benob··on Intel Announces Inference-Optimized Xe3P Graphics Card with 160GB VRAM
Is there anything preventing them from using heterogeneous memory chips, like 1/4 GDDR7 and 3/4 LPDDR? It could enable new MEO-like architectures with finer-grained performance tuning for long contexts.
benob··on A small number of samples can poison LLMs of any size
This work is a good argument against memorization of information seen less than 250 times during training.
benob··on Bit is all we need: binary normalized neural networks
I wonder if one could store only the binary representation at training and sample a floating point representation (both weights and gradient) during backprop.
benob··on Markov chains are the original language models
There was a time when people would estimate n-gram probabilities with feed-forward neural networks [1,2]. We just improved that with the (multilayer) attention mechanism which allows for better factoring over individual tokens. It also allowed for much larger n.

benob··on Markov chains are the original language models
Like it or not, LLMs are effectively high-order Markov chains
benob··on Sampling and structured outputs in LLMs
These techniques are limited to structures that can be checked with bounded history or bounded memory (that can be checked with a grammar or FSA). What about more complex structures that don't factor easily?
benob··on LLM-Deflate: Extracting LLMs into Datasets
My understanding was that the Alpaca data was a distillation from text-davinci-003
benob··on Show HN: The text disappears when you screenshot it
a good benchmark for video understanding in IA
benob··on IBM Technology Atlas
It's funny because automation is the only thing you can expect from AI
benob··on YouTube is a mysterious monopoly
> YouTube views seem to have fallen off a cliff recently

So they started discounting AI data collection bots?

benob··on The Bitter Lesson Is Misunderstood
Stop thinking about text being the data. There are so many other sources, even some that you can generate.

benob··on WebLibre: The Privacy-Focused Browser
Even if it's not on topic, that post is quite interesting.
benob··on Carbon Language: An experimental successor to C++
How is it different from mere syntactic sugar over the same programming concepts? What does it bring that C++ cannot do?

Isn't it just a way of controlling the language vs using normative bodies?

benob··on Algorithms for Modern Processor Architectures
Are there efforts to include the neccessary context in compilers to autovectorize?
benob··on How OpenElections uses LLMs
I wonder how difficult it would be to bias a model so that it subtly corrupts election results when performing OCR.
benob··on Andrej Karpathy: Software in the era of AI [video]
You can generate 1.0 programs with 3.0 programs. But can you generate 2.0 programs the same way?
benob··on Cray versus Raspberry Pi
Cray1 should be compared to nowadays raspberry pi pico 2 / rp2350 which has similar specs (using external ram).
benob··on Agentic Coding Recommendations
> This is not an advertisment for Claude Code. It's just the agent I use at the moment. What else is there? Alternatives that are similar in their user experiences are OpenCode, goose, Codex and many others. There is also Devin and Cursor's background agents but they work a bit different in that they run in the cloud.

What do you recommand to get a Claude-code-like experience in the open-source + local llm ecosystem?

benob··on Chatterbox TTS
Watermarking is easily disabled in the code. I a wondering when they will release model weights with embedded watermarking.
benob··on Chatbots are replacing Google's search, devastating traffic for some publishers
The gemini web (smolweb) has no effective search engine, and therefore links also play a crutial role in content discovery...
benob··on Launch HN: Vassar Robotics (YC X25) – $219 robot arm that learns new skills
I am seeing different prices everywhere: - $199 https://shop.vassarrobotics.com/ - $219 https://shop.vassarrobotics.com/products/navrim-robot-that-l... - $599 https://www.youtube.com/watch?v=TbDTCwzFeIU

Which one is the actual price?

benob··on A proposal to restrict sites from accessing a users’ local network
Isn't it time for disallowing browsers to connect to anything outside same origin pages except for actual navigation?

Servers can do all the hard work of gathering content from here and there.

benob··on Air Lab – A portable and open air quality measuring device
It looks pretty and featureful, but I'd love a cheaper version, maybe without a display.
benob··on Apple Notes Will Gain Markdown Export at WWDC, and, I Have Thoughts
I wonder how to import markdown into Notes
benob··on Gemini Diffusion
I guess autoregressive llms can be finetuned (or continual-pretrained) to do inference using diffusion. We've seen a recent paper (which I don't remember) training from scratch, but it seems overkill. Do Google say how they did it?

Also, does diffusion have the potential to increase speed of cpu-only inference?

benob··on Have I Been Pwned 2.0
Ok, one of my email addresses is in a bunch of leaks. What is interesting is that most services on this list I have never used. How did they get my email in the first place? What is the accuracy of that whole business?
benob··on LegoGPT: Generating Physically Stable and Buildable Lego
It looks like it is an extension of 3d model generation techniques.
benob··on Design and evaluation of a parrot-to-parrot video-calling system (2023)
I wonder whether they used a mirror or simple recordings as baseline
benob··on A Tektronix TDS 684B Oscilloscope Uses CCD Analog Memory
> If you ever remove the interconnection PCB, make sure to put it back with the same orientation. It will fit just fine when rotated 180 degrees but the scope won’t work anymore!

I remember pulling a 486 out of its socket in the 1990s and putting it back with the wrong orientation. There was a poc and a bit of smoke. Something on the mainboard had burnt and it wasn't working anymore.

I used smell to locate the fault, a big trace on the PCB, which I soldered back and magic, it all worked again...

benob··on Matrix-vector multiplication implemented in off-the-shelf DRAM for Low-Bit LLMs
I think you are mixing things. Quaternions are in the same category as complex numbers. They can be represented as matrices, and there are probably nice uses of matrices where the element is a quaternion (such as QDNNs) instead of a real number. My experience is that in massive architectures such as LLMs, simpler forms are more successful unless there is a true benefit to representing things with more elaborate types of scalars (such as in physics, or 3d graphics).
