PainChek is one of these behavioral models, and it acts like a cameraโ€‘based thermometer, but for pain: A care worker opens the app and holds a phone 30โ€ฏcentimeters from a personโ€™s face. For three seconds, a neural network looks for nine particular microscopic movementsโ€”upperโ€‘lip raise, brow pinch, cheek tension, and so onโ€”that research has linked most strongly to pain. Then the screen flashes a score ofโ€ฏ0 toโ€ฏ42. โ€œThereโ€™s a catalogue of โ€˜actionโ€‘unit codesโ€™โ€”facial expressions common to all humans. Nine of those are associated with pain,โ€ explains Kreshnikโ€ฏHoti, a senior research scientist with PainChek and a co-inventor of the device. This system is built directly on the foundation of FACS. After the scan, the app walks the user through a yesโ€‘orโ€‘no checklist of other signs, like groaning, โ€œguarding,โ€ and sleep disruption, and stores the result on a cloud dashboard that can show trends.

2021, MSFT claimed a Teams app could read emotional affect & I's like "holy shit this will fuck over so many Black & autistic & otherwise neurodivergent & women & non-binary ppl & ppl w/ chronic pain & โ€ฆ like Everybody at any of those intersections."

This PainChek thing is that, but a doctors' tool

I don't know, even if public officials signing NDAs is normal, it shouldn't be. Really suspicious behavior.

I also note a lot(*) of data center plans are being done in secret with NDAs being signed by our public officials. Seems like if they're signing NDAs about just planning a data center, maybe they should reconsider itโ€ฆ Or reconsider their jobs.

It's "funny," but the "guessing they don't have a lot of data centers" part I anticipated as being a positive there. But ya, the outsourcing. Ugh.

AI doesn't know 'no' โ€“ and that's a huge problem for medical bots Many AI models fail to recognise negation words such as โ€œnoโ€ and โ€œnotโ€, which means they canโ€™t easily distinguish between medical images labelled as showing a disease and images labelled as not showin...

As an example: AI doesn't understand "no." Because the statements "no ketchup on my burger" and "ketchup on my burger" are almost identical to a machine that does not and cannot actually reason. It's only a 2 letter difference.
