Put another way, EEG moves top-10 retrieval out of 512 candidate words from 20.3% -> 27.7%. Hardly "open-vocabulary word decoding" The paper is also missing a critical control of feeding Llama the preceding ground-truth text an

That is sobering for sure, I wonder what the theoretical bounds are on what is possible if known. Would be such a dream to use a Frontier LLM one day with homomorphic encryption, but this sounds wildly implausible based on where things are

A key challenge with Alzheimer’s is there is no good mouse model for the disease. While some approximate the phenotype, it’s not clear that the disease model as commonly studied in mice matches well with mechanisms of the human disease. The

Beautifully written and worth the read. And the screensaver nerd snipe is epic.

As a neuroscientist, my biggest disagreement with the piece is the author’s argument for compositionality over emergence. The former makes me think of Prolog and lisp, while the later is a much better description for a brain. I think ermerg

This is a well known phenomenon. It accounts for example in the flash perceived when someone inadvertently looks at an infrared class 5 laser and is blinded

This is fun, and the modeling is cool for sure, but it's well known that ultrasound can be used with surgical precision in the human brain. Focused ultrasound is already used for non-invasive neuromodulation. Raag Airan's lab at S

I know the exercise was to p-hack, but instead I decided to one-shot my attempt at the most reasonable model from first principals: - given that we are looking at a national scale, use only national politicians - use the components from Mac

Any references for 99.9% density with SLM copper? My understanding is that pure copper SLM printing is less frequently done as doesn’t work well with the infrared lasers on most machines, requires high heat & speed, and has more porosit

by tbenst 2y ago
The high thermal conductivity of copper makes it difficult to maintain needed temperatures during SLM. Also, copper is prone to oxidation at high temperatures, further complicating (thermal based) laser melting 3D printing techniques. It’s

Fabric8Labs can print 100% density, whereas Desktop Metal is highly porous. Also Fabric8Labs can directly print pure copper, which has historically been very difficult. The process is also more energy efficient and better suited for small c

x1798DE captured my intent well. For example, tonal languages like Mandarin or Cantonese may be more difficult to decode if vocal cords aren’t vibrating, and languages with more phonemes that have both a voiced and unvoiced version might be

This is a super cool device. Note that the decoding is highly limited: they decode into one of five different sentences. This is easier than five words for example as there is more information to distinguish. Unfortunately the media is blow

Very interesting but hard to interpret until the performance numbers / benchmarks are available. I can already fine-tune a 70B language model at home using CPU + RAM, but it would be so slow as to be almost totally impractical (~20x sl

It’s more about the difference in magnitude of the lenses. This also gives you depth information when combined.

Not sure he can claim the phrase. On cursory glance, can find the phrase in multiple books prior to the publication of the cartoon, using the same phrase. Seems it was already in the vernacular. 1986: "How about the afternoon?" &q

Thanks for the response! So does vscode.dev, but it doesn’t support “Remote - SSH.” Could you confirm if this specific extension is functional? To expand, for Remote - SSH to fully function it must read a ~/.ssh/config file as wel

The web version you linked does not support the remote SSH extension, which is critical for many folks workflows. I can’t do any work without that extension. I’m curious if the android version supports this extension?

I agree! My PhD thesis is on this topic [1]. We’ve also done a very limited pilot test on a patient with ALS, with above random chance. Actual results may vary heavily on individual disease progression—the more motor recruitment that’s inta

Thanks! That is interesting and well reasoned. If one wants to change neural computation via a global oscillator, it would seem that a flashing light, auditory tone, or tactile vibration might be a more potent alternative. These stimuli ind

Cadaver studies have shown that this is almost certainly placebo. Not enough current actually reaches the brain: https://buzsakilab.com/wp/wp-content/uploads/2017/07/Underwo...

We are massively far away from modeling the human brain. First of all, no one can agree what level is necessary to model the brain, and that varies tremendously by scientific question. Personally, my lower limit would be something like the
