That’s why you log transform income.

I would strongly support this. And given the current state of the Brazilian team, I have no ulterior motives whatsoever. 🤥

Apparently the NeurIPS chairs decided to reopen the camera-ready submission to ensure "that the proceedings reflect the highest scientific quality.” @neuripsconf.bsky.social, is that true?

So the solution to academic misconduct is to give the authors a chance to cover their tracks?
What is wild to me is the defense, BY THE NEURIPS BOARD, that fabricated citations do not mean "the content of the papers themselves [is] necessarily invalidated"

It does. It very much does. What do you think citing other work is for? What do you think writing a paper is for? What do you *think*?
NEW: NeurIPS,one of the world’s top academic AI conferences, accepted research papers with 100+ AI-hallucinated citations, new report claims

I fear my tipping point into madness is "Thus is un-American" posts in response to ICE terrorizing immigrants. I beg you to open Wikipedia (I would say a book but let's start small) and read up on The Trail of Tears, Fugitive Slave Catchers, Japanese internment, Indian Boarding schools & Jim Crow

I complain about the steady increase of entropy in the universe, and the best thing I can do to remedy the situation is absolutely nothing.
I am intrigued by people who complain a lot, but do nothing to improve things. Some people complain about the same things for years. It seems to me that if they would spend that energy into something productive, they would be happier, and the world would be a bit better.

The nerdiest, and thus best, way of getting a bibitex entry from a DOI is by querying it directly via the command

curl -LH "Accept: text/bibliography; style=bibtex" doi.org/10.1016/j.ch...

The second best is just to use @zotero.org for everything.
Just checking, since apparently some are using LLMs to get BibTeX snippets easily.

For Computer Science and ML papers, you know about @dblp.org, right? You know you don't have to use LLMs for that... right?

Remarkable speech in its confession that the “rules-based international order” has been a farse all along.
Canadian PM Carney’s speech at Davos reportedly received a standing ovation.

The speech marked the end of an era.

It will no doubt be looked to as part of the historical record of the end of the transatlantic rules-based international order.

You can read the speech in full here:

Why is Germany trying to build ‘Europe’s strongest conventional army’?
Germans say they want a powerful military and EU nuclear deterrent to replace US hegemony, discomfiting Russia.

This shit has been happening in Latin America and other parts of the world for half a century. Welcome to the club.
This, right here 🎯💯. I’ve been trying to communicate this to people, as a native 🇨🇦, for a year now. Again, the fact that this wasn’t immediately seen as a presidency-ending, beyond-the-pale thing for all 535 Congresspeople, the media, & the public is deeply ugly & shameful for us as a country.

American left? Sounds like a great idea. They should get one.

In the 23 years since, the US has had 12 years of democrats in the white house, 6 of them with full control of Congress, and another 6 with partial control.
In 2003, as part of a massive crackdown on civil liberties, Congress passed a bill creating the Department of Homeland Security, and with it, ICE.

Since then, ICE agents have wreaked havoc on our communities. Enough is enough.
Stop ICE's Attack On Our Communities
An ICE agent shot and killed Renee Nicole Good in Minneapolis. This news is devastating. ICE must immediately withdraw its 2,000 agents from Minnesota and Congress must block any new funding to immigration enforcement.

Both after and before the exchange, neither party, nor the prize, could be attributed with any dignity.

It's a pathetic pantomime, but it's somewhat fitting.

Frankly, a swag bag is a perfectly valued trade for a peace Nobel.

What was wrong with the bayonet?
The murder of Renee Good by ICE is an atrocity that must face justice. Thankfully, accurate and clear video footage shows that this was a cold-blooded murder. This iteration of the print pays homage to that.

This is a sign of ethical collapse. Trump has forced this brave person to debase herself--with gold trimming.

This is a good ansatz as far as the motivation goes, which is based on the minimum description length principle. Unfortunately, this principle is not actually used in the analysis, since no encoding of the data is provided. The paper discloses this fact, but it does undermine the conclusions.
How complex should network models be?

🚨 In our latest paper we quantify (if and) when higher-order interactions are informative versus reducible to pairwise structure without losing functional signal (e.g., diffusion behavior).

This whole thing about having “well regulated armed militias" in case of government overreach turned out to be relevant after all...

Where are they?

(Maybe they would appear if the ICE agents were black? They're already killing white people.)
@statuscoupnews.bsky.social interviewing this woman in Minneapolis right now who said she came out of her home, wearing whatever she could grab to protect herself from ICE agents. You do what you can, with what you got.
