Predicting the future motion of road participants is crucial for autonomous driving but extremely challenging due to staggering uncertainty. Recently, most forecasting methods resort goal-based strategy, i.e., predicting endpoints trajectories as conditions regress entire trajectories, so that search space solution can be reduced.
