Non-native permanent resident population identification method based on spectral clustering

Abstract

The invention discloses a non-native permanent resident population identification method based on spectral clustering. The method comprises steps that step (1), the residence data information of handset users is collected; step (2), for the step (1), multiple user residence behavior characteristic variables are constructed; step (3), variable screening for the variables of the step (2) is carried out, and dimensionless processing is further carried out; and step (4), a spectral clustering method is employed to carry out clustering analysis, and a model is established; and the residence data information of the step (1) comprises the residence day number, residence duration and ECI switching data. Statistics of the residence day number, residence duration and the ECI switching data of the users in a present city can be realized according to the collected residence data information, permanent residents and non-permanent residents are different in residence characteristics, so the residence characteristic variables are formed through processing the residence information, the two types of users can be distinguished through employing the clustering algorithm, and the identification result is more scientific.

Description

technical field [0001] The invention belongs to the technical field of communication, and in particular relates to a method for identifying foreign resident population based on spectral clustering. Background technique [0002] With the advancement of economic system reform, the permanent population of migrants in cities has rapidly expanded and has become a special group that cannot be ignored. Permanent resident population, as a statistical caliber, is mainly for regions. The statistical calibers of permanent resident population and registered population are different, and they play different roles in the work of society and government departments. In the current situation where the floating population is large and household separation is common, the resident population can more accurately reflect the population size and current situation of a region, and provide more effective information for the government to formulate relevant policies and service measures. Therefore, ...

[0003] But demographics have always been a laborious and time-consuming endeavor

In the existing identification methods of permanent residents from outside the country, it is mainly completed manually, and the confirmation is done by issuing questionnaires or calling out by telephone. This method not only consumes manpower and material resources, but also is inefficient.

Some operators will also adopt a caliber method to define, but this kind of definition rule lacks scientific explanation
