- Abstract: A crime is a punishable offence that is harmful for an individual and his
society. It is obvious to comprehend the patterns of criminal activity to
prevent them. Research can help society to prevent and solve crime activates.
Study shows that only 10 percent offenders commits 50 percent of the total
offences. The enforcement team can respond faster if they have early
information and pre-knowledge about crime activities of the different points of
a city. In this paper, supervised learning technique is used to predict crimes
with better accuracy. The proposed system predicts crimes by analyzing data-set
that contains records of previously committed crimes and their patterns. The
system stands on two main algorithms - i) decision tree, and ii) k-nearest
neighbor. Random Forest algorithm and Adaboost are used to increase the
accuracy of the prediction. Finally, oversampling is used for better accuracy.
The proposed system is feed with a criminal-activity data set of twelve years
of San Francisco city.

Prediction [60.508960752148454]
This work proposes a Spatial-Temporal Hypergraph Self-Supervised Learning framework to tackle the label scarcity issue in crime prediction.
We propose the cross-region hypergraph structure learning to encode region-wise crime dependency under the entire urban space.
We also design 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.

We propose Spatial-Temporal Sequential Hypergraph Network (ST-SHN) to collectively encode complex crime spatial-temporal patterns.
In particular, to handle spatial-temporal dynamics under the long-range and global context, we design a graph-structured message passing architecture.
We conduct extensive experiments on two real-world datasets, showing that our proposed ST-SHN framework can significantly improve the prediction performance.
