DETAILED DESCRIPTION OF THE EMBODIMENTS

[0048] Exemplary embodiments will be described in detail herein, and examples thereof are shown in the accompanying drawings. When the following description refers to the accompanying drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present invention as detailed in the appended claims.

[0049] Embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0050] As Figure 1 shown, an embodiment of the present invention provides a communication performance analysis method based on spatio-temporal-frequency resources, including:

[0051] S1. Obtain the types of spatio-temporal-frequency resources and communication performance analysis metrics input by staff, and generate a communication performance analysis test task according to the types of spatio-temporal-frequency resources and communication performance analysis metrics;

[0052] Spatio-temporal-frequency resources refer to the concept of effectively managing and utilizing time, space, and frequency resources in communication and network technologies. These resources are the core components of wireless communication and networks, especially in 5G, 6G, and future communication technologies. Spatio-temporal-frequency resources often have an impact on communication performance. Therefore, after determining the type of spatio-temporal-frequency resources input by the staff, communication performance analysis and test tasks can be generated based on the value range of the type of spatio-temporal-frequency resources, so as to obtain the actual values of communication performance analysis indicators.

[0053] S2. Execute the communication performance analysis and test tasks to execute the sample values corresponding to the spatio-temporal-frequency resource type, so as to obtain the actual values corresponding to the communication performance analysis indicators;

[0054] The communication performance analysis and test tasks can be combined test tasks of multiple spatio-temporal-frequency resources. These spatio-temporal-frequency resources can be applied to the communication system, and then the actual values corresponding to the communication performance analysis indicators can be obtained. By analyzing and learning these data, the impact of spatio-temporal-frequency resources on communication performance can be determined.

[0055] S3. Use an artificial intelligence model to construct a communication performance analysis model, and use the sample values of the spatio-temporal-frequency resource type as the input and the actual values of the corresponding communication performance analysis indicators as the expected output to optimize the communication performance analysis model, and obtain the optimized communication performance analysis model;

[0056] The artificial intelligence model is the core component in the field of artificial intelligence (AI). It refers to a collection of a series of algorithms and mathematical models. Therefore, in the embodiments of the present invention, an artificial intelligence model is used to construct a communication performance analysis model, and the relationship between the sample values of the spatio-temporal-frequency resource type and the actual values of the communication performance analysis indicators can be learned through artificial intelligence.

[0057] S4. Collect the allocation values corresponding to the spatio-temporal-frequency resource type, and use the optimized communication performance analysis model to identify the allocation values corresponding to the spatio-temporal-frequency resource type to obtain the communication performance analysis result.

[0058] After the communication performance analysis model is optimized, it has the ability to identify the allocation values corresponding to the spatio-temporal-frequency resource type. Therefore, after the staff formulates the allocation plan of the spatio-temporal-frequency resources, they can pre-analyze the communication performance corresponding to the allocation plan of the spatio-temporal-frequency resources, which is convenient for the staff to optimize the allocation plan of the spatio-temporal-frequency resources.

[0059] A communication performance analysis method based on spatio-temporal-frequency resources provided by the present invention collects spatio-temporal-frequency resource types and communication performance analysis metrics, and then generates a communication performance analysis test task according to the spatio-temporal-frequency resource types and communication performance analysis metrics. After executing the communication performance analysis test task, the relationship between the actual values of the spatio-temporal-frequency resource types and the actual values of the communication performance analysis metrics can be learned through artificial intelligence, so that in the subsequent process, the communication performance analysis metrics can be predictively analyzed through the actual values of the spatio-temporal-frequency resource types, enabling staff to quickly adjust the allocation of spatio-temporal-frequency resources according to requirements.

[0060] In an embodiment of the present invention, obtaining the spatio-temporal-frequency resource types and communication performance analysis metrics input by a staff member, and generating a communication performance analysis test task according to the spatio-temporal-frequency resource types and communication performance analysis metrics includes:

[0061] Obtaining the spatio-temporal-frequency resource types input by a staff member; wherein each spatio-temporal-frequency resource type has its corresponding upper limit and lower limit;

[0062] For example: The spatio-temporal-frequency resources can be transmission rate, beam scheduling, time allocation, etc. For any communication system, the spatio-temporal-frequency resources have corresponding upper and lower limits. If the spatio-temporal-frequency resources are certain fixed options, then the numerical division points of this spatio-temporal-frequency resource are those fixed options. For example, if the spatio-temporal-frequency resources are of types A1, A2, and A3, then the numerical division points are A1, A2, and A3.

[0063] Based on the fact that each spatio-temporal-frequency resource type has its corresponding upper limit and lower limit, the numerical interval corresponding to the spatio-temporal-frequency resource type is divided into a fixed number of parts by an equal division method to obtain multiple numerical division points corresponding to each spatio-temporal-frequency resource type (for example, if the transmission rate interval is (B, C), then (B, C) can be equally divided into N sub-intervals, and each boundary is a numerical division point);

[0064] Arranging and combining the multiple numerical division points corresponding to all spatio-temporal-frequency resource types to obtain sample values corresponding to multiple spatio-temporal-frequency resource types;

[0065] Generating a task to be executed for each sample value corresponding to a spatio-temporal-frequency resource type.

[0066] For example, if the numerical division points of the spatio-temporal-frequency resource A are a1 and a2, and the numerical division points of the spatio-temporal-frequency resource B are b1, b2, and b3, then the sample values corresponding to the spatio-temporal-frequency resource types can be (a1, b1), (a1, b2), (a1, b3), (a2, b1), (a2, b2), and (a2, b3). Any one of the sample values can be input into the communication system to obtain the actual value of the corresponding communication performance analysis index, so as to obtain the sample data for optimizing the artificial intelligence model.

[0067] In the embodiment of the present invention, performing the communication performance analysis test task to execute the sample value corresponding to the spatio-temporal-frequency resource type, so as to obtain the actual value corresponding to the communication performance analysis index, includes:

[0069] In the embodiment of the present invention, an artificial intelligence model is used to construct a communication performance analysis model, including: using a CNN (Convolutional Neural Network) model to construct a communication performance analysis model. It should be noted that other artificial intelligence models can also be used to construct a communication performance analysis model.

[0070] In the embodiment of the present invention, using the sample value of the spatio-temporal-frequency resource type as the input and the actual value of the corresponding communication performance analysis index as the expected output, the communication performance analysis model is optimized to obtain the optimized communication performance analysis model, including:

[0071] For the hyperparameters of the communication performance analysis model, the hyperparameters are initialized, and the initialized hyperparameters are encoded as vectors to obtain hyperparameter vectors. At the same time, multiple different hyperparameter vectors are obtained;

[0072] For example, the hyperparameters of the communication performance analysis model generally have upper and lower limits, and can be randomly initialized between the upper and lower limits, so as to obtain a hyperparameter vector.

[0073] For any one of the hyperparameter vectors, using the sample value of the spatio-temporal-frequency resource type as the input and the actual value of the corresponding communication performance analysis index as the expected output, the loss function value corresponding to the hyperparameter vector is obtained; for example: the root mean square error function value or the cross-entropy error function value can be obtained;

[0074] According to the loss function values corresponding to all the hyperparameter vectors, the optimal hyperparameter vector is determined;

[0075] For any hyperparameter vector, based on the optimal hyperparameter vector, perform a first local search on the hyperparameter vector using a local personalized search strategy to obtain the hyperparameter vector after the first local search;

[0076] For any hyperparameter vector after the first local search, based on the optimal hyperparameter vector, perform a second local search on the hyperparameter vector using a non - linear local search strategy to obtain the hyperparameter vector after the second local search;

[0077] For the hyperparameter vector after the second local search, perform a first global search on the hyperparameter vector using a reverse global greedy search strategy to obtain the hyperparameter vector after the first global search;

[0078] For the hyperparameter vector after the first global search, perform a second global search on the hyperparameter vector using a random global greedy search strategy to obtain the hyperparameter vector after the second global search;

[0079] Determine whether the optimization end condition is satisfied. If so, based on the hyperparameter vector after the second global search, re - obtain the optimal hyperparameter vector, and apply the parameters in the optimal hyperparameter vector to the communication performance analysis model to obtain the optimized communication performance analysis model. Otherwise, return to the step of obtaining the loss function value.

[0080] In the prior art, the gradient descent algorithm is often used to optimize the hyperparameters of the artificial intelligence model, and there are often technical problems such as being easily trapped in local optima. Therefore, the embodiments of the present invention provide an intelligent optimization algorithm to solve the technical problems existing in the prior art and improve the prediction ability of communication performance.

[0081] In the embodiments of the present invention, for any hyperparameter vector, based on the optimal hyperparameter vector, perform a first local search on the hyperparameter vector using a local personalized search strategy to obtain the hyperparameter vector after the first local search, including:

[0082] Based on the current number of optimizations, generate an adaptively decreasing weight control factor as: where ω represents the weight control factor, π represents pi, sin represents the sine function, T represents the maximum number of optimizations, and t represents the current number of optimizations;

[0085] According to the optimal information search term and the comprehensive information search term, perform a first local search on the hyperparameter vectors, and the hyperparameter vectors after the first local search are: Among them, Represents the hyperparameter vector after the first local search

At the same time, learning towards the optimal hyperparameter vector can effectively improve the convergence speed of the algorithm. In the later stage of the algorithm, the weight control factor decreases non-linearly, which can gradually improve the convergence accuracy of the algorithm.

[0087] In the embodiments of the present invention, for any hyperparameter vector after the first local search, according to the optimal hyperparameter vector, a second local search is performed on the hyperparameter vector using a non-linear local search strategy to obtain the hyperparameter vector after the second local search, including:

[0088] For any hyperparameter vector after the first local search, obtain the cosine information search term between the hyperparameter vector and the optimal hyperparameter vector as: Among them, r 4 Represents a random number between (0, 1), r 5 Represents a random number between (0, 1), Represents the jth hyperparameter vector after the first local search, j = 1, 2,..., I;

[0089] According to the cosine information search term and the weight control factor, perform a second local search on the hyperparameter vector, and the hyperparameter vector after the second local search is: Among them, Represents the hyperparameter vector after the second local search

[0090] The non - linear local search strategy provided by the embodiments of the present invention can enable all hyperparameter vectors to perform non - linear search around the optimal position, effectively improving the convergence speed and convergence accuracy of the algorithm.

[0091] In the embodiments of the present invention, for the hyperparameter vector after the second local search, a reverse global greedy search strategy is adopted to perform the first global search on the hyperparameter vector, and the hyperparameter vector after the first global search is obtained, including:

[0092] Based on the current number of optimizations, the non - linear perturbation factor is obtained as: where δ represents the non - linear perturbation factor, and T represents the preset maximum number of optimizations;

[0093] And for the hyperparameter vector after the second local search, the non - linear perturbation factor is used to perturb the hyperparameter vector to generate a perturbation information vector as: where represents the hyperparameter vector after the n - th second local search in the t - th optimization process, n = 1, 2, …, I, represents the perturbation information vector;

[0094] A reference information vector is generated according to the non - linear perturbation factor, and the hyperparameter vector is globally searched according to the reference information vector and the perturbation information vector to obtain the first global search vector as: where r 6 represents a random number between (0, 1), lb represents the upper - bound vector corresponding to the hyperparameter vector, ub represents the lower - bound vector corresponding to the hyperparameter vector, represents the first global search vector;

[0095] It is judged whether the loss function value of the first global search vector decreases. If so, the first global search vector is used as the hyperparameter vector after the first global search; otherwise, the original hyperparameter vector after the second local search is directly used as the hyperparameter vector after the first global search.

[0096] The reverse global greedy search strategy provided by the embodiments of the present invention can perform reverse search on each hyperparameter vector, thereby improving the search efficiency of the unknown region, effectively improving the traversability of the solution space, and thus avoiding falling into local optimality.

[0097] In the embodiments of the present invention, for the hyperparameter vector after the first global search, a random global greedy search strategy is adopted to perform the second global search on the hyperparameter vector, and the hyperparameter vector after the second global search is obtained, including:

[0098] For the hyperparameter vector after the first global search, according to the optimal hyperparameter vector, a random flight individual is generated for the hyperparameter vector as: Among them, represents a randomly flying individual, represents except random individuals outside, represents the hyperparameter vector after the m-th first global search in the t-th optimization process, m = 1, 2, …, I, α represents the random flight coefficient, u represents the first normal distribution random number, v represents the second normal distribution random number, and β represents the constant term;

[0099] According to the randomly flying individual corresponding to the hyperparameter vector, the cosine function is used to perform the second global search on the hyperparameter vector, and the second global search vector is obtained as: Among them, represents the second global search vector, r 7 represents a random number between (0, 1), r 8 represents a random number between (0, 1), and π represents the circumference ratio;

[0100] Judge whether the loss function value of the second global search vector decreases. If so, use the second global search vector as the hyperparameter vector after the second global search. Otherwise, directly use the hyperparameter vector after the original first global search as the hyperparameter vector after the second global search.

[0101] The second global search provided by the embodiments of the present invention can enable the algorithm to effectively jump out of the local optimal solution and provide strong global search capabilities, thereby improving the hyperparameter search ability.

[0102] Optionally, after each search for the hyperparameter vector, the hyperparameter vector can be processed to prevent it from exceeding the boundary, thereby ensuring the effectiveness of the algorithm.

[0103] In the embodiments of the present invention, determining whether the optimization end condition is satisfied includes:

[0104] Judge whether the current number of optimization times is greater than or equal to the maximum number of optimization times. If so, it is determined that the optimization end condition is satisfied. Otherwise, it is determined that the optimization end condition is not satisfied.
