Problems solved by technology

At the same time, geographical regional differences make it impossible to use a unified grid. When using model predictions, the existing method is to manually adjust the grid size, resulting in poor prediction results and low prediction efficiency.

Abstract

The invention discloses an urban financial invasion case prediction system and prediction method based on a space-time scale adaptive model. The system comprises a model calculation task management module, a model definition module, a model training module, a model prediction module, a prediction result display module and a model registration module. The method comprises the following steps: (1) carrying out pyramid hierarchical grid statistics on urban financial invasion cases; (2) analyzing spatial and temporal distribution characteristics of urban financial invasion cases; (3) adaptively determining the space-time scale of the urban financial invasion case prediction model; and (4) constructing an ST-ResNet-based urban financial invasion case prediction model as a demonstration. The method is helpful for revealing crime geographical differentiation characteristics, can meet the requirements of different crime prediction precisions, and achieves the optimal arrangement of police patrol work.

Description

technical field [0001] The invention relates to the technical field of model calculation, in particular to a system and method for predicting urban property infringement cases based on a time-space scale self-adaptive model. Background technique [0002] With the continuous development of human civilization, especially the rapid progress of modern science and technology since the industrial revolution, crimes have undergone tremendous changes in terms of number and scale, crime methods and the degree of harm to society. The threat is also becoming more and more serious. Taking my country as an example, the total amount of crimes has remained high in recent years. According to statistics, the crime rate in China has been on the rise year by year over the past two decades. . Although the crime situation has gradually stabilized since 2010, crimes such as theft, snatching, robbery, and fraud, which are collectively referred to as property infringement cases by the public secur...
