Diverse Yet Consistent: Context-Guided Diffusion with Energy-Based Joint Refinement for Multi-Agent Motion Prediction
Summary
The CODA framework introduces a novel approach to multi-agent motion prediction, leveraging context-guided diffusion with energy-based joint refinement to generate predictions that are both diverse and jointly consistent. This deep generative model addresses challenges in capturing multimodal distributions and ensuring interaction consistency among agents. CODA integrates Dynamic Context as Guidance Condition (DCGC) and an Adaptive Condition Integration Module (ACIM) to enhance diversity, alongside a Joint Distribution Refinement (JDR) module using an energy-based formulation to enforce consistency. Extensive experiments on four benchmark datasets—ETH/UCY, SDD, NBA, and JRDB—demonstrate CODA's superior performance. It achieved the lowest average error (0.17/0.28) on ETH/UCY, a 15.0%/12.5% improvement over MoFlow (0.20/0.32), and established state-of-the-art marginal performance on SDD (ADE 6.87, FDE 10.86) and NBA (ADE/FDE at 4.0s: 0.69/0.87), while maintaining competitive joint metrics.
Key takeaway
For Machine Learning Engineers developing multi-agent systems, especially in autonomous driving or robotics, CODA offers a robust method to improve trajectory forecasting. Its context-guided diffusion and energy-based refinement approach allows you to generate predictions that are both diverse and jointly consistent, which is crucial for safety and reliability. You should consider adopting this framework to balance individual agent plausibility with overall interaction coherence in your multi-agent motion prediction models.
