Abstract

The invention relates to a prisoner dangerous behavior prediction method and system based on effective influence factors. The method comprises the following steps: (1) structured processing: 1) data cleaning, and 2) extracting of effective influence factors; (2) dangerous behavior prediction based on weight scores: firstly, classifying all to-be-assessed personnel, and secondly, in combination with prison administration business, managers often pay attention to a small part of groups with extremely high dangerous behaviors and dangerous behavior prediction and early warning based on weight scores; and (3) carrying out online optimization on the Random Forest model. According to the method, analysis and screening are carried out from two aspects of data correlation of evaluation personnel and information entropy provided by fields, and important factors for dangerous behaviors of the prisoners are mined. The method and the system can reduce the calculation complexity and model complexity, and improves the evaluation and prediction accuracy and effectiveness.

Description

technical field

[0001] The invention relates to a method and system for predicting dangerous behaviors of inmates based on effective influencing factors, belonging to the technical field of prison administration, and in particular to a research method for predicting dangerous behaviors in prisons. Background technique

[0002] Prison management in prisons plays an important role in prison work. Under the current social situation, in addition to doing a good job in the reform of inmates, it is also very important to monitor the daily behavior and risk assessment of inmates in prison. This is a guarantee It is a fundamental part of the safety of the prison environment and the promotion of good reform of personnel. Routine risk prediction and assessment work mainly includes: suicide risk, escape risk, violence risk, etc. At present, this work in the prison administration mainly relies on the observation and evaluation of the police officers in the prison area, and the paper qu...
