Detailed Description
In this embodiment, referring to fig. 1, the method for identifying social group behaviors based on electromagnetic spectrum data mining includes the following steps:
s1, acquiring the frequency band occupancy rate of radio communication performed in a first area;
s2, acquiring characteristic data of social group behaviors in a first area;
s3, extracting an optimal feature subset from the feature data;
s4, determining a correlation between the frequency band occupancy rate and the optimal feature subset through a geographical weighted regression model;
s5, performing time-varying behavior analysis on the optimal feature subset through a time sequence model to obtain a first time sequence;
s6, according to the correlation between the frequency band occupancy rate and the optimal feature subset and the first time sequence, constructing a social group behavior prediction model by using a deep learning model;
and S7, using the social group behavior prediction model to identify the social group behaviors.
The principle of steps S1-S7 is shown in FIG. 2.
Step S1, namely the step of acquiring the frequency band occupancy rate of the radio communication performed in the first area, specifically includes the following steps:
s101, determining the position of a first area where a signal source is located through an AOA/TDOA algorithm;
s102, in a first area, acquiring electromagnetic spectrum monitoring data by monitoring mobile wireless communication equipment;
and S103, calculating the frequency band occupancy rate according to the electromagnetic spectrum monitoring data.
Before executing steps S101-S103, data preprocessing may be performed to convert the existing spectrum data into a format easy to calculate, retain necessary information, and remove redundant information, so that the format normalization of the spectrum data can be realized, the storage space is reduced, and the subsequent calculation speed is increased. The flow and principle of steps S101-S103 are: in step S101, performing region classification on the obtained spectrum data, locating a spatial position of a signal source, adjusting parameters related to the signal source through an AOA/TDOA algorithm, and obtaining spectrum data belonging to a specific region in combination with assistance of geographic information, so as to obtain high-precision regional social group behaviors, where the signal source may be a mobile phone, a tablet computer, a bluetooth headset, a smart bracelet, or other device using electromagnetic wireless communication, and the first region refers to a specific region, for example, a region where a certain specific crowd uses the mobile phone, the tablet computer, the bluetooth headset, the smart bracelet; in step S102, the electromagnetic spectrum monitoring data may be acquired by a communications carrier, or the mobile wireless communications device may be monitored by using an instrument set by a third party without the communications carrier, so as to acquire the electromagnetic spectrum monitoring data, and the frequency band occupancy rate of the specific region, that is, the first region, is calculated according to the spectrum data in the region.
Step S2, namely the step of obtaining the characteristic data of the social group behavior in the first area, specifically includes the following steps:
s201, measuring crowd activity track data in a first area;
s202, carrying out relevance analysis, factor analysis or clustering analysis on the crowd activity track data, and taking the obtained result as characteristic data.
The principle of steps S201-S202 is that: the data of social group behaviors in a specific area, such as crowd activity track data, can be measured in advance through a satellite positioning system or a base station positioning system installed on a mobile phone, and then characteristic data which is obviously related to the social group behaviors is extracted through correlation analysis, factor analysis, a cluster analysis method and the like, so that frequency spectrum data characteristics which are obviously related to the social group behaviors can be obtained.
Step S3, namely, the step of extracting the optimal feature subset from the feature data specifically includes the following steps:
and S301, performing dimension reduction processing on the feature data by using a principal component analysis method to obtain an optimal feature subset.
The feature data is further subjected to dimensionality reduction by adopting a principal component analysis method to obtain an optimal feature subset, the optimal feature subset is used in the subsequent steps, the feature data is not used any more, and the calculated amount of a training model can be reduced.
In step S4, correlation analysis is performed on the frequency band occupancy degree and the optimal feature subset through the geographic weighted regression model, so as to determine a correlation relationship between the frequency band occupancy degree and the optimal feature subset. The optimal characteristic subset is extracted from the characteristic data, the optimal characteristic subset comprises the characteristic information of the social group behaviors, and the frequency band occupation degree is measured from the radio communication used by the crowd and comprises the phenomenon information of the social group behaviors, so that the correlation between the frequency band occupation degree and the optimal characteristic subset represents the corresponding relation between the phenomenon information and the characteristic information of the social group behaviors. In step S4, the correlation between the occupancy rates according to the frequency bands and the optimal feature subsets may also be visualized through a geographic information system.
In step S5, a time-varying behavior analysis is performed on the optimal feature subset through a time series model, so as to obtain a first time series. In step S5, a time series model is used to model social group behaviors in a specific area for time-varying behavior analysis, wherein the selection of the specific area may use city POI data, i.e., to select a socially significant geographic location, such as a mall, a school, a sight spot, etc. The obtained first time series includes a plurality of data having the same properties as the optimal feature subset.
Step S6, namely, the step of constructing a social group behavior prediction model using a deep learning model according to the correlation between the frequency band occupancy and the optimal feature subset and the first time sequence, specifically includes the following steps:
s601, determining a second time sequence corresponding to the first time sequence according to the correlation between the frequency band occupancy rate and the optimal feature subset;
s602, taking the second time sequence as the input of the deep learning model, taking the first time sequence as the expected output of the deep learning model, and training the deep learning model;
and S603, taking the trained deep learning model as a social group behavior prediction model.
In step S601, according to the data with the same properties as the optimal feature subset included in the first time sequence and the correlation between the frequency band occupancy rate and the optimal feature subset, data with the same properties as the frequency band occupancy rate may be obtained, and these data form a second time sequence. According to the nature of the data contained in the first time series and the second time series, the second time series can be used as the input of the deep learning model, and the first time series can be used as the expected output of the deep learning model to train the deep learning model. Specifically, a Recurrent Neural Network (RNN), a Graph Neural Network (GNN), a decision tree model, a random forest model, a markov model, an ARMA model, or the like may be used as the deep learning model. When the deep learning model is trained, data in the second time sequence can be input into the deep learning model, the data is processed by the deep learning model and then output, the output result of the deep learning model is compared with the expected output, parameters of the deep learning model are reversely transmitted according to errors, and the deep learning model is stopped from being trained until the error between the output result of the deep learning model and the expected output is smaller than a preset threshold value.
The trained deep learning model is the social group behavior prediction model in the embodiment, and the obtained social group behavior prediction model has the capability of identifying the social group behavior characteristics according to the frequency band occupancy degree.
Step S7, namely, the step of using the social group behavior prediction model to perform social group behavior recognition, specifically includes the following steps:
s701, acquiring the frequency band occupancy rate of radio communication performed in a specific area within a period of time;
s702, inputting the frequency band occupancy rate into a social group behavior prediction model;
and S703, determining the characteristics of the social group behaviors according to the output result of the social group behavior prediction model.
The specific region in step S701 may refer to a city, a country, or even the world, and the period of time may refer to a fixed time such as a specific year, month, and day, or may refer to a duration of a certain event. For example, when step S701 is executed, the time and place where a short-term significant event occurs may be selected for analysis, such as a concert held in a certain city, a traffic jam occurring on a certain road, and the like, and changes of electromagnetic data and social group behaviors under these scenes are observed; or selecting a longer special period, such as a global infectious disease pandemic period, an urban heat wave duration period and the like for analysis.
By executing steps S701 to S703, the characteristics of the social group behaviors of a region may be obtained according to the frequency band occupancy degree generated when the region uses a mobile phone or other wireless communication device within a period of time, wherein the content of the characteristics of the social group behaviors is the same as the characteristic data used in step S2 when the social group behavior prediction model is obtained by performing the training of steps S1 to S6, and based on the recognition result of the characteristics of the social group behaviors, appropriate opinions and suggestions are provided, such as people flow dispersion decision arrangement, and the like. The method can be used for analyzing social group behaviors through electromagnetic spectrum data and has multiple purposes. If the analysis precision is accurate enough, the method can be used for searching and rescuing trapped people in disaster areas after disasters such as earthquake and the like occur. By accumulating electromagnetic spectrum data for a long period of time in a certain area, when a major emergency occurs, the influence caused by the event can be analyzed. Similarly, if the electromagnetic spectrum data of a certain area is detected to be abnormal in a larger range, the area can be investigated to judge whether a special event occurs.
The social group behavior recognition method in this embodiment can be applied to the monitoring platform shown in fig. 3, and the social group behavior distribution monitoring platform based on electromagnetic spectrum data mining analyzes spectrum data by combining multi-dimensional information of time domain, frequency domain and spatial domain, and can provide prior knowledge for radio. Through the construction and distribution of the platform, a radio supervision department can realize effective spectrum management, and the social group behavior distribution of the region is reflected laterally by calculating the occupancy rate of a target frequency band.
Referring to fig. 4, 5, and 6, in this embodiment, the main operating frequency bands of three mobile communication carriers, namely, a first mobile communication carrier, a second mobile communication carrier, and a third mobile communication carrier in china, are selected as target frequency bands to explain the application of the social group behavior identification method. Fig. 4 shows the main operating frequency band of a first mobile communication carrier, fig. 5 shows the main operating frequency band of a second mobile communication carrier, and fig. 6 shows the main operating frequency band of a third mobile communication carrier.
The social group behavior recognition method in the embodiment is applied to regions such as Wenchang city, Suiyuan city, Lingshui city, Yanghui city and eastern city in Hainan province of China, and social group behaviors in the regions at a certain time period are recognized. The frequency band occupancy of the nearby target frequency band is monitored at the monitoring points in the above-mentioned region, so that step S1 of the social group behavior identification method in the present embodiment is executed. Specifically, the monitoring points located in the areas such as the haikou city, the near-high county, the east city and the like are mainly located in residential places such as a residential district, a dormitory and the like, and the monitoring points located in the autonomous counties such as the wenchang city, the san city and the tomb water are mainly located in places such as the centers of the wenchang dragon building, the san libuan road and the tomb water autonomous counties. Different color depths are used for representing the occupancy rate of the target frequency band in the corresponding region, the darker the color is, the higher the utilization rate of the target frequency band in the region is, and the larger social group behaviors in the region are further reflected from the side.
Fig. 7 shows the analysis results obtained by applying the social group behavior recognition method in this embodiment to the above-described region. As can be seen from fig. 7, the frequency band occupancy of the wenchang city, the san city, and the mausoleum county is slightly higher than the frequency band occupancy of the haikou city, the near-high county, and the east city. According to the principle of the social group behavior recognition method in the present embodiment, it is considered that the social group characteristics of the city of Wenchang, the city of Suiyuan and the autonomous region of the Ling water shown in FIG. 7 are more obvious than the social group characteristics of the city of Haikou, the city of Bighua and the city of Orient. Since the monitoring points in the areas such as the haikou city, the lingao county, the eastern city and the like are mainly located in the residence such as the residential quarter, the dormitory and the like, the social group behaviors of the places are relatively inactive, and the monitoring points in the wenchang city, the san franchise city and the mausoleum are mainly located in the places such as the wenchang dragon building, the san libitum way and the mausoleum county center and the like, the social group behaviors of the places are relatively active, so that the conclusion obtained by the social group behavior identification method in the embodiment is consistent with the actual situation, which proves the feasibility of the social group behavior identification method in the embodiment.
The method for identifying the social group behaviors based on the electromagnetic spectrum data mining can write a computer program according to the method for identifying the social group behaviors based on the electromagnetic spectrum data mining, write the computer program into a memory or an independent storage medium of a computer device, and instruct a processor to execute the method for identifying the social group behaviors based on the electromagnetic spectrum data mining after the computer program is read out, so that the technical effect which is the same as that of the embodiment of the method is realized.
