The scale word gets a lot of attention in this. The interpretation that I use is effectively to avoid adding the human priors to your learning process. And if you read the original essay, this is what it talks about is how researchers will try to come up with clever solutions to their specific problem that might get them small gains in the short term while simply enabling these deep learning systems to work efficiently, and for these bigger problems in the long term might be more likely to scale and continue to drive success.

👇 Great work led by Yushun (@ericzhang0410) introducing Adam-mini, a version of Adam that, surprisingly, reduces Adam's memory requirement by 50% (!), without negatively affecting convergence rates. Please read Yushun's thread for details! Quoting @yushun_zzz Finally finished Adam-mini! A "mini" version of Adam that painlessly frees 50% of memory over Adam. Some highlighted features: 1. Adam-mini saves 50% memory over Adam for all modern neural nets. This is done by removing 99.9% Adam's v (but the last 0.1% of v is essential and necessary). 2. Adam-min… Related
Great blogpost by Ruiqi (and other GDM ex-colleagues), clearly explaining the the connection between flow matching and diffusion models. Super happy they took the time to explain this topic, there's confusion on this topic, I think many will find this quite valuable! Quoting @RuiqiGao A common question nowadays: Which is better, diffusion or flow matching? 🤔 Our answer: They’re two sides of the same coin. We wrote a blog post to show how diffusion models and Gaussian flow matching are equivalent. That’s great: It means you can use them interchangeably. Related

A korrent is a belief a person has stated in their own words: one
sentence stating the claim, backed by a quote and a source, kept at
korrents.com .
Under a name here, the quoted block is what they actually said.
The korrent beneath it is the claim those words support, in
korrents' wording — tap it to see the record, its source, and who
else holds it.
Nobody here wrote their own korrents. They are compiled from public
statements, and a person can change their mind, which is recorded too.

About the English under a post
Some people here publish in a language other than English. Where they
do, this site shows a machine translation beneath the post, in
this typeface — the site's own, not theirs.
The post itself is never changed, moved or hidden: what is set in the
serif above is exactly what the person published, and it is what to
quote them on. A translation can be wrong in ways that matter,
especially about tone.
Only the post's own words are translated. A quoted post, a linked
article and a belief on korrents.com
are left in their original language.
