Problems solved by technology

[0004] 1. The selection of features depends on human intuition, which increases the uncertainty of modeling and directly affects the research and judgment results
[0005] 2. The data processing process is cumbersome and time-consuming. In the context of big data, the processing of massive, heterogeneous, and scattered data is particularly significant

Embodiment Construction

[0054] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0055] Such as figure 1 As shown, a method for researching and judging high-risk criminals in this embodiment includes the following steps:

[0056] Step 1, generate a deep feature set of high-risk criminals according to the acquired personnel characteristics;

[0057] Step 2, preprocessing and dimensionality reduction of the deep feature set to obtain key features;

[0058] Step 3, establish a research and judgment model for high-risk criminals through key features;

[0059] Step 4, optimizing the research and judgment model in step 3;

[0060] Step 5, through the optimized research and judgment model, conduct research and judgment on the target person, and determine whether the target person is a high-risk crimin...

Abstract

The invention relates to a method and system for studying and judging high-risk criminal personnel. The method comprises the following steps: step 1, generating a depth feature set of high-risk criminal personnel according to obtained personnel characteristics; step 2, performing preprocessing and dimensionality reduction on the depth feature set to obtain key features; step 3, establishing a studying and judging model of the high-risk criminal personnel through the key features; step 4, optimizing the studying and judging model in the step 3; and step 5, studying and judging the target personnel through the optimized studying and judging model to judge whether the target personnel is the high-risk criminal personnel. By adoption of the method, the feature set of the high-risk criminal personnel is automatically inferred and synthesized to enhance the representation depth of the high-risk characteristics of the personnel, and a targeted modeling method is adopted for different crime types to achieve accurate studying and judging.

Description

technical field [0001] The invention relates to the field of big data analysis of public security, in particular to a method and system for researching and judging high-risk criminals. Background technique [0002] The research and judgment of high-risk criminals is of great significance in the field of public security. It aims to establish a research and judgment model through the analysis and induction of personnel characteristics to achieve the purpose of identifying high-risk criminals. In the context of big data, the storage of massive information greatly expands the depth of personnel information, covering social, travel, financial transactions and other fields, providing multi-directional and in-depth information support for the research and judgment of high-risk criminals. Scattered and isolated make its utilization rate low, unable to give full play to the value of information. [0003] The existing high-risk personnel research and judgment technology is mainly bas...
