DiffWAM: A Fast and Efficient Navigation World Action Model
DiffWAM is a preprint that introduces a UAV navigation world-action model. It recovers camera trajectories directly from the predictive features of a frozen video model, avoiding future-video decoding and multi-frame geometric reconstruction at deployment. The paper reports a trajectory RMSE of 0.3492 m and adds FastDreamer, an execution system that overlaps computation with flight for continuous UAV control.
