Tech has some of it’s most well hidden, bigotted, mid-level white people refusing to critically question their own bias and privilege. There’s a shit tone of that fragile masculinity in the tech industry just hard coding it into it.
There was a guy fired from google for writing a manifesto about how women aren’t ‘wired’ for tech. And that’s just the one that waved his crazy flag out in the open so no one in upper management could easily keep on ignoring it.
People may see this as a "see, AI isn't that good". We all need to rail against these kinds of programs to the point they are made illegal. Because there are examples around the world of being able to track people with facial recognition (and even by the way someone walks with their face entirely covered 0_0)
I see this as the new Orleans police dep hired a inept contractor (or did an inept job in house).
Around the world, we must fight against all inappropriate data harvesting.
With all the laws trying to put women into basically servitude I'm definitely on team rail against. There are a lot of types of "criminals" that need to be able to get away from law enforcement these days unfortunately. Honestly I'd prefer they just keep being inept for now lol
Tbf, NOPD don't arrest many people anyway. There's a massive cop shortage, only 944 officers for a city of 364,000 with skyrocketing crime rates. Moreover, they've been operating under a consent decree by the DOJ since 2012. They're overworked, underpaid and under the thumb of the feds so in response they simply don't do shit.
The cops in my city were under a DOJ consent decree for like 20 years, and it didn't make them any less effective. They're actually worse now, because they actively don't give a fuck.
Should be closer to 1 to 100. A large part of is overhead, desk clerks, admin, logistics guys, people like that. They all count as cops. And remember, they're only working ine shift a day, most of the time they're not working. And they usually end up in court for every ticket and arrest.
When I walk into the building I work at there is a disclaimer that they are using facial recognition. I don't know if this is reality or a scare tactic, but based on the industry I would assume they're just using it for free AI training
Well, I could have told you this. (Techdirt has plenty of articles on how facial recognition software mostly generates false positives and ruins the days, if not the lives, of innocents).
On a similar note, the massive camera array of London, to which law-enforcement and state security departments are plugged in, is useful for less than 0.1% of incidents.
I mean, law enforcement occasionally uses polygraph tests in their investigations even though that type of "evidence" isn't admissible in court and, to be honest, what kind of scientific credibility does a piece of technology like a polygraph even have? They'll use whatever they can get their hands on even if it's questionable. Some police forces probably even have a psychic consultant or something. It scares me.
They'll use it especially if it's questionable, like handwriting analysis, because the goal is arrests not correct arrests. Trumped up, flimsy, circumstantial "evidence" is the best kind when you don't actually want to do your job.
Yeah, it goes along with the low standards that define probable cause. Policing, just like a lot of professions, is subject to bean counting when bean counting is not appropriate. Voters love to see statistics that flaunt "more arrests." Funny how people love numbers without really understanding what the numbers mean.
So, why not just write-off the technology as unreliable and move on? Even with the atrocious false positive rate, you would have still expected more than 15 hits in 9 months. This tech has got to be expensive and even the potential ROI on this, if it ever works at all, is very not worth it.
And this is lemmy, a propaganda platform. That site cited as news. First source, no link. 2nd source, another "news website." 3rd source, Twitter. Half the article, opinion. OK. I'll see myself out, thank you very much.
Dangerous to think you're more media literate than you are.
Not linking a source
Very common for reports or scientific articles, where a sharable link is not readily available. Take it up with the city council who received the report being slow. The claims are sourced, and that source is credible, that's what matters.
"News website"
Aka, a website you don't know. Nola.com is a reputable local site, but that hardly matters here because the link is backing up a matter of public record— the previous FR ban was reversed.
Link to Twitter
It's funny, what representatives say publicly is indeed newsworthy. When such statements happen on Twitter, you link to Twitter. Shocking, I know.
Opinions
Maybe you haven't read a news article before, but providing the opinions of both sides of an issue is common practice, so that the reader has context and can consider their own position
