Revisiting Numerical Forecasting Models for Language-Based Trajectory Prediction

Language-based trajectory predictors represent coordinates as discrete tokens and learn auxiliary tasks such as destination and group reasoning.

Key points

  • This formulation enables the model to capture behavioral intent and social context beyond coordinate dynamics alone.
  • To address this limitation, we introduce MoRE (Mixture of Reward Experts), a refinement framework that transfers numerical forecasting priors into a pretrained language-based predictor through reinforcement learning.
  • Five frozen numerical predictors provide complementary coordinate-level knowledge of motion and interactions.
  • A ground-truth reward anchors the prediction to the target trajectory.
