The invention provides an adaptive space-time neural network traffic prediction model combined with multi-graph fusion. Firstly, three spatial dependencies of DTS are considered, and an initial adjacency matrix is constructed. Secondly, a method of alternately training a graph generation module and a prediction module is adopted, and a loss function with good performance is designed in the training process, so that the model can be self-adjusted. And finally, a fusion mechanism is adopted to fuse the learned matrixes and generate an optimal adjacent matrix, so that the prediction of the road traffic is more accurate.
本发明提出一种结合了多图融合的自适应时空神经网络交通预测模型。首先考虑DTS三种空间依赖关系,构建初始邻接矩阵。其次,采用图生成模块与预测模块交替训练的方法,并在训练过程中设计了性能良好的损失函数,使得模型能够自我调整。最后,本发明还采用了融合机制来融合学习到的矩阵并产生最优邻接矩阵,这使得道路交通的预测更加准确。
