Why does everyone use *world* models now?
A model in Reinforcement Learning has been clearly defined for decades: given a state s and action a, it produces the next state s' and the reward r(s,a).
what does the *world* do?
🏈Analogy: start QB Pat Mahomes against the D-II AI college and then compare the score with those of Brady vs Mannings.
There are so many moving pieces in neural net optimization that need to be controlled so we are playing in the same 'division':
learning rate, schedule,…
