It’s pretty incredible how animalistic its behaviors are becoming (hesitating for a moment at the edge of a lip, coiling it’s back legs for increased actuation, and when it almost misses the high jump and moves its back leg really fast multiple times to give itself a tiny boost each time until it recovers). Is that because it’s trained on animal behaviors? Or is this emergent behavior and animals just also do it more or less optimally already?


It trains from scratch (no imitation-learning or hand-written policies to bootstrap off of), so it's all emergent: https://extreme-parkour.github.io/resources/parkour.pdf#page...


it suggests that animals learn using similar neural nets.


Or it simply suggests that this is advantageous behaviour and that different learning methodologies would result in the same behaviour.
