About this paper

Junzhe Wang, Jinqing Zhang, Qingjie Liu

RFWorld scores candidate paths by querying a shared scene memory rather than generating a separate future for each path. During training, semantic maps at current and future times supervise memory; at inference, waypoints retrieve features. On the NAVSIM test, it reaches a PDMS of 90.5 and 37.5 ms at 1,024 candidates; the comparison does not isolate the mechanism’s effect.
