[0002] In today's society, with the rapid changes in lifestyle and the diversification of dietary structure, obesity has become an increasingly serious health challenge worldwide. According to the World Health Organization, more than 1.3 billion people are overweight, of which more than 65 million suffer from severe obesity. Obesity not only affects an individual's appearance and self-esteem, but more importantly, it is closely related to a variety of chronic diseases, such as cardiovascular disease, diabetes, hypertension, and certain types of cancer, which seriously threatens the quality of life and life expectancy of human beings.

[0003] In response to this challenge, fat reduction has become a health focus of the general public. However, traditional fat reduction methods often rely on individual self-management and simple dietary adjustments, lack scientificity and personalization, and are difficult to effectively respond to complex physiological changes and psychological needs.

[0055] The following is a non-restrictive description of the fat loss training management device based on big data provided according to at least one embodiment of the present application through several examples or embodiments. As described below, different features in these specific examples or embodiments can be combined with each other without conflicting with each other to obtain new examples or embodiments, and these new examples or embodiments also fall within the scope of protection of the present application.

[0056] In response to the above technical problems, the technical concept of this application is to use artificial intelligence technology based on deep learning to analyze the body composition data and fat-reducing training program of the monitored object, dig out the time-series dynamic change pattern of the body composition of the monitored object, and the deep semantic information of the fat-reducing training program, and then based on the semantic offset between the two, intelligently judge whether the fat-reducing training program needs to be adjusted. In this way, the blindness and inefficiency of traditional fat-reducing methods can be effectively avoided, and tailored fat-reducing training suggestions can be provided to the monitored object to ensure that the fat-reducing process is more scientific, accurate and efficient.

[0057] Based on this, this application proposes a fat loss training management device based on big data. Figure 1The structural schematic diagram of the fat-reducing training management device 800 based on big data in the embodiment of the present application is shown. The fat-reducing training management device 800 based on big data includes: a body fat scale data acquisition module 810, which is used to obtain the time series of body composition data of the monitored object, wherein the body composition data includes weight, body fat percentage, muscle mass, bone mass, water content, basal metabolic rate, visceral fat level, body age, protein content, body mass index and fat-free body weight; a fat-reducing training program setting module 820, which is used to receive the fat-reducing training program input by the user; a big data module 830, which is used to feature encode the time series of the body composition data and the fat-reducing training program to obtain the body composition time series associated aggregation feature and the fat-reducing training program semantic coding feature; a training management result generation module 840, which is used to determine the training management result based on the body composition time series associated aggregation feature and the fat-reducing training program semantic coding feature, and the training management result is used to indicate whether the fat-reducing training program needs to be adjusted.

[0058] Among them, Figure 2 As shown, the big data module 830 includes: a body composition data time series association analysis unit 831, which is used to perform time series association analysis on the time series of the body composition data to obtain a time series of body composition time series association implicit feature vectors; a body composition feature time series propagation aggregation unit 832, which is used to perform feature time series propagation aggregation on the time series of the body composition time series association implicit feature vectors to obtain a body composition time series propagation aggregation representation vector as the body composition time series association aggregation feature; a fat reduction training program semantic encoding unit 833, which is used to perform global semantic encoding on the fat reduction training program to obtain a fat reduction training program semantic encoding feature vector as the fat reduction training program semantic encoding feature.

[0059] Specifically, in the feature mining process of the time series of the body composition data and the fat loss training program, first of all, considering that the body composition data contains a variety of physiological indicators, each indicator reflects different aspects of the human body's physical state, and there is a certain correlation between different body composition parameters. Therefore, in order to fully understand the body composition status of the monitored object at each time point, the present application uses a body composition embedding matrix to embed and encode each body composition data in the time series of the body composition data, map the body composition data at each time point into a high-dimensional feature space, reveal the potential correlation between different body composition parameters, and more comprehensively understand the physical condition of the monitored object, so as to generate a time series of body composition fully connected embedded coding vectors.

[0060] Next, in order to capture the dynamic trend of body composition data changing over time, the present application introduces a body composition time series association encoder based on the Bi-LSTM model to perform time series association analysis on the time series of the body composition fully connected embedded coding vector, so as to utilize the bidirectional information transmission characteristics of the Bi-LSTM model to capture the forward and backward dependencies of the body composition data in time, accurately reveal the inherent laws and trends of changes in the human body state, and use the outputs of each hidden layer in the Bi-LSTM model as the time series of the body composition time series association implicit feature vector, so as to provide strong data support for the subsequent adjustment of the fat reduction training program.

[0061] Correspondingly, the body component data time series association analysis unit 831 includes: an embedding coding subunit, which uses a body component embedding matrix to perform embedding coding on each body component data in the time series of the body component data to obtain a time series of body component fully connected embedded coding vectors; and a time series association coding subunit, which performs time series association coding on the time series of the body component fully connected embedded coding vectors to obtain a time series of the body component time series association implicit feature vectors.

[0062] Among them, the temporal association encoding subunit is used to: input the time series of the body component fully connected embedded coding vector into the body component temporal association encoder based on the Bi-LSTM model to obtain the time series of the body component temporal association implicit feature vector.

[0063] Furthermore, in order to integrate the body composition information of the monitored object in the global time domain and obtain the global change characteristics of its body state in the time dimension, the present application further introduces a feature forward propagation network based on the significant time series decay of node energy to aggregate the time series of the implicit feature vector associated with the body composition time series. Specifically, the feature forward propagation network based on the significant time series decay of node energy first calculates its energy significant descriptor according to the mean and variance of each body composition time series associated implicit feature vector to quantify its feature importance. Subsequently, the time information is assigned to the implicit feature vector associated with the body composition time series of each time node, and the time series decay mechanism is used to generate the corresponding energy time decay factor based on the time span between the implicit feature vector associated with the body composition time series of each historical time node and the current (i.e., the end of the time series) body composition time series associated implicit feature vector, so that when the weighted feature is aggregated, the features can be aggregated based on the feature significance of each time node and the time series decay characteristics of the information to generate a body composition time series propagation aggregation representation vector. In this way, not only can comprehensive information on changes in body composition of the monitored subjects during the fat loss process be unearthed, but the importance of recent changes is also highlighted through the time-series decay mechanism, thereby enhancing the timeliness and accuracy of fat loss training management.

[0064] At the same time, in order to understand the deep meaning of the fat-reducing training program set by the user, the fat-reducing training program is further semantically encoded, and the pre-trained natural language processing model is used to deeply analyze the various exercise types, intensities, frequencies, durations and other information in the fat-reducing training program, and extract the contextual semantic feature representation of the fat-reducing training program to obtain the semantic encoding feature vector of the fat-reducing training program, which is used for the subsequent correlation analysis between the training program and the changes in body composition. In an embodiment of the present application, a semantic encoder based on a Transformer structure can be used to implement this semantic encoding process.

[0065] Correspondingly, the body component feature time series propagation aggregation unit 832 is used to: input the time series of the body component time series associated implicit feature vector into the feature forward propagation network based on the significant time series attenuation of node energy to obtain the body component time series propagation aggregation representation vector.

[0066] Specifically, the body component feature time series propagation aggregation unit 832 includes: an energy significant descriptor calculation subunit, which is used to calculate the energy significant descriptors of each body component time series associated implicit feature vector based on the mean and variance of each body component time series associated implicit feature vector in the time series of the body component time series associated implicit feature vector to obtain a time series of energy significant descriptors; a timestamp marking subunit, which is used to extract the timestamps of each body component time series associated implicit feature vector in the time series of the body component time series associated implicit feature vector to obtain a time series of timestamps; a historical node feature division subunit, which is used to use the body component time series associated implicit feature vector corresponding to the current time point in the time series of the body component time series associated implicit feature vector as the current body component time series associated implicit feature vector, and use the body component time series associated implicit feature vectors corresponding to other time points as the historical body component time series associated implicit feature vectors to obtain the current body component time series associated implicit feature vector. A time series of time-series-associated implicit feature vectors and historical body component time-series-associated implicit feature vectors; a decay factor calculation subunit, used to calculate the energy time decay factor of each historical body component time-series-associated implicit feature vector in the time series of the historical body component time-series-associated implicit feature vectors relative to the current body component time-series-associated implicit feature vector to obtain a time series of energy time decay factors; a historical node propagation aggregation subunit, used to perform time propagation aggregation on the time series of the historical body component time-series-associated implicit feature vectors using the time series of the energy-significant descriptors as a positive adjustment factor and the time series of the energy time decay factors as a negative adjustment factor to obtain a historical node body component time-series propagation aggregation representation feature vector; a global time-series aggregation subunit, used to fuse the historical node body component time-series propagation aggregation representation feature vector and the current body component time-series-associated implicit feature vector to obtain the body component time-series propagation aggregation representation vector.

[0067] Among them, the attenuation factor calculation subunit is used to: calculate the timestamp difference between the historical body composition time series associated implicit feature vector and the current body composition time series associated implicit feature vector; round down the timestamp difference and divide it by the preset time attenuation period and then square it, and multiply the square result by the preset attenuation rate to obtain the initial energy attenuation coefficient; calculate the exponential function value with the natural constant as the base and the initial energy attenuation coefficient as the exponent to obtain the energy time attenuation factor.

[0068] In a specific example, the body component feature time series propagation aggregation unit 832 is used to process the time series of the body component time series associated implicit feature vector using the following time series propagation fusion formula to obtain the body component time series propagation aggregation representation vector, wherein the time series propagation fusion formula is:

[0069] X={x1,x2,...x k-1 ,x k}

[0070]

[0071] Wherein, X represents the time series of the implicit feature vector associated with the time series of the body component, the value of k is the number of feature vectors in the time series of the implicit feature vector associated with the time series of the body component, and x1, x2, x i 、x k-1 and x k respectively represent the first, second, ith, k-1th and current body component temporal association implicit feature vectors in the time series of the body component temporal association implicit feature vectors, represents the jth eigenvalue of the temporal association implicit feature vector of the i-th body component, the value of L is the length of the temporal association implicit feature vector of the i-th body component, μ i is the characteristic mean of the temporal association implicit characteristic vector of the i-th body component, σ 2 i is the characteristic variance of the implicit characteristic vector associated with the i-th body component time series, represents the fourth-order central moment of the i-th body component time series associated implicit feature vector, that is, the expected value of the fourth power of the difference between each eigenvalue in the i-th body component time series associated implicit feature vector and its mean, is the energy significant descriptor of the temporal association implicit feature vector of the i-th body component, is the energy significant descriptor of the implicit feature vector associated with the current body component time series, t k The timestamp representing the temporal association implicit feature vector of the current body composition, t i represents the timestamp of the temporal association implicit feature vector of the i-th body component, represents rounding down, β represents the preset decay rate, L represents the preset time decay period, exp(·) represents the exponential function operation, α is the weight hyperparameter, x k+1 A representation vector representing the temporal propagation aggregation of the body components.

[0072] Furthermore, by calculating the semantic offset difference representation vector between the semantic encoding feature vector of the fat loss training program and the body composition temporal propagation aggregation representation vector, the semantic deviation between the fat loss training program and the body composition changes of the monitored object can be quantified, thereby revealing whether the execution effect of the training program is consistent with the physical change trend of the monitored object, and using this as a key basis for evaluating whether the training program needs to be adjusted.

[0073] Then, the semantic shift differential representation vector is input into the classifier-based training management result generator to obtain the training management result. In the technical solution of the present application, the classifier-based training management result generator adopts a fully connected neural network structure to classify and predict the adaptability of the fat reduction training program according to the characteristic distribution of the semantic shift differential representation vector to determine whether the current fat reduction training program needs to be adjusted. In this way, the fat reduction training program can be dynamically evaluated and optimized to ensure that it always maintains a high degree of fit with the physical condition of the monitored subject, thereby improving the scientificity and efficiency of the fat reduction process.

[0074] Correspondingly, the training management result generation module 840 includes: a position difference unit, used to calculate the position difference between the semantic encoding feature vector of the fat loss training program and the body composition temporal propagation aggregation representation vector to obtain a semantic offset difference representation vector; a training management result generation unit, used to input the semantic offset difference representation vector into a classifier-based training management result generator to obtain the training management result.

[0075] It should be understood that the role of the classifier is to use the given categories and known training data to learn classification rules and classifiers, and then classify (or predict) unknown data. Logistic regression and SVM are often used to solve binary classification problems. For multi-class classification problems, logistic regression or SVM can also be used, but multiple binary classifications are required to form a multi-classification. However, this is prone to errors and is not efficient. Commonly used multi-classification methods include the Softmax classification function.

[0076] In a preferred example, considering that the semantic encoding feature vector of the fat loss training program and the body composition temporal propagation aggregate representation vector respectively represent the textual semantic features of the fat loss training program and the body composition temporal associated implicit aggregate propagation features, after calculating the semantic shift differential representation vector between the semantic encoding feature vector of the fat loss training program and the body composition temporal propagation aggregate representation vector, the obtained semantic shift differential representation vector will also cause decoding semantic regression offset due to the feature distribution mode and timing differences between the semantic encoding feature vector of the fat loss training program and the body composition temporal propagation aggregate representation vector, thereby causing outlier class regression inference mapping deviation, and further affecting the accuracy of the training management result obtained by inputting the semantic shift differential representation vector into the classifier-based training management result generator.

[0077] Based on this, when the semantic shift differential representation vector is input into the training management result generator based on the classifier to obtain the training management result, the semantic shift differential representation vector is optimized. Accordingly, the training management result generating unit includes: an optimization subunit, which is used to optimize the semantic shift differential representation vector to obtain an optimized semantic shift differential representation vector; and a classification subunit, which is used to input the optimized semantic shift differential representation vector into the training management result generator based on the classifier to obtain the training management result.

[0078] Wherein, the optimization subunit is used to: calculate the feature mean of the semantic shift differential representation vector, and divide the feature mean by the difference between the maximum eigenvalue and the minimum eigenvalue of the semantic shift differential representation vector to obtain a distribution representation value of the semantic shift differential representation vector; subtract the distribution representation value of the semantic shift differential representation vector and divide it by the distribution representation value of the semantic shift differential representation vector to obtain a distribution modulation value of the semantic shift differential representation vector; activate the semantic shift differential representation vector through a probabilistic function to obtain a probabilistic semantic shift differential representation vector; perform point subtraction between the probabilistic semantic shift differential representation vector and the distribution modulation value of the semantic shift differential representation vector, take the absolute value and calculate The negative of the logarithmic value with base 2 is used to obtain a probabilistic semantic shift differential representation vector distribution modulation information vector; after dividing the semantic shift differential representation vector distribution representation value by one minus the difference of each eigenvalue of the probabilistic semantic shift differential representation vector, all eigenvalues ​​of the probabilistic semantic shift differential representation vector are summed and divided by the length of the semantic shift differential representation vector to obtain a probabilistic semantic shift differential representation vector distribution modulation bias value; and the product of the probabilistic semantic shift differential representation vector distribution modulation information vector and the probabilistic semantic shift differential representation vector distribution modulation bias value and the weight as a hyperparameter is dotted to obtain an optimized semantic shift differential representation vector.

[0079] In a specific example, the optimization subunit is used to optimize the semantic shift differential representation vector using the following optimization formula to obtain the optimized semantic shift differential representation vector; wherein the optimization formula is:

[0080]

[0081] And among them:

[0082]

[0083] in, represents the feature mean of the semantic shift differential representation vector, v max and v mindenote the maximum eigenvalue and the minimum eigenvalue in the semantic shift differential representation vector, respectively; p denotes the distribution representation value of the semantic shift differential representation vector; V denotes the probabilistic semantic shift differential representation vector obtained after the semantic shift differential representation vector is activated by a probabilistic function; and v i represents the i-th eigenvalue of the probabilistic semantic shift differential representation vector, log represents the logarithmic function value with base 2, ε is the weight as a hyperparameter, the value of L is the length of the probabilistic semantic shift differential representation vector, and V' represents the optimized semantic shift differential representation vector.

[0084] That is, in the above preferred example, the eigenvalue-based probability information distribution planning of the semantic shift differential representation vector is performed by using the Bernoulli probability modulation distribution of the semantic shift differential representation vector relative to the eigenvalue distribution, and the probability reverse mapping of the probability features of the semantic shift differential representation vector as a whole is used as an extended coverage of the set mapping space of the semantic shift differential representation vector to independently understand the interaction path between the intuitive probability information distribution and the abstract probability space mapping of the semantic shift differential representation vector, so as to improve the accuracy of the training management results obtained by inputting the optimized semantic shift differential representation vector into the classifier-based training management result generator by avoiding the counterfactual reasoning mapping of the outlier feature distribution of the semantic shift differential representation vector to the class regression probability.

[0085] Accordingly, the present application also provides an electronic device, comprising: a memory for storing instructions; a processor coupled to the memory, the processor being configured to execute the fat loss training management device based on big data as described in any of the preceding items based on the instructions stored in the memory.

[0086] Based on the above embodiments, see Figure 3 As shown in FIG. 1 , it is a flow chart of a fat loss training management method based on big data in an embodiment of the present application. Figure 3 As shown, according to the fat loss training management method based on big data according to the embodiment of the present application, the steps include: S510, obtaining the time series of body composition data of the monitored object, wherein the body composition data includes weight, body fat percentage, muscle mass, bone mass, water content, basal metabolic rate, visceral fat level, body age, protein content, body mass index and lean body weight; S520, receiving a fat loss training plan input by a user; S530, feature encoding the time series of the body composition data and the fat loss training plan to obtain body composition time series associated aggregation features and fat loss training plan semantic coding features; S540, determining the training management result based on the body composition time series associated aggregation features and the fat loss training plan semantic coding features, and the training management result is used to indicate whether the fat loss training plan needs to be adjusted.

[0087] Here, those skilled in the art can understand that the specific operations of each step in the above-mentioned fat loss training management method based on big data have been referred to above. Figure 1 to Figure 2 It has been introduced in detail in the description of the big data-based fat loss training management device 800, and therefore, its repeated description will be omitted.

[0088] Figure 4 FIG. 1 is an application scenario diagram of a fat loss training management device based on big data according to an embodiment of the present application.
