Quanti muoiono in scontri stradali che avvengono da soli, ovvero scontri autonomi senza coinvolgimento di un altro veicolo?

@davidgerard , not sure if you saw this great post about ML models in radiology?

The boosters love to say ‘look how good AI is in medical diagnosis, therefore LLMs are good’. Only, it turns out (from the article):

while models beat humans on benchmarks, the standardized tests designed to measure AI performance, they struggle to replicate this performance in hospital conditions. Most tools can only diagnose abnormalities that are common in training data, and models often don’t work as well outside of their test conditions

It also highlights a problem that’s actually quite general in medicine: we have far more data about unhealthy people than healthy ones. I was talking to a cardiologist almost ten years ago who was very excited about the data things like the Apple Watch could collect. Apparently they know that a lot of people who have heart attack have arrhythmia, but they have no idea if this is a meaningful correlation. Healthy people tend to have their heart monitored for a minute or less on a visit to a doctor every few years. People with known heart problems wear heart monitors that can record a load of things, so you have very good data on their heart rhythms but no baseline to compare it against.

This is also true for radiology. You really want to do anomaly detection: take a few million scans of healthy people, wait a few years to see if any of them have undiagnosed conditions, and then use that dataset to train a model of what a healthy lung (or whatever) looks like. Then feed new scans to the model, have it flag anomalies, and loop in an expert to figure out what kind of anomaly it is and whether it’s important.

But what you have is a load of very examples of things that are wrong, in very specific ways. And these also have artefacts that are specific to individual devices, so it’s easy for a model to learn that people who are scanned with this class of machine have this condition.

And that’s just the start of the issues they discuss.

Looking for some good No Kings protest frog 'HOP' poster art, but concerned that most of the stuff floating around is AI slop?

Greta Thunberg: “They kicked me every time the flag touched my face” https://www.aftonbladet.se/nyheter/a/25LgKq/greta-thunberg-they-kicked-me-every-time-the-flag-touched-my-face

Spoke to a scientist friend today and asked him about Trump’s anti-science campaign & his attacks on universities?

He replied, I don’t think Americans realize that even if we somehow stopped Trump now, he’s already set the USA back at least 20-30 years in scientific research. And given he still has 3 more years, we may not recover from this for half a century or more.

This Economist data is from 6 months ago. You can imagine how much worse it is now.😳

CWA just shared their research into the lives of the US-based data workers responsible for training and maintaining modern “AI” platforms. The findings are, in a word, grim: https://cwa-union.org/ghost-workers-ai-machine

Honey, I invested $100 billion in AI, and all I got was 1 + 2 + 3 = 15

tiktok is heading toward being full maga.

If your business or life is centered on that app, take steps now to change that.

I am happy to help however I can.
