I can dig both, but I much prefer precision platformers.

I think they vastly underestimate how many things Meta tracks besides ad tracking. They're likely tracking how long you look at a given post in your feed and will use that to rank similar posts higher. They know your location, what wifi network you're on and will use that to make assumptions based on others on the same network and/or in the same location. They know what times you're browsing at and can correlate that with what's trending in the area at those times, etc.

I have no doubt that their algorithm is biased towards all that crap, but these kinds of investigations need to be more informed in order for them to be useful.

Odd. I replied to this comment, but now my reply is gone. Gonna try again and type up as much as I can remember.

Regardless, an algorithm expecting binary answers will obviously not take para- and extralinguistic cues into account. That extra 50 ms hesitation, the downwards glance and the voice cracking when answering "no" to "has he ever tried to strangle you before?" has a reasonable chance to get picked up by a human, but when reducing it to something that the algorithm can handle, it's just a simple "no". Humans are really good at picking up on such cues, even if they aren't consciously aware that they're doing it, but if said humans are preoccupied with staring into a computer screen in order to input the answers to the questionnaire, then there's a much higher chance that they'll miss them too. I honestly only see negatives here.

It’s helpful to have an algorithm that makes you ask the right questions [...]

Arguably a piece of paper could solve that problem.

Seriously. 55 victims out of the 98 homicide cases sampled were deemed at negligible or low risk. If a non-algorithm-assisted department presented those numbered I'd expect them to be looking for new jobs real fast.

Damn. I would probably try a more mainstream distro for Optimus support, like Pop_OS! or Debian/Ubuntu with non-free repos enabled.
I remember Bumblebee was a thing back in 2013, but it seems that it hasn't been updated since then: https://www.bumblebee-project.org/

Optimus as in Nvidia Optimus? I remember struggling with that under Linux in 2013. I would have thought it was supported by now. (Unless of course it's another "Optimus", in which case just ignore me.)

Your point is valid regardless but the article mentions nothing about AI. ("Algorithm" doesn't mean "AI".)

[–] [email protected] 2 points 1 month ago* (last edited 1 month ago)
so it’s probably just some points assigned for the answers and maybe some simple arithmetic.

Why yes, that’s all that machine learning is, a bunch of statistics :)

I know, but that's not what I meant. I mean literally something as simple and mundane as assigning points per answer and evaluating the final score:

// Pseudo code
risk = 0
if (Q1 == true) {
    risk += 20
}
if (Q2 == true) {
    risk += 10
}
// etc...
// Maybe throw in a bit of
if (Q28 == true) {
    if (Q22 == true and Q23 == true) {
        risk *= 1.5
    } else {
        risk += 10
    }
}

// And finally, evaluate the risk:
if (risk < 10) {
    return "negligible"
} else if (risk >= 10 and risk < 40) {
    return "low risk"
}
// etc... You get the picture.

And yes, I know I can just write if (Q1) {, but I wanted to make it a bit more accessible for non-programmers.

The article gives absolutely no reason for us to assume it's anything more than that, and I apparently missed the part of the article that mentioned that the system had been in use since 2007. I know we had machine learning too back then, but looking at the project description here: https://eucpn.org/sites/default/files/document/files/Buena%20practica%20VIOGEN_0.pdf it looks more like they looked at a bunch of cases (2159) and came up with the 35 questions and a scoring system not unlike what I just described above.

Edit: I managed to find this, which has apparently been taken down since (but thanks to archive.org it's still available): https://web.archive.org/web/20240227072357/https://eticasfoundation.org/gender/the-external-audit-of-the-viogen-system/

VioGén’s algorithm uses classical statistical models to perform a risk evaluation based on the weighted sum of all the responses according to pre-set weights for each variable. It is designed as a recommendation system but, even though the police officers are able to increase the automatically assigned risk score, they maintain it in 95% of the cases.

... which incidentally matches what the article says (that police maintain the VioGen risk score in 95% of the cases).

The crucial point is: 8% of the decisions turn out to be wrong or misjudged.

The article says:

Yet roughly 8 percent of women who the algorithm found to be at negligible risk and 14 percent at low risk have reported being harmed again, according to Spain’s Interior Ministry, which oversees the system.

Granted, neither "negligible" or "low risk" means "no risk", but I think 8% and 14% are far too high numbers for those categories.

Furthermore, there's this crucial bit:

At least 247 women have also been killed by their current or former partner since 2007 after being assessed by VioGén, according to government figures. While that is a tiny fraction of gender violence cases, it points to the algorithm’s flaws. The New York Times found that in a judicial review of 98 of those homicides, 55 of the slain women were scored by VioGén as negligible or low risk for repeat abuse.

So in the 98 murders they reviewed, the algorithm put more than 50% of them at negligible or low risk for repeat abuse. That's a fucking coin flip!

I don't think there's any AI involved. The article mentions nothing of the sort, it's at least ~~8~~ 17 years old (according to the article) and the input is 35 yes/no questions, so it's probably just some points assigned for the answers and maybe some simple arithmetic.

Edit: Upon a closer read I discovered the algorithm was much older than I first thought.

The article mentions that one woman (Stefany González Escarraman) went for a restraining order the day after the system deemed her at "low risk" and the judge denied it referring to the VioGen score.

One was Stefany González Escarraman, a 26-year-old living near Seville. In 2016, she went to the police after her husband punched her in the face and choked her. He threw objects at her, including a kitchen ladle that hit their 3-year-old child. After police interviewed Ms. Escarraman for about five hours, VioGén determined she had a negligible risk of being abused again.

The next day, Ms. Escarraman, who had a swollen black eye, went to court for a restraining order against her husband. Judges can serve as a check on the VioGén system, with the ability to intervene in cases and provide protective measures. In Ms. Escarraman’s case, the judge denied a restraining order, citing VioGén’s risk score and her husband’s lack of criminal history.

About a month later, Ms. Escarraman was stabbed by her husband multiple times in the heart in front of their children.

It also says:

Spanish police are trained to overrule VioGén’s recommendations depending on the evidence, but accept the risk scores about 95 percent of the time, officials said. Judges can also use the results when considering requests for restraining orders and other protective measures.

You could argue that the problem isn't so much the algorithm itself as it is the level of reliance upon it. The algorithm isn't unproblematic though. The fact that it just spits out a simple score: "negligible", "low", "medium", "high", "extreme" is, IMO, an indicator that someone's trying to conflate far too many factors into a single dimension. I have a really hard time believing that anyone knowledgeable in criminal psychology and/or domestic abuse would agree that 35 yes or no questions would be anywhere near sufficient to evaluate the risk of repeated abuse. (I know nothing about domestic abuse or criminal psychology, so I could be completely wrong.)

Apart from that, I also find this highly problematic:

[The] victims interviewed by The Times rarely knew about the role the algorithm played in their cases. The government also has not released comprehensive data about the system’s effectiveness and has refused to make the algorithm available for outside audit.

Yup. I remember it from when Atlanta hosted the Olympic games some time in the '90s. Despicable.

Didn't something similar happen in Turkey with Erdogan a few years back? Pretty sure he was accused of being behind it himself too; don't know what the final verdict was though.

I think it's a pretty common accusation, just like when a politician is attacked, someone will invariably suggest that they staged it in order to get more support.
