Training another musculoskeletal system @xiaotiansu.bsky.social for tennis, after having trained other musculoskeletal systems for soccer and pingpong. With cognitive function, reward learning, and some sort of teacher distillation, this system learns a quite robust forehand within 36,000 steps👍

Something exciting just left the gym -- meet Arnold the first generalist musculoskeletal control policy! The human body has 600+ muscles, yet we seamlessly coordinate them for everything from whispering a syllable to felling a forrest. How? www.arxiv.org/abs/2508.18066

It’s pretty strange they don’t have this in zurich. At EPFL, all stem master’s students have a mandatory internship, and we get the chance to intern at big tech companies

Quick life update: I recently started my PhD back in the beautiful Lac Léman region at EPFL Campus Biotech. Just wanted to show off the office a bit! 😎 More nature views coming soon…

Stopped by BAAI (Beijing Academy of AI) to visit a friend! ☕️ The coffee was great, and it’s right between China’s top two universities. Sadly, the hanging garden is closed for now. Overall a quite nice place to do research #Beijing

Super interesting example! The trained model seems to understand the colliding better than rolling (the colliding part looks more natural)

Another interesting project I worked on at @icepfl.bsky.social Kudos to @sjaved.bsky.social and all the co-authors! The findings in MQAT highlight the potential of exploiting modularity in neural networks for efficient and performant compression/adaptation. Check out the #TMLR paper for details!

Yeah, back in the day interns at bd had some serious access permissions, but this is taking it too far; still imo retracting the paper is unlikely, I wonder how neurips will react

Perhaps instead of solely focusing on preventing forgetting in AI systems, we should be asking: How can we implement more selective, adaptive forgetting mechanisms similar in a continual learning framework? [4/4] Thoughts? #continual

Chengkun Li @ckli.bsky.social · 09/12/2024
So probably, the real challenge isn't preventing ALL forgetting - it's developing mechanisms to identify which patterns should be preserved vs. discarded. This is where biological systems could excel through social feedback, interactions, expert guidance, and iterative refinement. [3/4]
100
Chengkun Li @ckli.bsky.social · 09/12/2024
In both natural and artificial learning systems, selective forgetting (perturbation/regularization) could help escape local optima and unlearn inefficient or corrupted patterns (especially relevant given concerns about poisoned training data) [2/4]

Chengkun Li @ckli.bsky.social · 09/12/2024
💭When reading continual learning literature, there's always the term 'catastrophic forgetting' being discussed as a major challenge. But looking at some efficient learning systems (e.g. biological-based ones), it's hard to not notice forgetting isn't necessarily a bug - it's sometimes a merit. [1/4]

agree, public double-blind review + public discussions (e.g., OpenReview, AlphaXiv) could help mitigate the issue to some extent
