Language models pack billions of concepts into 12k dimensions

In a recent 3Blue1Brown video series on transformer models, Grant Sanderson posed a fascinating question: How can a relatively modest embedding space of 12,288 dimensions (GPT-3) accommodate millions of distinct real-world concepts? The answer lies at the intersection of high-dimensional geometry and a remarkable mathematical result known as the Johnson-Lindenstrauss lemma.

Decades-Old Waste Barrels Are Creating Toxic Dead Zones off LA’s Coast

gizmodo.com Ellyn Lapointe 2025-10-02 13:15:47

Until 1972, the Pacific waters of Southern California served as a dumping ground for hazardous and industrial wastes. More than 50 years later, corroded metal barrels still litter the seafloor off the coast of Los Angeles, and scientists are only beginning to understand the consequences of casually tossing them into the ocean. Images of the barrels first surfaced in 2020, with some of them encircled by mysterious white halos on the seafloor. Experts initially linked the barrels to DDT—a toxic p

How many dimensions is this?

news.ycombinator.com Unknown 2025-10-02 15:25:21

In the past couple of weeks, I’ve been posting about seemingly simple mathematical problems that defy intuition, and where the answers we find on the internet turn out to be shallow or hard to parse. For a taste, you might enjoy the articles on Gödel’s beavers or on infinite decimals. Today, let’s continue by asking a simple question: how many dimensions does a line have? A trained mathematician might blurt out an answer involving vector spaces or open set coverings, but there’s no fun in that.

The maths you need to start understanding LLMs

news.ycombinator.com Unknown 2025-10-02 18:10:47

The maths you need to start understanding LLMs Actually coming up with ideas like GPT-based LLMs and doing serious AI research requires serious maths. But the good news is that if you just want to understand how they work, while it does require some maths, if you studied it at high-school at any time since the 1960s, you did all of the groundwork then: vectors, matrices, and so on. One thing to note -- what I'm covering here is what you need to know to understand inference -- that is, using an

A Random Walk in 10 Dimensions (2021)

news.ycombinator.com Unknown 2025-10-12 04:20:34

Physics in high dimensions is becoming the norm in modern dynamics. It is not only that string theory operates in ten dimensions (plus one for time), but virtually every complex dynamical system is described and analyzed within state spaces of high dimensionality. Population dynamics, for instance, may describe hundreds or thousands of different species, each of whose time-varying populations define a separate axis in a high-dimensional space. Coupled mechanical systems likewise may have hundred

Google is changing how Extra Dim works on the Pixel 10, and it’s so much better

Joe Maring / Android Authority TL;DR The new Pixel 10 series integrates the “Extra Dim” feature directly into the main brightness slider, making it easier to access. This removes the need for a separate toggle, as Extra Dim now automatically activates when the brightness slider is at its minimum. While the feature was tested on older Pixels, it is currently exclusive to the Pixel 10, though it may come to other devices later. Google’s new Pixel 10 series introduces some surprise display upgr

Given the explosive finale of the first episode, we’re in for a lot of explanations from our silver-helmeted would-be hero.

Huge Parts of the North Sea Seabed Are Upside Down, New Study Reveals

gizmodo.com Margherita Bassi 2025-10-28 04:25:03

In the world of stratigraphy, or rock layers, superficial sediments are usually younger than the deeper ones they settle upon. The North Sea, however, has revealed giant mounds of sand that defy this geological principle on a scale scientists have never seen before. Researchers from Norway and the UK have identified hundreds of sand bodies under the North Sea that seem to have sunk deeper into the ocean’s crust, swapping places with older layers, which floated to the top of the sand structures.

Writing Speed-of-Light Flash Attention for 5090 in CUDA C++

In this post, I will walkthrough how I learned to implement Flash Attention for 5090 in CUDA C++. The main objective is to learn writing attention in CUDA C++, since many features are not available in Triton, such as MXFP8 / NVFP4 MMA for sm120. I also feel this is a natural next step after learning about matmul kernels. Lastly, there are many excellent blogposts on writing fast matmul kernels, but there is none for attention.

With Superman in the books, the time has finally come to see how DC Studios’ rebooted universe will continue with the second season of James Gunn’s John Cena-led TV series, Peacemaker. Even before the show’s release, Peacemaker existed in a unique transitional phase between the old and new DC Universes, leading fans to wonder which elements would carry over and which would be left behind. The answer to that, as gleaned from trailers and the occasional Gunn interview about its premiere being not

Low-Temp 2D Semiconductors: A Chipmaking Shift

news.ycombinator.com Samuel K. Moore 2025-12-19 14:52:33

Chipmaking giants like Intel, Samsung, and TSMC see a future where key parts of silicon transistors are replaced with semiconductors that are only a few atoms thick. Although they’ve reported progress toward that goal, that future is generally thought to be more than a decade away. Now, a startup spun out of MIT thinks it has cracked the code for making commercial-scale 2D semiconductors and expects chipmakers to have integrated them in advanced chips in half that time.

Astronomers Spot Companion Star in Orbit Around Iconic Star Betelgeuse, Confirming Suspicions

In 2024, astronomers surmised that Betelgeuse might have a stellar “buddy.” If this hypothetical companion existed, it would help answer some questions about the red supergiant’s strange glowing patterns. As it turns out, these suspicions were correct. After numerous false signals and empty search results, astronomers with NASA’s Ames Research Center have confirmed that Betelgeuse does, in fact, have a tiny buddy star.

Time Is Three-Dimensional and Space Is Just a Side Effect, Scientist Says

A fringe new theory suggests that time is the fundamental structure of the physical universe, and space is merely a byproduct. According to Gunther Kletetschka, a geologist — not a physicist, you'll note, but more on that later — from the University of Alaska Fairbanks, time is three-dimensional and the dimensions of space are an emergent property of it, a press release from the university explains.
