Problems solved by technology

At present, most of them use a fixed model or a multiple linear regression to fit the prediction, resulting in a large deviation between the predicted perception and the actual perception
In addition, some scholars use GA (Genetic Algorithm, Genetic Algorithm) to construct complex fitting functions, but the algorithm's crossover mutation strategy is weak in ensuring solution diversity, and has inherent defects such as precocity and low efficiency.

Embodiment 1

[0071] The present invention provides a user perception evaluation method based on BSA algorithm, such as figure 1 As shown, it includes two parts: building a comprehensive user perception evaluation variable model and solving the KQI-QoE relationship prediction model based on the BSA algorithm.

[0072] In step 201, a comprehensive user perception evaluation model is constructed. Generally, the service to be evaluated includes multiple performances, and each performance corresponds to a set of KQI indicators and a sub-item user perception. Such as figure 2 As shown, the impact of perception evaluation is bottom-up, the better the perception of sub-items, the better the overall perception. Therefore, the comprehensive user perception can be expressed as follows:

[0073]

[0074]

[0075] Among them, QoE t Indicates the perception of the tth sub-item; λ t Represents the weight of the t-th sub-item perception; T represents the number of sub-items it contains, and f ...

Embodiment 2

[0085] The embodiment of the present invention is based on the technical content of the first embodiment, and the implementation process of the present invention is described in combination with specific scenarios. Solve the KQI-QoE optimal relationship prediction model based on BSA, such as Figure 4 As shown, the specific steps are as follows:

[0086] In step 301, the encoding mode and model constraints of the KQI-QoE prediction model are determined.

[0087] For example, if Figure 4 As shown, the system uses the binary tree encoding method to encode the sub-item prediction model, and the binary tree meets the following model constraints: (1) the binary tree meets the maximum depth constraint; (2) the binary tree is composed of operators, independent variables, and constants; (3) the binary tree The selection range of each node element is an operator, an independent variable or a constant; (4) The root node and intermediate node of the binary tree must be an operator, an...

Description

technical field [0001] The invention belongs to the technical field of communications, and more specifically relates to a method for evaluating user perception based on a backtracking search algorithm and electronic equipment. Background technique [0002] There are usually two methods of user perception measurement, one is to actually investigate the user's application experience quality, and the other is to infer the application's user experience quality by analyzing business indicators. The two methods of actual investigation and analysis of business indicators are not enough to obtain user perception in real time and intuitively. At present, with the wide application of communication technology and IoT platform, various services and applications urgently need to improve their users' application experience based on a large amount of high-quality and useful data collected and stored. Due to the diversity of users, actual scenarios, and performance parameters, solving the ...
