Could you provide a citation or reputable news article for this? I am not seeing anything claiming this yet elsewhere online.

Or, if you prefer, you can think of it as a generalization of the Bayesian information aggregation and Aumannian agreement literature!

This characterization looks a swap regret guarantee that you can think of as a multiparty generalization of our swap regret formulation of multicalibration for regression problems from arxiv.org/abs/2301.13767
Multicalibration as Boosting for Regression
We study the connection between multicalibration and boosting for squared error regression. First we prove a useful characterization of multicalibration in terms of a ``swap regret'' like condition on...

I'll defer to Aaron's excellent summary thread for the details but tldr, when is collaboration useful if you can only send your prediction and not features? Here we give a precise characterization for boosting in this collaborative setting.

Like, the text of this isn't about illegal immigrants at all by my reading, it is about *any* immigrants except green card holders maybe? It feels very disingenuous to report on this as if it isn't.

Extending this logic from theoretical physics to theoretical CS and math, you could probably make the argument that any smart person who chooses to do obscure math theory is guilty of this kind of brain drain. And that seems at least somewhat silly.

That's a lot different than having huge grants and for social science projects w junk statistical analysis. Like maybe the intellectual clout is still there for string theory and but the funding isn't. So worst case is you get brain drain from other subareas that would benefit from it.

I think there are also big differences in funding between string theory and your social science examples. I haven't found a nice presentation of eg grants in physics broken down by subject, but anecdotally it is very hard for grad students to get into string theory bc funding is vanishing.

Including to the emails to my letter writers? I'm not even sure if my letter writers all know my legal name.

I know the real world is filled with ambiguity and that there is value in consistency, which relying on precedent aids. But I struggle with the logic of the justification of decision making being consistency itself. I'm sure I'm missing something, so hmu if you have any favorite resources.

Maybe? I'm not sure how this would work w precedent in copyright law. Eg even if something becomes public domain, I believe there is currently nothing that requires the owner to make it actually accessible. For instance, if I own an old painting, I don't need to show it publicly.

I shouldn't have been horrified in retrospect; I've seen this trick used in Serious Eats' cheese sauces as well.

the idea of using corn starch gives me the heebie jeebies but I am...intrigued by their argument.

How do we combat code obsolescence? In general there aren't good incentives in most companies for maintaining code vs producing new products or services, even though you'd think maintaining existing products would be sort of incentive compatible with a companies goals bc it improves consumer trust.

But fundamentally I don't know how to prevent this kind of problem. What are reasonable regulatory mechanisms to prevent "predatory" subscriptionification? On some level these things are branded as a benefit to the consumer, so idk where the line is.

It's possible it was a resolvable problem, but my roof fell in above the printer a week later so I took the L and just print everything in office now that we're back to in-person.
