Leapfrog Diffusion Model for Stochastic Trajectory Prediction
Leapfrog Diffusion Model for Stochastic Trajectory Prediction
To model the indeterminacy of human behaviors, stochastic trajectory prediction requires a sophisticated multi-modal distribution of future trajectories. Emerging diffusion models have revealed their tremendous representation capacities in numerous generation tasks, showing potential for stochastic trajectory prediction. However, expensive time consumption prevents diffusion models from real-time prediction, since a large …
