“In the study, AI overestimated the age of smiling faces even more than human observers and showed a sharper decrease in accuracy for faces of older adults compared to faces of younger age groups, for smiling compared to neutral faces, and for female compared to male faces. “These results suggest that estimates of age from faces are largely driven by visual cues, rather than high-level preconceptions,” said lead author Tzvi Ganel, Ben-Gurion, department of cognitive and brain sciences. “The pattern of errors and biases we observed could provide some insights for the design of more effective AI technology for age estimation from faces.

“AI tended to exaggerate the aging effect of smiling for the faces of young adults, incorrectly estimating their age by as much as two and a half years. Interestingly, whereas in human observers, the aging effect of smiling is missing for middle-aged adult female faces, it was present in the AI systems,” said Carmel Sofer, Ben-Gurion, department of cognitive and brain sciences.”

> Voters have shown they do not want change, so there will be none

Voters are not the only source of change -- change is happening because it's cheaper.

That's why the USA is closing fossil fuel power plants twice as fast as it's building them (7.5GW added vs. 16GW retired in 2023).

That's why Texas went from 6% wind+solar in 2012 to 17% in 2017 to 31% in 2022.

And that's also why the International Energy Agency projects carbon emissions will fall 15-20% by 2030.

Is that a morally satisfying reason for change to occur? No, not really -- it feels weird to have the right thing happen for the wrong reason. Climate change is important enough that we don't really get to be choosy about why the needed change is happening, only that the needed change is happening.

And, make no mistake, as the above data shows change is indeed happening. It may not be the kind of sweeping environmental awakening one might have hoped for, but it replaced coal and gas with wind+solar+storage, so for now that'll have to do.

And the Mediterranean diet is associated with increased cardiovascular health. Things like lentils and soy are associated with longevity and not nutritionally the same as refined wheat and sugar.

Amen, sir.

> The math IS the explanationYou're right and that's a great way of putting it, but there should be a way to use appropriate analogies to convey those concepts without using equations. It would be really cool if we then formalized said analogies into a set of domain specific terminology being used when talking about anything in the realm of quantum. For example, imagine how hard it was to communicate to your peers about vector fields before the concept of a vector was invented; having a word to easily encapsulate the mathematical meaning makes it easy for us to have discussions about velocity and magnets without using any actual number or formulas.

Sorry, don't mind my rant, I just feel like there needs to be a better way of teaching and communicating things in this field.

I got my 87yo, republican Father to admit universal healthcare would be a good thing because I framed it as an investment in the health of the population, which would be more productive as a result, and make America's economy stronger.
