Complex Dynamic Spatial Temporal Correlation A The Nodes Represent (a) the nodes represent the locations of different observation points in the road network, observation point 3 is the predicted location of interest, and nodes 1, 2, and 4 are the location of. Additionally, we integrate a long and short term convolution module to capture temporal correlations at the individual node level. this dual module design allows ctgsan to not only capture the complex spatial dependencies but also effectively model the temporal dynamics, leading to more accurate predictions.
Complex Dynamic Spatial Temporal Correlation A The Nodes Represent Traffic flow data exhibits highly complex spatiotemporal characteristics due to the intricate spatial correlations between nodes and the significant temporal dependencies across different. This paper proposes a complex correlation matrix to replace the traditional adjacency matrix to represent the complex relationship between different nodes better. We construct a node correlation estimator using multi head self attention and linear transformations to learn the dynamic spatiotemporal correlations between nodes. Additionally, constrained by spatial heterogeneity, most studies fail to consider distinct spatial temporal patterns of each node. to overcome these limitations, we propose a spatial temporal interactive dynamic graph convolutional network (stidgcn) for traffic forecasting.

Imputation interpolation: time series models, sparse learning (e.g., matrix tensor factorization), deep learning (e.g., generative models), etc. unsupervised pattern discovery: dynamic mode decomposition in dynamical systems, matrix tensor factorization, etc. With the trafic flow data at each day and each node of the road network, we can represent the dynamic spatial depen dency among nodes by capturing the correlation attributes between the probability distributions of each node, using. The gcn are em ployed to capture spatial correlations among nodes, while the disentangled temporal module interprets complex tem poral patterns as seasonal and trend patterns. This framework combines a dynamic graph generator with a dynamic graph recurrent neural network and a novel fusion mechanism, enabling it to capture complex dynamic spatiotemporal dependencies while integrating both static and dynamic graph features.
