Adam J Calhoun @neuroecology.bsky.social · 26/12/2024What makes fish fast? Can we design robots that make use of designs found in nature (biomimetic)? -> this article claims that the rough shark skin is more efficient, but it also compares it to the smooth skin of fast tuna or swordfish. So why don't they have rough skin?! 100

Reposted by Adam J CalhounSurya Ganguli @suryaganguli.bsky.social · 07/12/2024I always found this paper kind of nice: www.science.org/doi/10.1126/... it shows that if the environment fluctuates then evolution will favor sensors and the mutual info between sensors and env increases fitness. If the env has memory, I suspect organismic memory will provably be selected for alsoscience.orgPhenotypic Diversity, Population Growth, and Information in Fluctuating EnvironmentsOrganisms in fluctuating environments must constantly adapt their behavior to survive. In clonal populations, this may be achieved through sensing followed by response or through the generation of div... 210816

Reposted by Adam J CalhounViswanath (Vish) Sivakumar @seasonedschemer.bsky.social · 05/12/20247/ Our baseline model built using standard techniques from the Speech Recognition literature shows that, with some personalization on top of a model pretrained with 100 subjects, we can quite accurately enable typing with sEMG, eventually without a physical keyboard. 111
Reposted by Adam J CalhounViswanath (Vish) Sivakumar @seasonedschemer.bsky.social · 05/12/20246/ Towards that goal, we now release emg2qwerty - a wrist sEMG dataset collected while touch typing on a QWERTY keyboard. With 108 subjects, 1,135 sessions, 346 hours, and 5.2 million keystrokes, this is quite large by neuroscience standards. arxiv.org/abs/2410.20081 github.com/facebookrese... 111
Reposted by Adam J CalhounViswanath (Vish) Sivakumar @seasonedschemer.bsky.social · 05/12/20245/ But can we further push the boundaries of what is possible with sEMG? We imagine many other applications for sEMG, including the ability to manipulate objects in AR or write full messages as quickly as—or faster than—typing on a keyboard, with very little effort. 101
