My process control theory textbook has a chapter on neural networks and a lot of the language in control theory has an AI like tinge to it. I think this AI language is native to control theory so it might not be as overblown as it first sounds.
I mean yes, that's what reinforcement learning is.
I always thought my software PID controller with 512kb main memory is quite smart. Pure AI in my opinion.

For anyone wondering (like me) what COP is in this context, it’s Coefficient of Performance: https://en.m.wikipedia.org/wiki/Coefficient_of_performance
and COP 15 is measure at 1.3'C temperature difference towards outside of fridge, so if it is 80f in your home then good luck to your lettuce.
Why, what would happen to my lettuce if I set the thermostat near the cooling element to e.g. 3°C and have the cabbage be somewhere between that and 4.3°C?

#215But why? Cooling has been a solved problem for literally over a century. No Peltier cooler will ever even come close to normal refrigerant-based coolers in efficiency, both in cost and power consumed.
Are you implying that "normal refrigerant-based coolers" are somehow always the most appropriate solution for any cooling task?
Not the poster but yes. Compressors use phase change which is fundamentally better way of transferring heat. Solids like peltiers will always leak more heat than liquid to gas phase change. Peltiers cannot get the same efficiency because of physics.

#216AI hi guys, pretty great AI article about this AI Peltier AI cooling AI tech.
Really looking AI forward for another AI Samsung new AI devices.
Best regards,
AI
Ps.: AI

#218This article uses the term AI 5 times to talk about basic microcontroller sensor readings.
Just a few years ago, the buzzwords were "germicidal", "immunity boosting", "anti-bacterial", etc. for every damn thing, especially in India, where marketing can get away with bizarre claims.
Is there anything that is proved to be "immunity boosting" apart from vaccines?
Well, and germs of course. Germs will cause an immune response, but that's probably not the kind of "boost" you are interested in.
As for AI, I guess it is sufficiently vague and also not a medical claim, so you can put it everywhere. But because it is just as vague for consumers, is it even worth something for marketing?

A thermostat is a cybernetic device.
And Cornelis Drebbel invented the first thermostat and the first chemical air conditioning system in the early 1600s. Cybernetic alchemist.
