多目标时空预测是动态场景中目标演化与决策的关键。传统静态方法难以捕捉动态环境下多目标间的动态时空演变过程。而神经常微分方程(Neural Ordinary Differential Equation,Neural ODE)网络虽适配动态系统,但在多目标时空关联方面仍存局限。为此提出一种基于改进Neural ODE网络的动态多目标时空预测算法,将Neural ODE与稀疏图卷积网络相结合,建立动态多目标时空预测架构。利用稀疏图卷积网络从历史观测轨迹中提取多目标之间的稀疏时空交互特征,实现对多目标时空关联间的建模;利用Neural ODE灵活高效的时序建模能力对目标的高维隐藏状态进行时序建模,得到多目标的时空预测轨迹。实验结果表明,所建模型在ETH/UCY数据集上的平均位移误差和最终位移误差分别为0.36和0.56,相较于基准模型Neural ODE,本文模型具有更低的预测误差,验证了所提方法的有效性。
Spatio-temporal prediction of multi-targets is the key to target evolution and decision-making in dynamic scenarios. Traditional static methods are unable to capture the dynamic spatiotemporal evolution of multiple targets in dynamic environments. The neural ordinary differential equation (neural ODE) network has limitations for modeling the spatiotemporal correlations among multiple objectives although it is well-suited for dynamic systems. Therefore, this paper proposes a dynamic multi-target spatio-temporal prediction algorithm based on the improved neural ODE network. A dynamic multi-target spatio-temporal prediction architecture is established by combining the neural ODE and the sparse graph convolutional network. Firstly, the sparse graph convolutional network is used to extract the sparse spatio-temporal interaction features among multiple targets from historical observation trajectories, thereby achieving the modelling of multi-target spatio-temporal correlations. Then the flexible and efficient temporal modelling capability of the neural ODE is used to temporally model the high-dimensional hidden states of the targets. Finally, the spatio-temporal prediction trajectories of the multiple targets are obtained. Experiments show that the average displacement error (ADE) and final displacement error (FDE) of the proposed model on the ETH/UCY dataset are 0.36 and 0.56. The proposed model exhibits lower prediction error compared with the neural ODE network model,thus validating the effectiveness of the proposed method.
