An analysis study is introduced by combining the findings of Denver crimes dataset with its demographics information in order to capture the factors that might affect the safety of neighborhoods and to help agencies to predict future crimes in a specific location within a particular time.
AIST, an Attention-based Interpretable Spatio Temporal Network for crime prediction, which models the dynamic spatio-temporal correlations for a crime category based on past crime occurrences, external features and recurring trends of crime.
A purely attentional approach to extract both short-term dynamics and long-term semantics of event propagation through two observation angles, and introduces a novel Frobenius norm-based contrastive learning objective to improve latent representational generalization.
A new generative model applicable to any spatiotemporal data with graph convolutional gated recurrent units (Graph-ConvGRU) and multivariate Gaussian distributions is introduced and crime can be predicted in any resolution as the first time in the literature.
To handle spatial-temporal dynamics under the long-range and global context, the proposed ST-SHN framework designs a graph-structured message passing architecture with the integration of the hypergraph learning paradigm and introduces a multi-channel routing mechanism to learn the time-evolving structural dependency across crime types.
This paper proposes multi-graph fusion networks (MGFN) to enable the cross domain prediction tasks, and designs the multi-level cross-attention mechanism to learn the comprehensive embeddings from multiple mobility patterns based on intra-pattern and inter-pattern messages.
This work proposes a Spatial-Temporal Self-Supervised Hypergraph Learning framework (ST-HSL), and designs the dual-stage self-supervised learning paradigm, to not only jointly capture local- and global-level spatial-temporal crime patterns, but also supplement the sparse crime representation by augmenting region self-discrimination.
This work proposes an Explainable Spatio-temporal graph neural networks framework that enhances STGNNs with inherent explainability, enabling them to provide accurate predictions and faithful explanations simultaneously, and demonstrates that the STExplainer outperforms state-of-the-art baselines in terms of predictive accuracy and explainability metrics.
This work proposes a new spatio-temporal contrastive learning (CL4ST) framework to encode robust and generalizable STG representations via the STG augmentation paradigm and designs the meta view generator to automatically construct node and edge augmentation views for each disentangled spatial and temporal graph.
Adding a benchmark result helps the community track progress.
