The title reads a lot like the lab logs you'd find in a horror game.

But for the paper itself, it seems they're using genetic optimization over predefined keywords. Wonder what would happen if they did gradient descent on the latent space directly. Is brain stimulation just not a good domain for GD?

This is very similar to last week with that mind reading startup thing. Please read the paper before commenting. This is a tool to help researchers in figuring out what different parts of the brain are actually for with less experimenter bias contamination of “well we think maybe it’s about this so let’s show it video of x to see”. The essence runs on having someone sit in a scanner for a couple hours watching all so…

>Expose brain to something, record it somehow, see if brains reaction in the recording helps you understand more about who we are and what cognition is.

It also helps companies like Moonbug Entertainment (Candle Media) understand how to build better Distractatrons.

    It’s a small TV screen, placed a few feet from the larger one, that plays a continuous loop of banal, real-world scenes — a guy pouring a cup of coffee, someone getting a haircut — each lasting about 20 seconds. Whenever a youngster looks away from the Moonbug show to glimpse the Distractatron, a note is jotted down.

    “It’s not mega-interesting, what’s on the Distractatron,” said Maurice Wheeler, who runs the research group. “But if they aren’t fully focused, they might go, ‘Oh, what’s that?’ and kind of drift over. We can see what they’re looking at and the exact moment when they got distracted.”

Apart from ethically bad and evil use cases of this application, can we use it to massage the parts of brain like we do it to our bones and muscles with the help of physiotherapists? reason I am asking it could be some relief to our brains after tedious working day, especially after heavy AI usage

what the brain needs is Default Mode Network, not more stimuli

I know a technology like that was used ~20 years ago for ADHD. EEG feedback, as soon as the kid looks away or zones out, the movie stops playing.

As others on Telegram have said: automated search for visual superstimuli likely leads to bad outcomes. https://en.wikipedia.org/wiki/Supernormal_stimulus https://en.wikipedia.org/wiki/BLIT_(short_story) Also: one of the V3A animations reminds me loosely of things I saw when I was a kid, at night, shortly before I slept (though my experience then was more circular).

Earlier quoted context omitted.

This does indeed seem comically evil. While surely this may provide somewhat interesting insights in how our brain processes things, this seems squarely past the "should" part of "you scientists were so obsessed with whether you could you failed to consider whether you should"

> This does indeed seem comically evil. And I have yet to see a single paper like this where a researcher bails out and publicly says they refuse to work on such projects. Not one. The most benign interpretation of this observation is that science is filled with spineless opportunists who don’t care who they hurt with what they create. A slightly less benign interpretation might be that many of these people are doing…

When skip level bosses on my last job wanted to do boneheaded things in automotive design they usually had to keep asking different engineers until they got a yay.

When it is pushed from the top it is hard to stop at ground level.

My brain never liked vertical video, shortform content and AI slop. Is my brain different or am I just a grumpy millenial hipster?

My current theory is that these are similar to cigarettes. Nobody likes the first draft, it burns your lungs, your entire body wants to reject it. But the nicotine stimulates just the right receptors so that if you keep at it for just long enough, you'll be hooked and start disregarding the terrible taste, smell, tar in your lungs, and yellowing of your teeth. All of this to say, if you subjected yourself to just eno…

I have the opposite theory. I burned my self out on cheap and bad image gen meme sites like 15 years ago until the point I hated memes.

Prior exposure to worse feeds gives like an analytical look on the vids rather than emotional. I am fast scanning for the joke. Or something.

That's fascinating. I wish the demo videos were longer.

Am I the only one who is avoiding even clicking the link just in case?

It is like screen saver moving patterns or corridors with a strange field of view zooming effect.

Nothing special compared to purpose made screen savers.
