Problems solved by technology
[0004] The inventor found in the research that the forecasting method based on social science has poor practicability due to the complex operation process, while the forecasting method based on association rules has poor applicability due to the limited data volume of the data source, and It is difficult to find the correct prediction result from more association rule results, which reduces the prediction accuracy
In addition, there is currently no perfect solution for predicting juvenile delinquency tendencies with high accuracy and good practicability

The invention provides a behavior prediction method and device. The method comprises the steps that basic attribute information and behavior attribute information of a user are obtained; a mutual information amount between the basic attribute information and the behavior attribute information is calculated; according to the mutual information amount and a discernible matrix, the basic attribute information is reduced to obtain target basic attribute information; on the basis of the cosine similarity and a classification reasonable coefficient, an initial behavior prediction function obtained after Bayes calculation is performed according to the target basic attribute information and the behavior attribute information is updated to obtain a prediction function, the cosine similarity shows a cosine value between the target basic attribute information and the behavior attribute information, the classification reasonable coefficient shows that the target basic attribute information is classified into the reasonable degree of the behavior attribute information; on the basis of the behavior prediction function, the user tendency behavior is predicted, and a prediction result is obtained. On the basis of the improved naive Bayesian algorithm, the reduced information is classified and predicted, and the prediction accuracy and precision are high.
Description
technical field [0001] The present invention relates to the technical field of behavior prediction, in particular to a behavior prediction method and device. Background technique [0002] With the progress of the society and the development of the economy, the phenomenon of juvenile delinquency is increasing day by day, and the crimes are becoming younger, violent and gang crimes. There are many reasons for this social problem, including subjective reasons and objective reasons, that is, school reasons, and social and family reasons. In recent years, from the school shootings in the United States to the several cases of teenagers killing their biological parents, classmates and teachers in my country, all of them are related to juvenile violent crimes. The prevention of juvenile delinquency has become a social problem that cannot be ignored, and has attracted global attention. [0003] The following two juvenile delinquency prediction methods have been proposed in the prio...
