- cassianoleal 3y agoThanks, that was it!
- volleygman180 3y agoThis is loading and endless loop of Captchas for me. Anyone else have this issue?
- makeworld 3y agoYes.
- dontrustme 3y agoa pity that the audio wasn't available to listen to as a link in the article. I want to hear the brain music

- awb 3y agoQuite the atmospheric reverberation. It would be interesting if they picked a hummable tune like Peter Cottontail.
- pohl 3y agoFollow the link to the paper itself that titzer put in their comment. Towards the bottom, right above the Acknowledgements section, there's several WAV files with descriptions of each one.
- cassianoleal 3y ago> The researchers chose “Another Brick in the Wall, Part 1” because they are fans of Pink Floyd Missed an opportunity to use Brain Damage instead.
- genter 3y agoWhile admittedly a popular song, I'd argue it's not the epitome of Pink Floyd. I'd like to see them do this experiment with Brain Damage/Eclipse, climax of Echoes, or Celestial Voices.
- loudmax 3y agoKind of surprising they didn't go with "Another Brick in the Wall, Part 2" instead. Part 1 is very low key and doesn't feature much of a recognizable melody. Musically, it doesn't really stand on its own, it only works as part of The Wall as a concept album. Part 2 has a recognizable melody and it includes the iconic chorus "We don't need no education". If you've grown up in western culture, you've probably been exposed to Part 2 through cultural osmosis even if you're not a fan of Pink Floyd or classic rock.

- titzer 3y agoVery interesting research that is 100% oversold in the popular media. Look at the original paper and listen to the reconstructed audio samples (at the end): https://journals.plos.org/plosbiology/article?id=10.1371/journal.pbio.3002176 https://journals.plos.org/plosbiology/article?id=10.1371/jou... Can you identify which song has been reconstructed? I could not. The basis for song "reconstruction" claims is the song-excerpt identification analysis (e.g. Fig 4) that divides the song into 38 5-second clips and then ranks how closely each identified excerpt is to the expected excerpt--effectively, how well does the reconstruction match 38 excerpts to 38 expected excerpts. This is not reconstructing the song, just matching puzzle parts. A nice piece of neural science, completely misrepresented in the media.
- chewmieser 3y agoI actually did not think it was that bad... It's pretty recognizable on the larger probe count & sample sizes. Pretty cool stuff even if it's early.
- pohl 3y agoI could. It's pretty obvious in journal.pbio.3002176.s007.wav
- wnkrshm 3y agoIsn't this the same issue as with the neuro-visual reconstruction techniques matching on a small collection of samples?
- bondarchuk 3y ago> The basis for song "reconstruction" claims [in the popular media] is the song-excerpt identification analysis Not correct for the Dutch state news, at least. They make the same "reconstruction" claims while showing the audio fragments that don't use any input data (for 1 and 29 patients), while mentioning that it's not very accurate but at any rate still recognizable. https://nos.nl/artikel/2486771-computer-herkent-pink-floyd-nummer-uit-brein-luisteraars https://nos.nl/artikel/2486771-computer-herkent-pink-floyd-n... Based on earlier neural decoding news items I was also expecting something completely overblown, but in this case I think the reporting is quite legit, and you might just be having a knee-jerk contrarian reaction.
- dav_Oz 3y ago>Algorithms already can construct pretty accurate models of a person’s preferences based on physical activities, including typing search terms or tapping to “like” a photo. While there are high hopes that reconstructing words and music from neural activity could enable applications that promote mental health and social connection, reading and interpreting thoughts is regarded as the next privacy frontier. Uncannily, this reminds me of a popular German cartoon from 1819 titled "The Thinkers Club" (Der Denker-Club) [0] which had the slogan: How long will be thinking allowed?" (Wie lange möchte uns noch das Denken wohl noch erlaubt bleiben?) It was meant to satirize the clamp down on liberal and nationalist ideas by restricting the freedom of assembly and press as a way to follow through the European Restauration after the Napoleonic Wars. In the current asymmetry of giant tech corporations (in bed with government) I find the idea of further breaking any privacy walls whatsoever by trojan horsing it with mental health and social connection and declaring it a new frontier just totally backwards. I think as with liberal and nationalistic ideas back in the day we should value privacy not try just to let it go for ultimately what? Dissolve ourselves into AGI superseding Gaia: Le monde, c'est moi! But maybe I'm the old-fashioned one, here.

- gtwomd 3y agoHas anyone tried quantizing some metric of brain activity (EEG etc.) into a set of tokens, and then training a Transformer model on it? I wonder if hidden in that is some good prior for human-cognition-related activities, i.e. extend the token space to add human language tokens, train on that and see if it trains significantly faster than a randomly initialized model.
- BizarroLand 3y agoI and many other people can create new music in my head by imagining it. I wonder if this could allow me to turn my brain music into an album without needing a 104 part score written out, a full orchestra, and the philharmonic to play and record it live first?
