Amir Bar(@_amirbar):Planning is one of the most exciting uses of world models, but existing planners struggle on long horizons. Introducing GRASP: a fast gradient-based planner for world models that outperforms prior methods on long-horizon tasks. Two key ideas: 1.jointly optimize actions and intermediate subgoals 2.inject stochasticity to explore subgoal space Project page: https://t.co/cXrXTHgF5m Paper: https://t.co/mXE41H21sb w/ @michaelpsenka @mikerabb @ask1729 and @ylecun
