This paper proposes a neural refiner that corrects the output of existing motion forecasters for autonomous driving by modeling each candidate future as a graph with bidirectional temporal edges, so later segments can revise earlier ones in a single pass. Its main selling point is that it works as a backbone-agnostic add-on, with reported gains on Argoverse2 and Waymo Open Motion Dataset benchmarks. Readers should weigh the leaderboard results against the usual caveats of benchmark-specific architecture work, such as the "standard-input" comparison constraint and the unreported cost of added inference compute.
FutureLift: Lifting Trajectory Proposals into Bidirectional Future Graphs for Motion Forecasting
arXiv:2610.22215v1 Announce Type: cross Abstract: Accurate motion prediction is critical for safe autonomous driving, yet even strong forecasters leave residual errors in their multimodal proposals. Existing refiners compress complete proposals or update their segments sequentially, preventing the full proposed future from serving as explicit relational context for correction. We introduce FutureLift, a backbone-agnostic refiner that represents each multimodal proposal as a heterogeneous future graph, with spatially grounded temporal nodes connected to agent histories, map elements, alternative modes, and, for joint prediction, other agents future trajectories. Bidirectional temporal edges allow later evidence to revise earlier segments in a single pass, and the updated nodes predict residual coordinate and confidence corrections. Requiring only proposals, scores, and scene context, FutureLift provides a common refinement interface for structurally different forecasting backbones. On Argoverse2 and the Waymo Open Motion Dataset, it consistently improves frozen proposals and outperforms native and specialized refiners across marginal and joint forecasting. On the WOMD motion-prediction leaderboard, FutureLift ranks first in minADE (0.5049m) and minFDE (0.9942m) among the compared standard-input methods, without LiDAR or ensembling, while achieving a competitive 0.4874 Soft mAP.
