[0024] The embodiments of the present invention provide a method and device for health assessment of prebaked anode production equipment based on artificial intelligence, which can improve the intelligence level of the health management system of prebaked anode production equipment and achieve more efficient fault prediction and prevention.

[0025] For ease of understanding, a health assessment method for prebaked anode production equipment based on artificial intelligence provided by an embodiment of the present invention is first described. Figure 1 A flowchart of a method for health assessment of prebaked anode production equipment based on artificial intelligence provided by an embodiment of the present invention is shown. Figure 1 As shown, the method comprises the following steps: Step S102, obtaining monitoring data of prebaked anode production equipment.

[0026] The data collected in the present invention is the monitoring data of the prebaked anode production equipment, including the belt conveyor, vibrating screen and demoulding machine used in the prebaked anode production. Their stable operation is directly related to the production efficiency and product quality. Monitoring the operating status of these equipment is very important for preventing failures and optimizing the process flow. Among them, the collected data is stored in a structured JSON format. In one embodiment, the attributes of the data include: is the device operating speed, is the temperature index, is the vibration frequency, is the noise level, is the current intensity, is the voltage level, For routine maintenance times, is the number of failures, is the material type, is the ambient humidity.

[0027] It should be noted that this embodiment is only used to illustrate a data format and type of the present invention. In actual applications, the attributes of data are usually more than 10 attributes, and the number of attributes of data may reach dozens or even hundreds. In the embodiment of the present invention, the monitoring attributes also involve more dimensions of the equipment, such as the specific frequency spectrum of equipment vibration, energy efficiency, emission quality, etc. The embodiment of the present invention collects the above-mentioned types of data of the equipment to identify equipment anomalies, predict failures, and optimize production processes.

[0028] Step S104, input the monitoring data into a preset neural network, determine the neural network weights corresponding to the monitoring data, and use fuzzy logic to adjust the neural network weights.

[0029] Step S106, extracting target parameters of the monitoring data based on the adjusted neural network weights.

[0030] After acquiring the monitoring data, a pre-trained neural network model is used to extract features. In an embodiment of the present invention, the weights corresponding to the monitoring data are determined by a neural network model based on historical monitoring data to understand the characteristics of the input data. Furthermore, an embodiment of the present invention uses fuzzy logic to introduce rule-based decision-making capabilities for weight adjustment to extract target parameters from monitoring data, which can improve the robustness of the model in the face of uncertain data. Among them, the target parameters are indicators directly related to the health of the equipment, such as potential fault signals, degree of performance degradation, etc.

[0031] Step S108, input the target parameters into a pre-trained extreme learning machine, calculate the output layer weights of the extreme learning machine using a single-step learning algorithm, and output the prediction results corresponding to the target parameters based on the output layer weights.

[0032] Step S110, determining the health status of the prebaked anode production equipment based on the prediction result.

[0033] For the extracted target parameters, the embodiment of the present invention uses an extreme learning machine for classification prediction. The advantage of the extreme learning machine is its fast learning speed, which is suitable for real-time or near real-time prediction. In actual operation, the embodiment of the present invention uses a pre-trained extreme learning machine model that is fine-tuned for the application scenario to process the target parameters output from the neural network.

[0034] Among them, the single-step learning algorithm is a machine learning method that allows the model to be updated immediately after receiving each new sample, and is adapted to scenarios where data streams are constantly changing or memory resources are limited. Based on this, it is possible to adapt to dynamic changes in data and output prediction results that are adapted to current data. Finally, based on the prediction results, the health status of the device is judged by the set thresholds or classification rules. For example, if the prediction results show that certain key indicators deviate from the normal range, it can be determined that the device may have health risks or is about to fail. Specifically, the prediction results of an embodiment of the present invention include various health levels of the device, specifically: healthy, sub-healthy, mildly abnormal, severely abnormal, and faulty, 5 categories.

[0035] Furthermore, based on the above embodiment, the embodiment of the present invention also provides another artificial intelligence-based health assessment method for prebaked anode production equipment. Figure 2 A flowchart of another artificial intelligence-based prebaked anode production equipment health assessment method provided by an embodiment of the present invention is shown, referring to Figure 2 , the method comprises the following steps: Step S202, obtaining monitoring data of prebaked anode production equipment.

[0036] Step S204, forward propagating the monitoring data through a preset neural network to obtain a neural network output.

[0037] The present invention uses a 6-layer fully connected neural network for feature extraction. Among them, by extracting a batch of data from the data, forward propagation is performed through the neural network, and the output of each layer will be used as the input of the next layer until the last layer, and the neural network output is obtained. The process of forward propagation is expressed as:

[0038] In the formula, is the Sigmoid activation function; The neural network is The input data of the layer; The neural network is The output of the layer.

[0039] In the prior art, some solutions use neural networks for feature extraction. In some neural network structures, gradient vanishing, gradient exploding, or falling into local optimal solutions may occur, affecting the stability of training and the performance of the model. The present invention uses a neural network algorithm based on feature weight learning for feature extraction. By adopting a dynamic weight adjustment mechanism, the neural network can automatically adjust its weight according to the contribution of different features, and use fuzzy logic to evaluate the importance of each feature to the final prediction task, thereby improving the accuracy of feature extraction. Specifically, refer to the following steps S206-S210.

[0040] Step S206, based on the classification error corresponding to the neural network output and a preset feature importance threshold, fuzzy logic is used to determine the weight adjustment factor corresponding to the neural network output.

[0041] Step S208, adjusting the initial neural network weights of the neural network based on the weight adjustment factor to obtain adjusted neural network weights.

[0042] In the process of forward propagation, the embodiment of the present invention dynamically adjusts the weights of each layer according to fuzzy logic. Specifically, the weights are adjusted according to the influence of each feature on the output target, so that more influential features obtain higher weights. The adjustment method is expressed as:

[0043]

[0044] In the formula, is to adjust the sensitivity, is the feature importance threshold, The neural network The fuzzy logic weight adjustment factor for the layer. is the first neural network after updating according to fuzzy logic The weight of the layer; According to the neural network The output of the layer is classified using the preset Softmax classification function. Preferably, Set to 2.

[0045] Step S210, extracting target parameters of the monitoring data based on the adjusted neural network weights.

[0046] The neural network of the embodiment of the present invention is obtained by pre-training the training sample set. In the specific implementation, the training sample set is learned by the neural network, and the dynamic adjustment factor is determined based on the performance of the model and the influence of the data, so as to update the parameters of the neural network to improve the robustness of the model when facing uncertain data.

[0047] Specifically, the performance of the current model is measured using the loss function of the neural network. In one embodiment, the loss function is calculated as follows:

[0048] In the formula, is the loss function of the neural network, It is The true labels of samples, It is The predicted output of each sample is calculated by the output of the neural network through the preset Softmax classification function. is the number of samples input to the neural network in the current batch, is the regularization term of the neural network loss function.

[0049] In an embodiment of the present invention, the method of initializing the parameters of the neural network is expressed as:

[0050]

[0051] In the formula, It means the mean is 0 and the variance is Normal distribution of The neural network The weight of the layer; The neural network Preferably, Set to 0.01.

[0052] It can be seen from the above loss function that the loss function of the embodiment of the present invention is combined with a regularization term. In combination with the embodiment of the present invention, the weight of the neural network is adjusted by calculating the weight adjustment factor. When training the neural network, the embodiment of the present invention adopts an adaptive fuzzy dynamic regularization method, and the real-time feedback obtained is dynamically adjusted to define the dynamic regularization term. The calculation method of the regularization term of the neural network loss function is expressed as:

[0053] In the formula, is the weight The square of the L2 norm of represents the L2 norm, It is a dynamic adjustment factor obtained based on fuzzy logic.

[0054] Furthermore, the calculation method of the dynamic adjustment factor obtained according to fuzzy logic is expressed as:

[0055] here, is the sensitivity parameter of fuzzy logic, is the feature importance threshold. Preferably, Set to 0.3, Set to 2.

[0056] Back propagation of errors and parameter updates are performed based on the loss function to ensure that each parameter update is in the direction of reducing the total loss. Specifically, the calculation method for the update amount of the neural network weights and biases is expressed as:

[0057]

[0058] In the formula, is the update amount of the neural network weight parameters, is the update amount of the neural network bias parameter, is the learning rate of the neural network, is the symbol of partial derivative.

[0059] Repeat the above steps until the preset stop iteration condition is met, which means that the model training is completed. In one embodiment, the preset stop iteration condition is reaching a preset maximum number of iterations. Preferably, the preset maximum number of iterations is set to 1000 times.

[0060] In summary, the embodiment of the present invention determines the weight adjustment factor based on the importance threshold of the feature, thereby updating the weight of the neural network used to extract the target parameters in the monitoring data based on the weight. At the same time, the neural network used in the embodiment of the present invention adjusts the neural network parameters based on the above-mentioned weight adjustment factor according to the degree of influence of each feature on the output target during the training process, so that the neural network can adapt to the data during the training stage and improve the robustness of the model when facing uncertain data. In summary, the feature extraction of the embodiment of the present invention adopts a fully connected neural network based on feature weight learning. Through a dynamic weight adjustment mechanism, the weight is automatically adjusted according to the degree of influence of each feature on the output target (that is, the importance of the feature), so that more influential features obtain higher weights, effectively deal with the problem of gradient disappearance or explosion, and enhance the model's learning ability for important features. Feature weight learning enables the neural network model to more accurately identify and strengthen the learning of key features, thereby improving the accuracy of feature extraction and the overall effectiveness of the model.

[0061] Furthermore, in high-dimensional data processing, the current feature dimensionality reduction technology fails to accurately distinguish and retain the most critical features, affecting the efficiency and accuracy of the model in complex data analysis. In this regard, the embodiment of the present invention also performs dimensionality reduction processing on the target parameters through an autoencoder. Among them, the hidden layer of the autoencoder uses a sparse regularization strategy to activate some neurons of the autoencoder, and the activation state of the neurons is determined based on the dynamic threshold of the target parameter.

[0062] In the specific implementation, the present invention adopts an autoencoder neural network algorithm based on transform domain sparse representation as a feature dimensionality reduction model. On the basis of the autoencoder algorithm, the hidden layer of the autoencoder adopts a sparse regularization term constraint to only promote the sparse representation of features in the hidden layer, thereby enhancing the model's ability to capture important features in the input data.

[0063] Specifically, the steps for reducing the dimension of the target parameters are as follows: 1) The input feature-extracted data is processed by the encoder part, where the output of each layer is a function of the output of the previous layer and the parameters of the current layer. Specifically, during the training process, the forward propagation process of the data in the autoencoder is expressed as:

[0064] In the formula, is the ReLU activation function, It is the autoencoder The output of the layer, It is the autoencoder The output of the layer.

[0065] The parameters of the autoencoder include the weight and bias of the autoencoder. In one embodiment, the initialization method of the parameters of the autoencoder is expressed as follows:

[0066]

[0067] In the formula, For the autoencoder The weight of the layer, For the autoencoder Bias of the layer; It means the mean is 0 and the variance is Normal distribution of Indicates that in [- , ] is uniformly distributed within the interval. Preferably, Set to 0.1, Set to 0.1.

[0068] 2) In the hidden layer, a sparse regularization strategy is used to force a small number of neurons to be activated, ensuring that only the most important features are retained. Specifically, the activation state of the hidden layer neurons is controlled by a dynamic threshold that depends on the data, expressed as:

[0069] In the formula, is the sparse regularization function; is the output of the hidden layer of the autoencoder; is the regularization strength, which is used to control the degree of sparsity. In the embodiment of the present invention, the regularization strength is set manually; It is the autoencoder The output of the layer.

[0070] Furthermore, the calculated sparse regularization function value is used as a dynamic threshold to determine the activation state of the hidden layer neurons. For example, if the calculated sparse regularization function value is greater than 0.5, 10 neurons are randomly inactivated; if the calculated sparse regularization function value is less than or equal to 0.5 and greater than 0.3, 20 neurons are randomly inactivated; if the calculated sparse regularization function value is less than or equal to 0.3, 30 neurons are randomly inactivated.

[0071] 3) The encoded features are then sent to the decoder for decoding and reconstruction. The task of the decoder is to reconstruct the original input data as much as possible using the encoded data, expressed as:

[0072] In the formula, is the decoder reconstructed input; is the decoder weight, is the decoder bias.

[0073] Specifically, the autoencoder used in the embodiment of the present invention is pre-trained, wherein the responsiveness of the model to changes in input data is enhanced by adopting dynamic weight adjustment. In the specific implementation, the parameter gradient of the autoencoder is calculated; and, based on the weight vectors of all layers of the autoencoder, the adjustment vector corresponding to the target parameter is calculated; based on the gradient descent of the parameter gradient and the adjustment vector, the weight and bias of the autoencoder are updated.

[0074] In the specific implementation, the above steps are used to perform data encoding and decoding operations through the training sample set to perform model training. Furthermore, the loss function of the autoencoder is calculated based on the reconstruction error and the sparse regularization term to find the best balance between the reconstruction accuracy and the sparsity of feature extraction. The calculation method of the loss function of the autoencoder is expressed as:

[0075] In the formula, is the loss function of the autoencoder, is the regularization term weight of the autoencoder loss function. Preferably, Set to 0.3.

[0076] Furthermore, based on the calculated loss, the back propagation algorithm is used to calculate the gradient of each parameter, and the weights and biases of the autoencoder are updated using gradient descent. The update method is expressed as:

[0077]

[0078] In the formula, is the learning rate of the autoencoder; is the updated autoencoder The weight of the layer; is the updated autoencoder Bias of the layer; represents element-wise multiplication; is the dynamic weight adjustment factor, whose elements are , Indicates that it is used for The adjustment vector of the features.

[0079] In one embodiment, dynamic weight adjustment is used to enhance the responsiveness of the model to changes in input data. Specifically, the dynamic weight adjustment factor is dynamically calculated based on the characteristics of the input data and is expressed as:

[0080] In the formula, is the Sigmoid activation function, Indicates that it is used for The adjustment vector of the feature is obtained by taking the average of the weight vectors of all layers of the autoencoder; is a bias term used to adjust the dynamic adjustment factor.

[0081] Further, the above steps are repeated until the preset stop iteration condition is met, indicating that the model training is completed. In one embodiment, the preset stop iteration condition is reaching a preset maximum number of iterations, preferably, the preset maximum number of iterations is set to 1000 times.

[0082] The feature dimensionality reduction model of the embodiment of the present invention uses an autoencoder based on transform domain sparse representation, and retains only the most important features through a sparse regularization strategy, aiming to improve the data processing efficiency and anti-interference ability of the model. The use of an autoencoder based on transform domain sparse representation for feature dimensionality reduction enhances the model's ability to capture important features in the input data, while improving the speed and stability of data processing.

[0083] Step S212, input the target parameters into a pre-trained extreme learning machine, calculate the output layer weights of the extreme learning machine using a single-step learning algorithm, and output the prediction results corresponding to the target parameters based on the output layer weights.

[0084] In specific implementation, the embodiment of the present invention obtains the hidden layer output matrix of the extreme learning machine; performs matrix identity calculation on the hidden layer output matrix to determine the output layer weight of the extreme learning machine, thereby determining the prediction result of the target parameter. Among them, the embodiment of the present invention adopts the extreme learning machine algorithm based on matrix identity as the classifier model, and uses the gradient control mechanism to dynamically adjust the learning rate and weight update strategy during the training process to improve the classification accuracy.

[0085] Specifically, the steps to determine the output layer weights are as follows: 1) Input the data into the hidden layer of the extreme learning machine. The data is expressed as follows through nonlinear transformation of the hidden layer:

[0086] In the formula, is the output feature of the hidden layer of the extreme learning machine; is the Sigmoid activation function; It is the data output from the feature dimensionality reduction model as the input of the extreme learning machine.

[0087] The method of initializing the weights and biases of the extreme learning machine used in the embodiment of the present invention is expressed as follows:

[0088]

[0089] In the formula, is the weight of the extreme learning machine, is the bias of the extreme learning machine; It means the mean is 0 and the variance is Normal distribution of Indicated in Uniform distribution within the interval; The preset parameters for initializing the weights of the extreme learning machine, is the preset parameter for initializing the bias of the extreme learning machine. Preferably, Set to 0.1, Set to 0.2.

[0090] 2) Use the single-step learning algorithm to calculate the output layer weights.

[0091] Specifically, a linear or nonlinear transformation is applied to the hidden layer output to match the expected output. The calculation method of the output layer weight is expressed as:

[0106] In an embodiment of the present invention, the prediction result includes one of the following health levels: healthy, sub-healthy, mild abnormality, severe abnormality, and failure; the embodiment of the present invention determines the health level in the prediction result as the health status level of the prebaked anode production equipment.

[0107] Furthermore, the embodiment of the present invention also designs a training sample set. Correspondingly, the embodiment of the present invention also provides another artificial intelligence-based health assessment method for prebaked anode production equipment. Figure 3 A flowchart of the method for constructing a training sample set corresponding to this embodiment is shown. Figure 3 As shown, the method comprises the following steps: Step S10, obtaining equipment monitoring samples of prebaked anode production equipment.

[0108] Step S11, annotating data of equipment monitoring samples based on the equipment health status of the prebaked anode production equipment to construct an initial sample set.

[0109] The equipment monitoring samples refer to the monitoring data of the above embodiment, which will not be described here. The embodiment of the present invention constructs an initial sample set by annotating these data. The annotation method of the present invention is manual annotation. In one embodiment, the annotated categories include various health levels of the equipment, specifically: healthy, sub-healthy, mild abnormality, severe abnormality, and failure, 5 categories.

[0110] Step S12, converting the initial sample set into a quantum state, and based on the quantum state of the initial sample set, performing data expansion on the initial sample set to construct a training sample set.

[0111] It is understandable that in the task of the present invention, the collection, acquisition, labeling and preprocessing of training data are time-consuming and labor-intensive, and insufficient training samples can easily lead to poor model generalization ability and affect the accuracy of the model. Existing data enhancement strategies perform poorly in generating virtual samples that are highly matched with measured data, resulting in model training being constrained by a limited amount of real data, which in turn affects the model's ability to generalize to new scenarios.

[0112] In this regard, the present invention maps the data to the high-dimensional Hilbert space of the quantum state, and uses a generative adversarial network algorithm based on quantum computing to generate samples, thereby achieving data expansion. The embodiment of the present invention can realize complex nonlinear data transformation through quantum gate operations and enhance the expressiveness of the data. The generative adversarial network includes two parts: a quantum generator and a discriminator. The quantum generator uses quantum superposition and entanglement characteristics to generate high-dimensional feature data, and the discriminator determines the consistency of the generated data with the real data.

[0113] Specifically, the embodiment of the present invention converts data into quantum state through the following steps: 1) Define the quantum state conversion function; 2) The initial sample set is operated through a generative adversarial network, and the angular parameters of the Bloch sphere of the quantum bit are determined based on the weight matrix and bias term of the generative adversarial network.

[0114] 3) Determine the state of a single quantum bit based on the angle parameter; 4) Based on the state of the quantum bit, the initial sample set is mapped to the quantum state through the quantum state conversion function.

[0115] Among them, the collected monitoring data of the pre-baked anode production equipment is converted into a quantum state through quantum feature mapping, and each monitoring data point is encoded as a set of quantum gate operations of quantum bits. Specifically, the data mapping method is expressed as:

[0116] In the formula, is a quantum state conversion function, which converts the monitoring data of the prebaked anode production equipment into a quantum state; is the quantum state corresponding to the original monitoring data vector, is the original monitoring data vector.

[0117] In one embodiment, the quantum state conversion function is implemented as follows:

[0119] Furthermore, an embodiment of the present invention combines a generative adversarial network to perform data expansion. Correspondingly, based on the weights and biases of the generator of the generative adversarial network, two key angles of the state of a single quantum bit are described to determine the state of each quantum bit.

[0120] Specifically, the first parameter of the Bloch sphere of the quantum bit and the second parameter of the Bloch sphere of the quantum bit determine the state calculation method of each quantum bit, which is expressed as:

[0121]

[0122] In the formula, and is the weight matrix of the generator, and is the bias vector of the generator, is the Sigmoid activation function.

[0123] Furthermore, a generative adversarial network is used for data expansion, wherein an embodiment of the present invention calculates the Hamiltonian of the quantum state through Pauli-X operations and Pauli-Z operations of quantum bits, as well as identity operations; based on the Hamiltonian and quantum gate operations, the quantum state is expanded through a generative adversarial network.

[0124] The specific implementation includes the following steps: 1) The quantum generator of the generative adversarial network generates new quantum states based on the current quantum state by using a sequence of quantum gates. These quantum states represent the expanded feature data, expressed as:

[0125] In the formula, is the quantum gate operation function, is the quantum gate operation function of the iteration; The quantum state corresponding to the monitoring data vector generated by the generator; The number of samples entered for the current batch; Indicates The monitoring data samples are applied to the Hamiltonian of the quantum state, For the The Hamiltonian coefficients corresponding to the monitoring data samples.

[0126] Among them, the weights and bias parameters of the quantum generator and discriminator are initialized randomly, and the initialized parameters must obey a normal distribution with a mean of 0 and a variance of the unit matrix.

[0127] Referring to the above formula, it can be seen that the embodiment of the present invention not only uses the principles of quantum mechanics to enrich the data set and improve the performance of the machine learning model when processing data with complex structures and high correlations. It also combines the Hamiltonian of the quantum state for data expansion. The Hamiltonian is the sum of the energy of the quantum system and includes all possible energy interaction terms of the system to capture the core features of the data and potential interactions.

[0128] In one embodiment, The calculation of the Hamiltonian of the quantum state using a monitoring data sample adopts multiple operations to jointly determine the conversion process of the quantum state. The calculation method is expressed as:

[0129] In the formula, and They are Pauli-X and Pauli-Z operations on qubits, The embodiment of the present invention uses the principle of quantum mechanics to enrich the data set and improve the performance of the machine learning model when processing data with complex structures and high correlation.

[0130] 2) The discriminator evaluates the consistency between the data generated by the quantum generator and the actual monitoring data. The calculation method of its loss function is expressed as:

[0131] In the formula, is the loss function of the discriminator; The quantum state corresponding to the j-th monitoring data vector generated by the generator; is the label of the jth monitoring data, indicating whether the data is real data; is the inverse function of the quantum state conversion function; is the discriminator function.

[0132] In one embodiment, the inverse function of the quantum state conversion function maps the quantum state back to traditional data, expressed as:

[0133]

[0134]

[0135]

[0136] In the formula, is the vector that maps back from the quantum state to traditional data; For quantum state The status value of is the first Pauli matrix, is the second Pauli matrix, is a third Pauli matrix, wherein the first Pauli matrix, the second Pauli matrix and the third Pauli matrix are used to extract data mapped back to the traditional feature space from the quantum state; To take the real part operation, To take the imaginary part operation; represents the inner product; Indicates the absolute value operation.

[0137] The generator and discriminator of the generative adversarial network of the embodiment of the present invention are subjected to data expansion after training. Corresponding to the above steps, during the training process, the embodiment of the present invention adjusts the quantum gate parameters of the quantum generator based on the feedback of the discriminator loss function to optimize the generation process of the quantum state. The adjustment method is expressed as:

[0138] In the formula, For the updated The Hamiltonian coefficient corresponding to the monitoring data sample is is the learning rate of the generative adversarial network, Represents the loss function with respect to parameter The partial derivative of is the parameter adjustment term of the Hamiltonian coefficient. Preferably, Set to 0.01.

[0139] Furthermore, the loss function is about parameter The calculation method of the partial derivative is expressed as:

[0140] In the formula, represents the right vector of the quantum state, Represents the left vector of the quantum state.

[0141] In one embodiment, the parameter adjustment item of the Hamiltonian coefficient is obtained by an adaptive feature optimization mechanism to enhance the capability of the quantum generator, and dynamically adjust the parameters of the quantum gate operation according to the evolution of the quantum state, thereby optimizing the feature representation of the generated data. Specifically, the adaptive adjustment mechanism adjusts the parameters of each operation based on the evolution entropy of the quantum state, thereby better controlling the flow of information and the representation of the feature, and defining an entropy metric to evaluate the degree of disorder of the quantum state, and the calculation method is expressed as:

[0142] In the formula, It is a quantum state The density matrix of represents trace operation; is the entropy measurement function.

[0143] Furthermore, based on the degree of disorder of the quantum state, the parameter adjustment term of the Hamiltonian coefficient is calculated as follows:

[0144] In the formula, is the learning rate of the Hamiltonian. Preferably, Set to 0.03.

[0145] Further, the above steps are repeated until the preset stop iteration condition is met, indicating that the model training is completed. In one embodiment, the preset stop iteration condition is reaching a preset maximum number of iterations, preferably, the preset maximum number of iterations is set to 1000 times.

[0146] In summary, another artificial intelligence-based health assessment method for prebaked anode production equipment provided by the embodiment of the present invention uses a quantum computing-based generative adversarial network for data expansion, and generates virtual data with high consistency with actual monitoring data through quantum state mapping and quantum gate operations, thereby solving the problem of insufficient training data.
