• The paper introduces open-world motion forecasting, a novel setting where new object classes are sequentially introduced over time and future trajectories are estimated directly from camera images.method 95%
  Evidencepartial

  In this work, we bridge this fundamental gap by introducing open-world motion forecasting, a novel setting in which new object classes are sequentially introduced over time and future object trajectories are estimated directly from camera images.

• The proposed framework is the first end-to-end class-incremental motion forecasting framework to mitigate catastrophic forgetting while learning to forecast newly introduced classes.technical 90%
  Evidencepartial

  We tackle this setting by proposing the first end-to-end class-incremental motion forecasting framework to mitigate catastrophic forgetting while simultaneously learning to forecast newly introduced classes.

• The framework uses a pseudo-labeling strategy with vision-language model filtering to handle new class introduction.method 85%
  Evidencepartial

  When a new class is introduced, our framework employs a pseudo-labeling strategy to first generate motion forecasting pseudo-labels for all known classes which are then processed by a vision-language model to filter inconsistent and over-confident predictions.

• The approach uses a novel replay sampling strategy that leverages query feature variance to sample previous sequences with informative motion patterns.method 85%

  Parallelly, our approach further mitigates catastrophic forgetting by using a novel replay sampling strategy that leverages query feature variance to sample previous sequences with informative motion patterns.

• The approach supports zero-shot transfer to real-world driving and naturally extends to end-to-end class-incremental planning.technical 80%
  Evidencepartial

  Further, we demonstrate that our approach supports zero-shot transfer to real-world driving and naturally extends to end-to-end class-incremental planning, enabling continual adaptation of the full autonomous driving system.

  Implicationpartial

  Claimed capability with some inference required about what 'naturally extends' means
