A Unified Framework for Trajectory Prediction with Explicit Planning and Reaction Decomposition
TL;DR
INTraJ is a new framework for trajectory prediction that separates social influence into planning and reaction stages, leading to improved prediction accuracy. It demonstrates significant performance gains on standard benchmarks, particularly in long-horizon consistency.
✦ Why It Matters
Implement INTraJ in your trajectory prediction models to enhance accuracy and reliability in dynamic environments.
Key Takeaways
- Adopt INTraJ for improved trajectory prediction in your applications.
- Utilize the two-stage process to better model social interactions.
- Test INTraJ on standard benchmarks to validate performance gains.
- Explore the publicly available code for integration into your projects.
How It Works
INTraJ operates in two distinct stages: first, it constructs reference trajectories by predicting future behaviors of other agents, which is the planning stage. Then, it makes local adjustments based on the difference between these reference trajectories and actual observed behaviors, known as the reaction stage.
This separation allows for a more nuanced understanding of social interactions in trajectory prediction.
