🤖🧠NOW OUT IN PNAS🧠🤖 Language models show many surprising behaviors. E.g., they can count 30 items more easily than 29 In Embers of Autoregression, we explain such effects by analyzing what LMs are trained to do pnas.org/doi/10.1073/pnas.23… Major updates since the preprint! 1/n
At the top is the title of the paper: "Embers of autoregression show how large language models are shaped by the problem they are trained to solve". Below on the left is a screenshot of ChatGPT being asked to count how many words are in a list. The correct answer is 29, but it says 30. Next to it is a plot showing ChatGPT's accuracy at counting elements in a list; in general, it does well on multiples of 10 but poorly on other numbers. The explanation offered at the bottom of the image is: In training sets, round numbers are much more common than other numbers.

Excited to share our NEW preprint: a "brain-to-voice" neuroprosthesis that directly synthesizes voice from neural activity with closed-loop audio feedback. It allowed a man with ALS to speak expressively by modulating intonation & sing melodies via BCI! doi.org/10.1101/2024.08.14.6… 1/

If you are attending SfN in Chicago this year, join our nano symposium on Oct 5th at 1 pm. We have a stellar lineup with @giacomo_valle @LabSomato @SRaspopovic @losborn1 @robert_gaunt1 @lauracrucianel1 @JonathanMuheim @natnatkatic and others I could not find on X :) #neuroscience

Specifically, excited to share that I’ve started a new role as assistant professor at @CWRUBME @cwru and have joined the @HumanFusions team. Get ready for some awesome science.

Overall, this work helps demonstrate the feasibility for enhancing tactile detection of intact peripheral touch pathways degraded by disease or injury.

After 10 years of implanting Utah Arrays in 5 participants with spinal cord injuries… we provide a methodological roadmap to target and evoke tactile finger sensations using intracortical microstimulation. @John_E_Downey @robert_gaunt1 @jenpgh tinyurl.com/S1roadmap 🧵1/7

How do you know if something is wet/dry? Humans have no dedicated sensor for humidity. Instead, we rely -mainly- on thermal cues. Do the test: sit on a cold bench, your first reaction is: The bench is Wet! @ploumitsakou, @JonathanMuheim, @_smicera, @yonderboy_ , @thermosenselab
