The art of fact-checking

[ny_quant]

CLAIM: Greta Thunberg recently deleted a tweet she posted in 2018 in which she said that the world will end in 2023.

AP’S ASSESSMENT: Missing context. While Thunberg did delete a 2018 tweet about the urgency of addressing climate change, she did not say the world would end in 2023. Her tweet included a quote from an article that said an influential scientist warned climate change “will wipe out all humanity” unless fossil fuel use was ended “over the next five years.” Further complicating the issue, that article incorrectly summarized the scientist’s speech. He never made such comments.

...Thunberg never said the world was set to end in 2023. The young activist was quoting an article that was paraphrasing a speech by a Harvard University professor of atmospheric chemistry. The scientist said the world had limited time to act to reverse the disappearance of floating ice volume in the Arctic or there would be drastic consequences, not that the world would end in five years.

The article Thunberg was quoting has since been deleted, but it was published by the site Grit Post in February 2018 with the headline: “Top Climate Scientist: Humans Will Go Extinct if We Don’t Fix Climate Change by 2023,” according to an archived version of the web page. The first line of the story stated: “A top climate scientist is warning that climate change will wipe out all of humanity unless we stop using fossil fuels over the next five years.”

Forbes quoted Anderson as saying: “The chance that there will be any permanent ice left in the Arctic after 2022 is essentially zero.”

> I am reasonably confident now that we understand fully connected networks. They also have a form of attention, in fact (Expected Gradient Outer Product, essentially, supervised PCA).

Are you publishing something about this form of attention?

Спасибо, очень любопытно.

Btw, it also explains grokking. I remember you asked me a couple of years ago about it, but I don't think my answer was correct.

А, да, все основные загадки того, почему и как происходит Grokking, решил Neel Nanda в августе. Замечательная работа, с подробностями и деталями.

Я сделал небольшие заметки на эту тему, и в этих заметках есть ссылки на подробности:

Thanks, interesting work. From a quick look, I think the main idea is right. However the general mechanism was not clarified. EGOP makes clear what feature learning means in general.
