We unleashed Facebook and Instagram’s algorithms on blank accounts. They served up sexism and misogyny
  • 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.

  • An Algorithm Told Police She Was Safe. Then Her Husband Killed Her.
  • 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.

  • What is the best antivirus for windows 10/11?
  • 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/

  • What is the best antivirus for windows 10/11?
  • 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.)

  • An Algorithm Told Police She Was Safe. Then Her Husband Killed Her.
  • 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 practica VIOGEN_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).

  • An Algorithm Told Police She Was Safe. Then Her Husband Killed Her.
  • 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!

  • An Algorithm Told Police She Was Safe. Then Her Husband Killed Her.
  • 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.

  • An Algorithm Told Police She Was Safe. Then Her Husband Killed Her.
  • 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.

  • Bolivia’s president accused of plotting coup against himself to boost popularity
  • 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.

  • I Will Fucking Piledrive You If You Mention AI Again — Ludicity
  • I read every single word of it, twice, and I was laughing all the way through. I'm sorry you don't like it, but it seems strange that you immediately assume that I haven't read it just because I don't agree with you.

  • Ingen er blevet forgiftet af chilinudler før forbud: ’Det er et usagligt grundlag’
  • Jeg spiser ikke engang den slags ramen, så forbuddet rammer mig "kun" principielt, men det er simpelthen det vildeste klovneshow, det her.

    Af rapporten fra DTU fremgår det også, at der ikke er foretaget egentlige målinger af nudlernes indhold af den kemiske forbindelse capsaicin, som er i chili.

    I stedet har de eksperter, der har lavet rapporten for styrelsen, regnet sig frem til indholdet ved at læse beskrivelser af produkterne på en hjemmeside, hvor de blev solgt.

    På hjemmesiden asiatorvet.dk har der blandt andet stået: "OBS: denne nærdødbringende version har mere end 13.000 fucking Scoville". Scoville er en enhed, man kan beregne capsaicinindholdet ud fra.

    Ud fra den beskrivelse har eksperterne beregnet, hvor højt indholdet af capsaicin er i nudlerne.

    Eksperterne noterer sig desuden i rapporten, at der på hjemmesiden er billeder af tre "drenge/unge mænd".

    - Ud fra ansigtsudtryk og kropssprog ser det ud til, at to af drengene har ondt i maven eller brændende fornemmelse i mundhulen efter at have spist af nudlerne, står der i rapporten.

    Kan man ikke få lov til at læse den rapport? Det lyder som om, det kunne være en god intro til hvordan man ignorerer den videnskabelige metode, datagrundlag og fakta generelt, og bare skriver hvad man nu lige føler for i dag. Det lyder i hvert fald ikke som et grundlag, hvorpå fødevarestyrelsen bør agere — og da slet ikke med vendinger som "risiko for akutte forgiftninger" og lignende.

    Hvad er det for en "forbruger", der har henvendt sig og hvem er den i familie/venner med fra fødevarestyrelsen?

    De må hellere tilbagekalde nisseøl pga. risiko for akut alkoholforgiftning. Fucking klaphatte...

    Edit: Jeg antager, at det her er billedet, de henviser til i rapporten: https://web.archive.org/web/20231003202700/https://asiatorvet.dk/shop/53-samyang/ Et promo-shot for produktet, der sælger sig selv på at være stærkt.

    Edit 2: Rapporten er her: https://janax.dk/wp-content/uploads/2024/06/Nudler-med-chili-6.-juni-2024.pdf Den er ikke helt så dum, som først antaget, men det er sgu stadig en usaglig affære.

  • Notifications Received in 30 Minutes of Class — LessWrong
  • I get notifications for calls (obviously), SMS messages (of which I receive an average of 1 per month) and IMs from my immediate family. Everything else I check up on when I actually feel like I have the time for it. This has dramatically reduced the number of emails and other things I forget to reply to/act on, because I see them when I want to and when I have the time to actually deal with them; not when some random notification pops up when I'm doing something else, gets half-noticed and swiped away because I'll deal with it later.

  • Chrome: 72 hours to update or delete your browser.
  • The headline is supposedly CISA urging users to either update or delete Chrome — it's not Chrome/Google itself. However, I'm having trouble finding the actual CISA alert. It's not linked in the article as far as I can tell.

  • ChatGPT Answers Programming Questions Incorrectly 52% of the Time: Study
  • Fair enough, and thanks for the offer. I found a demo on YouTube. It does indeed look a lot more reasonable than having an LLM actually write the code.

    I'm one of the people that don't use IntelliSense, so it's probably not for me, but I can definitely see why people find that particular implementation useful. Thanks for catching and correcting my misunderstanding. :)

  • ChatGPT Answers Programming Questions Incorrectly 52% of the Time: Study
  • I'm closing in on 30 years too, started just around '95, and I have yet to see an LLM spit out anything useful that I would actually feel comfortable committing to a project. Usually you end up having to spend as much time—if not more—double-checking and correcting the LLM's output as you would writing the code yourself. (Full disclosure: I haven't tried Copilot, so it's possible that it's different from Bard/Gemini, ChatGPT and what-have-you, but I'd be surprised if it was that different.)

    Here's a good example of how an LLM doesn't really understand code in context and thus finds a "bug" that's literally mitigated in the line before the one where it spots the potential bug: https://daniel.haxx.se/blog/2024/01/02/the-i-in-llm-stands-for-intelligence/ (see "Exhibit B", which links to: https://hackerone.com/reports/2298307, which is the actual HackerOne report).

    LLMs don't understand code. It's literally your "helpful", non-programmer friend—on stereoids—cobbling together bits and pieces from searches on SO, Reddit, DevShed, etc. and hoping the answer will make you impressed with him. Reading the study from TFA (https://dl.acm.org/doi/pdf/10.1145/3613904.3642596, §§5.1-5.2 in particular) only cements this position further for me.

    And that's not even touching upon the other issues (like copyright, licensing, etc.) with LLM-generated code that led to NetBSD simply forbidding it in their commit guidelines: https://mastodon.sdf.org/@netbsd/112446618914747900
