[0071] The present invention provides an emotion recognition method based on multimodal information fusion of fuzzy brain and hybrid experts. Through a deep feature extraction fusion model (network), the information of the network can flow effectively, giving full play to the advantages of multimodal and multi-layer features. It can reduce the complexity of the network structure, make full use of the connection between the modes, and give full play to the advantages of multimodal data.

[0072] Based on the above embodiments, in an optional embodiment of the present invention, as Figure 4As shown, the deep feature extraction fusion model includes a feature extraction network, a horizontal connection network and a feature splicing network.

[0073] The number of feature extraction networks is the same as the number of modalities in the initial data, and they are used to extract features from data of different modalities respectively. The feature extraction network includes a plurality of first feature extraction modules arranged in cascade, which are used to perform multi-level extraction of features. Preferably, the number of the first feature extraction modules is four. The first feature extraction module includes a two-dimensional convolutional layer, a LeakyRelu activation layer and a maximum pooling layer arranged in cascade. The convolution kernels of the two-dimensional convolutional layers of the four first feature extraction modules arranged in cascade are 16, 32, 64 and 128 respectively.

[0074] The number of the first feature extraction modules in the horizontal connection network and the feature extraction network is the same. A plurality of the horizontal connection networks are respectively connected to the first feature extraction modules at the same level of different feature extraction networks. The horizontal connection network includes a horizontal connection module and a second feature extraction module. The horizontal connection module is used to horizontally connect the features extracted by the first feature extraction module at the same level. The second feature extraction module is used to extract features from the features after horizontal connection to obtain horizontal connection features of each level. Preferably, the second feature extraction module includes a two-dimensional convolutional layer, an activation function layer, a maximum pooling layer, a two-dimensional convolutional layer, an activation function, a maximum pooling layer, a flattening layer, and a fully connected layer connected in sequence.

[0075] The feature splicing network is used to splice the horizontally connected features of each level into the fused feature. Preferably, the feature splicing network is configured to perform vertical splicing.

[0076] Specifically, the embodiment of the present invention proposes a deep feature extraction fusion model (network) designed for multimodal data (such as Figure 4 As shown in Figure 2, replacing the traditional feature extraction network (such as Figure 3 The model of first extraction and then fusion is used to explore the strategies and methods of combining complementary spatial information between multiple modalities with different attributes, so that the information of the network can flow effectively and give full play to the advantages of multimodal and multi-layer features. The model obtained by the study can not only reduce the complexity of the network structure, but also make full use of the connection between the various modalities, and give full play to the advantages of multimodal data.

[0077] like Figure 3As shown in the figure, in most current multimodal recognition studies, different models are used for feature extraction for each modality, and multiple top-level feature vectors are concatenated and fused at the end. Although this method is easy to implement, it does not establish the spatiotemporal correlation between the modalities during the feature extraction process, and it also fails to combine different shallow and deep semantic features. In many current multimodal application scenarios with high recognition complexity, this simple fusion solution has great limitations. When faced with the problem of high model complexity, it cannot fully utilize the advantages of multimodal data, and there is no close connection between the models, resulting in results that are insufficient to meet high-accuracy classification requirements.

[0078] To solve this problem, the present invention designs a deep neural network architecture (such as Figure 4 As shown in the figure, a hybrid network with multiple connections between layers is constructed, and each modality is integrated during the feature extraction process to cope with the high complexity of multimodal feature recognition and to help the recognition accuracy and adaptability of the recognition system.

[0079] Specifically, the embodiment of the present invention improves the traditional CNN feature extraction network and proposes a deep feature extraction fusion model (such as Figure 4 As shown in Figure 2). Compared with the traditional fusion method, the network architecture has made adjustments in the fusion method and fusion time. By building multiple CNN structure flows in one network, the function of simultaneously extracting features from multiple modal data is realized. At the same time, the model is scalable and can be applied to various modal data, and the model complexity will not increase significantly when the number of modalities increases.

[0080] like Figure 3 The existing model shown in FIG. 1 extracts features layer by layer through a convolutional neural network, and concatenates the feature vectors extracted by the two models at the end of the network. The two models have no intersection in the intermediate scale of feature extraction, while the deep feature extraction fusion model (such as Figure 4 (as shown) is to establish a connection between two branches during the extraction process, and fuse the outputs of the convolution blocks of corresponding scales. In the selection of the solution for multi-layer multimodal feature fusion, the embodiment of the present invention uses horizontal connections as mixed connections in different modal structure flows, and can obtain joint representations of multiple modalities at different scales. These fused features of different scales will be pushed into multiple feature extraction blocks again for further feature extraction. This method of fusing in multiple stages of feature extraction makes full use of the spatial information of different layers and establishes the correlation between different modalities.

[0081] According to the network architecture proposed above, the internal layer structure of the network is designed. The detailed structure of each layer of the proposed deep feature extraction fusion model and the second feature extraction module The internal structure is shown in the attached Figure 5 and Figure 6 As shown in the figure, each feature extraction network contains four convolution blocks, each of which consists of a two-dimensional convolution layer, a LeakyRelu activation layer, and a maximum pooling layer. However, as the number of network layers increases from shallow to deep, the number of convolution kernels in each convolution block changes, which are 16, 32, 64, and 128 respectively.

[0082] The network horizontally concatenates and fuses the outputs of convolution blocks of the same scale on different branches, and the fused feature vector is sent to the second feature extraction module again. Further extract features. It contains two convolutional layers, an activation function layer and a maximum pooling layer, and is flattened before being input into a fully connected layer. Output Said that eventually Vertical splicing is performed to obtain the final fused feature vector.

[0083] The embodiment of the present invention proposes to use the Gaussian interval type II fuzzy brain emotion learning model (network) as the expert model of the hybrid expert system to form a new hybrid expert system (such as Figure 7 As shown in the figure), the complementary nonlinear correlation of features is fully utilized, and by designing a suitable gating network and dynamically allocating expert model resources, the hybrid expert model can flexibly adapt to different input data distributions and task requirements, thereby improving the performance and efficiency of the model and enabling it to have better accuracy and adaptability when processing complex multimodal data.

[0084] On the basis of the above embodiment, in an optional embodiment of the present invention, the model of the interval type-2 fuzzy brain emotion learning network is: In the formula, is the output of the model of interval type-2 fuzzy brain emotion learning network, is the output of the amygdala network, is the output of the orbitofrontal cortex network.

[0085] In this embodiment, the interval type-2 fuzzy brain emotion learning network includes an input layer, an amygdala network, an orbitofrontal cortex network and an output layer.

[0086] The model of the amygdala network is: In the formula, is the output of the amygdala network, and are the output values ​​of the left and right points of the amygdala after fuzzy reasoning, Calculate the number of blocks in the amygdala network, is the output of the left point of the perception layer, is the output of the right point of the perception layer, The amygdala The linear weight of the computational blocks, and are the upper and lower bounds of the amygdala linear weight, respectively.

[0088] It is understood that a horizontal line above a symbol in a formula indicates an upper limit value of the symbol, and a horizontal line below a symbol in a formula indicates a lower limit value of the symbol.

[0089] The amygdala network includes a perception layer and an excitation layer.

[0090] Preferably, the model of the perception layer is: In the formula, For the Input features Located in the amygdala The membership of the computational blocks, and are the upper and lower bounds of the amygdala membership, is an exponential function with a natural constant as its base. For the Input features, is the variance of the interval type II Gaussian membership function in the amygdala network, is the initial mean of the interval type II Gaussian membership function in the amygdala network, , and They are the upper and lower bounds of the initial mean of the interval type-II Gaussian membership function in the amygdala network, respectively.

[0091] Preferably, the model of the excitation layer is: In the formula, is the upper bound of fuzzy reasoning, is the lower bound of fuzzy reasoning, is the number of input features.

[0092] The maximum weight matching point of the left brain calculated by the KM algorithm and the right brain maximum weight matching point , then according to the upper bound of fuzzy reasoning , the lower bound of fuzzy reasoning , the maximum weight matching point of the left brain and the right brain maximum weight matching point , get the output of the left point of the perception layer And the output of the right point of the perception layer . This algorithm can significantly improve the computational efficiency of the model.

Minimize The error of each network is negatively correlated with the error of the rest of the whole. This parameter is used to adjust the intensity of the penalty. When it is 0, there is no relevant penalty term in the error function of each network, and each network is trained independently. The purpose of this penalty function is to encourage different individual networks to learn different parts of the training data in order to better learn the entire training data.

[0097] In the study of brain emotion learning models, the definition of reward signal REW is one of the key points. This signal is flexible and needs to be determined according to the specific system type in order to achieve the optimal performance of the model. For example, when the network is applied to control systems, the reward signal is generally related to the control error, frequency deviation or other control signals, such as sliding mode control signals.

[0098] Similarly, for classification problems, it is also necessary to define a suitable reward signal. In order to make the interval type-2 fuzzy brain emotion learning network suitable for the learning strategy of the hybrid expert network, this patent develops an independent reward signal for the interval type-2 fuzzy brain emotion learning network model as a gated network. , whose mathematical meaning is the posterior probability that each expert can generate the desired output.

[0100] The main feature that distinguishes the brain emotion learning model from common intelligent algorithms is the special weight update rule. In the hybrid expert architecture, the expert network and the gated network usually use different weight update methods.

[0101] Based on the above embodiment, in an optional embodiment of the present invention, similar to the negative correlation learning method, the introduced penalty term provides a control parameter that can approach the optimal balance in the bias-variance-covariance trade-off. In the hybrid expert recognition model proposed in this embodiment, each expert is an interval type-2 fuzzy brain emotion learning network, and its weight is updated according to the following rules.

[0104] In the formula, is the weight of the hidden layer of the amygdala network in the expert model, for The update amount, is the momentum degradation rate, For the An expert model can generate an estimate of the posterior probability of the desired output, is the learning rate of the amygdala network in the expert model, For input features, is a function that takes the maximum value of two numbers, is the true label value, is the output of the amygdala network in the expert model, is the weight of the hidden layer of the orbitofrontal cortex network in the expert network, for The update amount, is the learning rate of the orbitofrontal cortex network in the expert network, For the The output of an expert model.

[0105] On the basis of the above embodiment, in an optional embodiment of the present invention, based on the error function of the gating network, the weight of the gating network is determined according to the following rules using the BP error algorithm.

[0106] .

[0107] .

[0108] In the formula, is the weight of the hidden layer of the amygdala network in the gating model, for The update amount, is the learning rate of the amygdala network in the gating model, As a reward signal, is the output of the amygdala network in the gating model, The gated network is the weight of the hidden layer of the orbitofrontal cortex network, for The update amount, is the learning rate of the orbitofrontal cortex network in the gating network, is the gate value.

[0109] In the traditional brain emotion learning network model, the calculation of sensory input is located in the sensory cortex, and the calculation results are sent directly to the orbitofrontal cortex and amygdala space. There is no learning process inside the sensory cortex.

[0110] On the basis of the above embodiment, in an optional embodiment of the present invention, after adding fuzzy logic, it is necessary to update the fuzzy parameters, ie, the mean and variance of the Gaussian function, which means that the sensory cortex needs to have a learning rule.

[0111] The embodiment of the present invention uses the following update formula to adjust the parameters in the Gaussian function:

[0123] The hybrid expert recognition model in the emotion recognition method based on multimodal information fusion of fuzzy brain and hybrid experts of the present invention is as follows: Figure 7 As shown in the figure. Its operation process can be summarized as follows: First, the fused multimodal features are received from the deep feature extraction fusion model (network). Then, the features are simultaneously input to the expert network and the gated network for training. During the training process, the expert classifiers compete with each other for different input features, and the gated network determines the proportion of each expert's decision in the final decision based on the judgment error of each expert classifier. As can be seen from the figure, in this system, each expert classifier processes the data in parallel, and increasing the number of expert classifiers does not affect the computational complexity of the model. Therefore, the number of expert classifiers can be appropriately adjusted according to actual needs.

[0124] In the feature fusion stage at the front end of the system, the embodiment of the present invention constructs an expandable advanced deep feature extraction framework to extract complementary spatial feature information from various modalities, and fully utilizes the advantages of multimodal data to alleviate the gradient vanishing problem that may occur when processing each modal data separately; in the decision-making stage at the end of the system, the reward signal of the brain emotion learning model is improved, and Gaussian interval type-2 fuzzy logic is added. It is used as an expert model in the hybrid expert network, and the nonlinear correlation between multimodal data is used to design an adaptive gating network, which greatly improves the accuracy and generalization of recognition, and provides new ideas and methods for the study of emotion recognition with multimodal information fusion.
