GICNet: Goal Interaction Conditioned Network for Human Trajectory Forecasting
摘要
Pedestrian motion prediction is of critical significance for intelligent and safe autonomous driving systems design. Human movement is by nature highly non-deterministic and multi-modal. Particularly, humans’ travel goals and their behavioral decisions interact with each other. In this work, we present Goal Interaction Conditioned Network GICNet for flexible and accurate human trajectory forecasting. Social influence, multi-modality, and goal constraints have been incorporated into GICNet to infer socially compliant human trajectories. The approach operates in three key stages: learning a probability distribution of motion intentions from historical data, grouping pedestrians and modeling goal-goal interactions using a masked Graph Attention Network (GAT), and integrating intention with motion history for prediction. Additionally, we present a novel iterative pooling method to adaptively fuse the impact of different pedestrian attributes during trajectory generation, enhancing robustness to neighbor misidentification. We demonstrate that GICNet generates realistic multi-modal trajectories, and improves the state-of-the-art performance on the Stanford Drone trajectory prediction benchmark by \(\sim \) 6.7% and on ETH-UCY benchmark by \(\sim \) 23.0% under the Best-of-20 evaluation protocol, significantly outperforming existing probabilistic models in dense interaction scenarios.
