Chirono··on A look under our trunk: what's in our compute
That night image looks very heavily cropped based on the field of view.
Chirono··on A look under our trunk: what's in our compute
They mean no human at the wheel to take over if the hardware dies. If you are driving full speed down the highway and your gpu packs up, you’d better have a backup to bring the vehicle to a safe stop.
Chirono··on Don't trust large context windows
That’s usually not true due to caching. It may be true if you leave a large gap in between, but if you send “make it red” right after, then it’s purely incremental
Chirono··on BusyBeaver(6) Is Quite Large
Exactly. This number is so so much bigger than 10^100000 or however many grains of sand would fit, that dividing by that amount doesn’t really change it, certainly not enough to bring it down closer to 9,999,999sub10
Chirono··on Differential Transformer
The two other changes they mention have been widely adopted, and are included in at least some of the models they benchmark against. It seems they list them for completeness as changes to the original transformer architecture.
Chirono··on Artificial intelligence is losing hype
This is just an artefact of tokenisation though. The model simply isn’t ever shown the letters that make up words, unless they are spelled out explicitly. It sees tokens representing groups of words. This is a little like saying a human isn’t intelligent because they couldn’t answer your question that you asked in an ultrasonic wavelength.

Chirono··on Arthur Whitney releases an open-source subset of K with MIT license
I used to use K professionally inside a hedge fund a few years back. Aside from the terrible user experience (if your code isn’t correct you will often just get ‘error’ or ‘not implemented’ with no further detail), if the performance really was as stellar as claimed, then there wouldn’t need to be a no benchmark clause in the license. It can be fast, if your data is in the right formats, but not crazy fast. And easy to beat if you can run your code on the GPU.
Chirono··on Enhancing Factorio with SAT solvers
For anyone wondering what this does, it looks like it produces optimal configurations for belt balancers given a specified number of input and output belts. Belt balancers evenly distribute items between belts: https://wiki.factorio.com/Balancer_mechanics
Chirono··on Why is machine learning 'hard'? (2016)
In some cases you can directly test hypotheses like that, but more often than not, there isn’t a way to test without just trying.
Chirono··on Depth Anything: Unleashing the Power of Large-Scale Unlabeled Data
Nice paper. I particularly like how they talk through the ideas they tried that didn’t work, and the process they used to land on the final results. A lot of ML papers present the finished result as if it appeared from nowhere without trial and error, perhaps with some ablations in the appendix and I wish more papers followed this one in talking about the dead ends along the way.
Chirono··on Code is run more than read
That’s only true for linearly ordered structures, but isn’t true for partially ordered ones.

For example, set inclusion. Two different sets can be neither greater than not smaller than each other. Sets ordered by inclusion form a partially ordered lattice.

Chirono··on Show HN: A Dalle-3 and GPT4-Vision feedback loop
Interesting! Do you have a link to that research?
Chirono··on Understanding Deep Learning
From reading this book you’d have a very good grasp of the underlying theory, much more than many ML engineers. But you’d be missing out on the practical lessons, all the little tips and intuitions you need to be able to get systems working in practice. I think this just takes time and it’s as much an art as it is a science.
Chirono··on Gaia-1 a 9B parameter generative world model for autonomous driving
Wayve is developing their own autonomous vehicle system, so I think they are their own target audience here.
Chirono··on Getty made an AI generator that only trained on its licensed image
The other angle on ‘Corporate AI’ is when we’ll start to see product placement and adverts inside generated content. Create an image of coffee, and you’ll find Starbucks logos everywhere. Ask an LLM about a topic and see it work in an advert about a particular brand of beer. I’m sure people are working on this already, but I really hope it never happens.
Chirono··on Gaussian Splatting: The next big thing in 3D [video]
It’s entirely static for now. I’m sure we’ll see techniques for dynamics objects eventually though.
Chirono··on AttentionViz: A Global View of Transformer Attention
Link seems to be dead?
Chirono··on Emergent abilities of large language models
What would you propose instead?
Chirono··on Talking About Large Language Models
out of interest, is there anything specific you think humans will always be better at than AI?
Chirono··on Talking About Large Language Models
Of course they’re different. But so what? That’s not exactly proof of anything, unless you’re suggestion biological neurons are the only configuration in the universe capable of thought? Maybe that’s true, but it seems unlikely to me.

The pressure of natural selection can lead to the phenomenon of consciousness. Why not the process of training llms? Perhaps developing the machine equivalent of consciousness helps that particular configuration of weights survive the otherwise destructive process of gradient descent.

Chirono··on Talking About Large Language Models
This paper, and most other places i’ve seen it argued that language models can’t possibly be conscious, sentient, thinking etc, rely heavily on the idea that llms are ‘just’ doing statistical prediction of tokens.

I personally find this utterly unconvincing. For a start, I’m not entirely sure that’s not what I’m doing in typing out this message. My brain is ‘just’ chemistry, so clearly can’t have beliefs or be conscious, right?

But more relevant is the fact that llms like ChatGPT are only pre-trained on pure statistical generation, followed by further tuning through reinforcement learning. So ChatGPT is no longer simply doing pure statistical modelling, though of course the interface of calculating logits for the next token remains the same.

note: i’m not saying i think llms are conscious. I don’t think the question even makes much sense. I am saying all the arguments that i’ve seen for why they aren’t have been very unsatisfying.

Chirono··on The Tesla Semi cab from the practical POV of someone who drives trucks
Yes there are: https://www.volvotrucks.com/en-en/trucks/alternative-fuels/e...
Chirono··on A hundred UK companies sign up for four-day week with no loss of pay
Stretch the timelines out a bit. Say the asteroid is two years off (a fairly typical startup runway). I would much rather know the planning, decisions and execution of the one thing that could save my life were done by well rested and level headed individuals, not stressed out sleep deprived people more prone to missing details and making mistakes.
Chirono··on The global housing market is heading for a brutal downturn
I still find it strange that housing is expected to be an appreciating asset class, rather than a depreciating one that requires continual investment to counteract wear and tear etc. I understand that this is largely by design, but it seems odd to me how much this is accepted as fundamental to properties, rather than something that’s been constructed.
Chirono··on Ask HN: What interesting problems are you working on?
That code is written in a very declarative, functional style. Haskell is a language that forces you to write code like that, so might be a worth a look if your goal is to write ‘pretty’ code.

However, I’d also add that becoming an “elegant” and “useful” programmer are often at odds with each other. It’s very easy to spend so much time trying to make your code pretty with the perfect abstractions that you never actually finish anything.

If your goal is to be useful and productive then learning by writing a lot of code in a lot of different languages, styles and code based might serve you better than focussing on beautiful source code. Though if you can do both, then please do!

Chirono··on Not Your Grandmother's Textbook Exercise
I’d double check your working there because it certainly is true. In your example the standard deviation (2e29) is far bigger than the difference between the median and mean (5e28).
Chirono··on AI generated, command whatever you want. It will generate mind-blowing images
Are there any details on how this works anywhere? It kinda looks like a diffusion model, but using Gaussian blur instead of the Gaussian noise that dall-e etc use.
Chirono··on The Poor ROI of Autonomy (2020)
Yes, the DLR in London has goes overground and has run without drivers since the 80s.
Chirono··on Ask HN: What has been your experience with bigger tech companies in London?
To get an idea of comp for companies in London, levels.fyi is a good starting point. https://www.levels.fyi/Salaries/Software-Engineer/London/ Bottom line is that comp is way under what you would get for the same job in the US, but better than most other engineering jobs in London outside of certain finance roles. The market seems to have been going up a lot in the past couple of years though.

The interview process is pretty much the same as you get in the US. Lots of leetcode and system designs.

Chirono··on Show HN: Symbolica – Try our symbolic code executor in the browser
I think the surprise comes from how long it takes to get the answer, not that it's incorrect.

By comparison, gcc is able to reduce those two implementations to the same thing and prove them equal in a fraction of the time (https://godbolt.org/z/6oMEd8ebY). If it takes Symbolica a minute for the same tiny example, how does it work on real codebases?
