That's why you should prefer LPIPS to PSNR. LPIPS is a learned metric that uses subjective human input. That said, it's limited due to the training set, iirc. So we still use PSNR regularly — it's an easily-understood metric

Curious if the authors are hanging around here and how they feel about the recent Leiden Statement. (Late in the article it’s clear that this is at least partially a publicity effort around a new AI math tool, if I’m reading it correctly.)

Your comment prompted to look into this further, thank you. The funding situation in California is complicated and weird, but yes, CA does spend a lot of money on public education. There are weird relics of the underfunded past, but you can

Well I live in a basic aid district; Bay Area but firmly middle class. We’re just above the cutoff for federally subsidized school lunches iirc, and the schools are chronically short on money. Part of it is declining enrollment, part of it

This is interesting news to me, thank you. I'm curious if the per-pupil spending includes locally raised funds; the reality in California is that the state level funding is poor, and districts that are above some threshold don't

The root cause of the collapse in math education in California is one bad researcher's work, combined with politics. Briefly, a Stanford-affiliated "researcher" named Jo Boaler produced two deeply underpowered studies claimin

This already happens — my district when I was in school, and my son's district now, both have / had "alternative" high schools that kids get transferred to when they're struggling. Kids who are dropping out inevitab

Did people really believe this was a financial behemoth? Or was this just a larger bet on the conglomerate that is Musk’s quasi-meme-stock empire?

In his interview on the Hard Fork podcast, Palo Alto Networks’ CEO described the capability change from Opus to Mythos being more about availability; evidently it runs in a very compute-intensive, always-on mode. Unclear if the base model i

In case anyone is wondering why this is important: the spherical harmonics are frequently most of the data in a Gaussian splat data set — as much as 80% of the data for good quality scenes. The magic of Gaussian splats is their ability to r

It's worth signing up for Levine's free newsletter and listening to the podcast (though there is substantial overlap in the content, it's still fun to hear what you've already read). His take on this, crypto, all things

Because it acquires an asset worth roughly that much, it’s neutral. GME is (probably!) not doing a huge at-the-market offering, they’re creating the shares and immediately giving them to eBay shareholders. In practice the price paid for the

This is not atypical; smaller company “buys” the larger company with debt on the larger company’s books. The blended shareholder mix is mostly the larger company; management comes from the smaller company. The one I was most familiar with w

To be fair, that’s the recommended way to put out an alkali metal fire. At least according to my grandfather who helped write safety regulations for nuclear subs whose reactors were cooled by liquid sodium. Not really something I’d want to

Missed in the previous discussion: methanol is irrelevant. Grain based ferments have essentially zero methanol.(And methanol risk is a function of its concentration relative to ethanol — the treatment for methanol poisoning is… ethanol!) ev

This is called “ghost frame” and already exists in Red cameras and virtual production wall tools like Disguise.

This is a good, succinct unpacking of the metaphysical stakes. Nonetheless I am curious for the world where striking a match results in a shower of seagulls.

The article talks about how they are controlling for the variation across time, and they’re reporting a new signal. So even if everyone was working Saturdays before, everyone is more working Saturdays now. (Edited typos.)

I suspect that the biggest limitation in printing vs. emissive displays is the simple fact that your contrast ratio and color reproduction is severely limited in printing, because the dye is modifying ambient illumination. This affects brig

That’s precisely what LIGO measures, the gravitational waves from black hole mergers (or neutron star mergers, etc).

Do you know that there is an actual voxel representation that exists before the self-driving AI? I was under the impression (from conversations with engineers who might know, admittedly) that there was not an explicit 3D representation

This is actually even more puzzling than it seems, because the green part of the spectrum is the most energetic. I've read elsewhere that photosynthesis is partially limited by dealing with free radicals, and at peak light flux, many p

Genuine questions for AI engineers, or self driving car people: is the Tesla approach of only using cameras inherently flawed? I've read that the AI is directly hooked up to the cameras, with no explicit intermediate 3D representation.

Purely intuitively, it seems like there should be a connection between the two (computation and intelligence). But I have not formally studied any relevant fields, I would be interested to hear thoughts from those who have.

Wait... not having spelling errors is now a mark of AI? Am I the only person who proofreads emails anymore?

Agreed, I'm torn between my pedantry for adhering to style guides and being pilloried for seeming like an AI. There's no safe ground anymore. (Though I used to use the em dash with spaces on either side — like this — and only rece
