AMP: Autoregressive Motion Prediction Revisited with Next Token Prediction for Autonomous Driving

Jia, Xiaosong, Shi, Shaoshuai, Chen, Zijun et al.

Understand

As an essential task in autonomous driving (AD), motion prediction aims to predict the future states of surround objects for navigation.

  • One natural solution is to estimate the position of other agents in a step-by-step manner where each predicted time-step is conditioned on both observed time-steps and previously predicted time-steps, i.e., autoregressive prediction.
  • Pioneering works like SocialLSTM and MFP design their decoders based on this intuition.
  • However, almost all state-of-the-art works assume that all predicted time-steps are independent conditioned on observed time-steps, where they use a single linear layer to generate positions of all time-steps simultaneously.
