Description
TECHNICAL FIELD
[0001] The application belongs to the technical field of social network analysis and complex system modeling, and particularly relates to a social network popularity prediction method and system based on high-order nonlinear dependence. BACKGROUND
[0002] Topic popularity prediction is an important research direction in social network analysis and computational social science. Existing research has made extensive studies on the popularity prediction problem in social networks and has achieved good results, but there are still many deficiencies.
[0003] Firstly, due to the large scale and complex structure of social networks, in the topic popularity prediction problem, a topic is usually related to a large number of posts, and its popularity is affected by a large number of post information. Existing research usually focuses on the popularity evolution process of a single post information in the social network, but cannot analyze the propagation of each related post one by one to predict the popularity of the topic.
[0004] Secondly, in social networks, the popularity of a topic is not only affected by post information, but also follows the natural evolution law of topics in social networks. External incentives and natural evolution are coupled, which makes it more difficult to model and predict the popularity of topics in social networks. Existing methods are difficult to model both factors, which hinders the further improvement of the accuracy of popularity prediction.
[0005] Finally, deep learning is the dominant method for modeling such complex time series data. However, current deep learning models usually perform as a black box, composed of linear and nonlinear functions, which cannot explicitly capture the inherent dynamic structure in real-world nonlinear systems, limiting their interpretability.
[0006] In summary, the main problems of existing models in topic popularity prediction include the large number of posts affecting the popularity of topics, and the popularity change is affected by many factors. These problems limit the effectiveness and interpretability of the model in practical applications, affecting the understanding and trust of users on the prediction results of the model. SUMMARY

[0054] The main problems of the existing model in topic popularity prediction include that the number of posts affecting the topic popularity is huge, and the popularity change is affected by many factors, which limits the effectiveness and interpretability of the model in actual application, and affects the understanding and trust of users on the prediction results of the model. Therefore, the present application provides a social network popularity prediction method based on high-order nonlinear dependence, which regards the topic popularity prediction in a social network as an output prediction problem of a complex dynamic system under external excitation, and uses a polynomial integral network for modeling, realizes accurate prediction of the evolution law of topic popularity under the action of related posts, and effectively improves the prediction accuracy of topic popularity.
[0055] The social network popularity prediction method based on high-order nonlinear dependence provided by the embodiments of the present application, as shown in Figure 1 Firstly, topic related data including topic ranking and post information is acquired and preprocessed, and then the preprocessed data is input into the trained popularity prediction model to output topic popularity prediction results.
[0056] The training of the popularity prediction model includes:
[0057] Data preprocessing: acquiring topic related data within a set time length and preprocessing the topic related data;
[0058] Multi-dimensional feature construction: high-order polynomial features of the preprocessed historical sequence are calculated by using Volterra features to generate multi-order tensor interaction features;
[0059] Multi-channel linear transformation: a learnable discrete Volterra coefficient matrix is set, polynomial integral modeling is independently performed on each order of tensorization interaction feature channel, and the outputs of each channel are linearly aggregated and projected to the original feature dimension space of the input time sequence to obtain the topic popularity prediction result.
[0060] The popularity prediction model provided by the application aims to accurately predict the future popularity of topics and related post information, intuitively express variable relationships, perform detailed variable influence analysis, and provide effective system optimization strategies, thereby improving the accuracy of prediction and helping various organizations and individuals better understand social network dynamics, thereby making more intelligent choices in information dissemination, decision making, and resource allocation.
[0061] First, as shown in Figure 2 and 3 indicate that after the topic-related data is preprocessed, the topic-related data is input into the popularity prediction model, the topic-related data including the number of reposts, the number of comments, the number of likes, whether it is a repost, the sentiment score, and the topic ranking. The popularity prediction model processes the topic-related data to predict the topic popularity in the future period of time and the important parameters such as the number of reposts, the number of likes, and other post information related to the future topic that we need.
[0062] Further, the topic-related data is serialized, for example, the topic ranking is serialized to obtain where t is the length of the observed historical data, is the ranking of the topic popularity at time t. For another example, other post information is serialized to obtain where t is the length of the observed historical data, d is the dimension of each observation at time t, represents a d-dimensional vector composed of each observation at time t, and R represents the real number field.
[0063] It should be noted that after the topic-related data is serialized, each feature sequence is a sequence with a length of T and a dimension of 1, and has a shape of [T, 1]; D feature sequences are spliced into a multi-dimensional feature sequence to obtain a multi-dimensional feature sequence with a shape of [T, D].
[0064] As a preferred, the data preprocessing cleans, processes outliers and missing values of the input data set, ensures data quality, normalizes the data, makes the input data have more stable gradients, and reduces the magnitude difference between features, thereby improving the accuracy of the model.
[0065] Next, in the multidimensional feature construction step, this embodiment of the invention utilizes Volterra features to calculate the high-order polynomial features of the historical sequence (i.e., the concatenated multidimensional feature sequence). For the input historical sequence, a normalization operation is performed on each time point t in the sequence from 0 to h-1, such that... ,here and These represent the mean and standard deviation used for data normalization, respectively. Next, we will discuss the normalized series. Flattened into a vector For i from 1 to k, let This step involves calculating the Kronecker product, where... This represents the Kronecker product operation, where `i` indicates performing the Kronecker product `i` times. Ultimately, it returns the Volterra feature. It represents the tensorized interaction of past states from order 1 to order k.
[0066] Then, in the multi-channel linear transformation step, for the already calculated multidimensional features... Each channel k independently models the nonlinear interactions and memory effects of the system. A learnable discrete Wolterra coefficient matrix is set within each channel. To capture non-linear relationships.
[0067] Specifically, for the output of channel j The calculation process is as follows: ,in It is a constant term. It is a learnable coefficient matrix. This is a Volterra feature. After obtaining the output of each channel, a multi-channel linear transform layer is used to concatenate them together, and the output is projected back onto the original space: , ,in It is the number of channels. It is the dimension of the target time series. Indicates the first The output vectors of each channel at time t and , This represents the vector formed by concatenating the outputs of all channels at time t. and It consists of learnable weight matrices and biases.
[0068] Preferably, the multi-channel linear transformation layer uses polynomial approximation to provide a nonlinear representation of the latent function. Therefore, the method of the present invention does not depend on the activation function, does not require the design of a complex neural network structure, and only requires a simple linear layer to predict the coefficients of higher-order polynomials.
[0069] As preferred, the Volterra feature construction describes the matrix form polynomial expansion of the corresponding nonlinear dynamic system through the discrete Volterra coefficient matrix, thereby converting the nonlinear problem of time series analysis into a linear problem of learning polynomial coefficients, improving the model interpretability, and the multi-channel linear transformation provides a nonlinear representation for the potential function using polynomial approximation without activation function, and only through linear layer learning high-order polynomial coefficients.
[0070] As preferred, the popularity prediction effectively captures the complex spatio-temporal nonlinear interaction in the dynamic system by integrating high-order polynomials and time integration into the neural network, avoids the black box effect brought by traditional methods, improves the model interpretability, and facilitates user understanding of the working principle of the model.
[0071] On this structure, the present application calculates the discrete Volterra coefficient matrix through polynomial expansion, converts nonlinear time series modeling into linear polynomial coefficient learning, and then uses a multi-channel linear layer to predict the discrete Volterra coefficient matrix to obtain an accurate prediction of the topic popularity at the future time. Experimental results show that the method is effective. Through the prediction of the topic popularity, the present application can improve the dynamic understanding of the social network, help various organizations and individuals analyze the propagation trend of the topic in the social network, assist users in formulating a propagation strategy in advance, and optimize resource allocation.
