I second that. None of that stuff is supposed to work as good as it does.
The more I learn about machine learning in general and transformers in particular — and while I have a long way to go, I've learned a LOT — the more I believe that none of it really ought to work. Slamming a set of matrices with training data and demanding with calculus that they figure it out…

It's completely impossible to search for anything that somebody sells as a product, and I'm losing my mind. I can't find simple basic facts about anything anymore.

The z image model is deeply impressive, the scary thing is theres no guardrails on this thing *at all*. Gemini's watermarking is now utterly pointless and now maybe people will learn DRM isnt ever the answer to the problems we face.

So it appears that a time series model that is very good at prediction of demand will make best use of the lag variables and therefore will almost be unusable to estimate real price elasticity. I didn’t know that and now feel somewhat stupid.

The headline, the main takeaway from a European viewpoint is this:
The transatlantic relationship as we know it is over. Yes, we kinda knew this. But this is now official US White House policy. Not a sppech, not a statement. The West as it used to be no longer exists.

I really think things would already improve if we brought back Nixon.
If we’re bringing back things from the 70’s, could we bring back Republicans who put country over party? You know, like the ones who were going to give Nixon the boot before he resigned?

Australia is nature‘s way of saying „I can make that in very poisonous“.
The toxic crab (Lophozozymus incisus), a rare and very beautiful species found in warm waters the world over, including off the coast of Australia.
Toxic crabs can be incredibly dangerous, containing toxins that are similar to those of the pufferfish, called tetrodotoxin and saxitoxin.
