## Abstract

Radial neural network is based in the world with the characteristics of active adaptation, active learning, active recognition, low error rate, and thought mapping and plays an important role in personalized regulation. However, in practical applications, due to the existence of pattern recognition, motion control, and a large amount of combined knowledge, the traditional methods are difficult to solve, even powerless, and cannot be effectively solved. Although the traditional BP network is more widely used, the BP neural network is easy to enter the regional minimum value during the training process, which leads to a lower training learning speed and low efficiency. The RBF network (radial neural network) is in a certain sense, and it can detect both known intrusions and unpredictable intrusions. At the same time, it is superior to BP neural network in data collection, pattern recognition, and personality customization. Through detection and comparison, it is found that the radial network has improved the analysis speed by about 20%, and the degree of privacy protection of athletes is as high as 99%, which is close to the full value, and the accuracy of the psychological control scheme is also improved by about 15% on the basis of the classic network. Athletes can be adjusted as soon as possible to achieve the best state; so, it will be an ideal choice to use a radial neural network for the psychological adjustment detection system.

## 1. Introduction

Neural network processing is a new type of psychological regulation detection mode in recent years. A variety of modes can be flexibly configured to meet the individual needs of athletes. As we all know, neural network is an important means in data classification. It can classify and predict data; so, it has great development prospects in information processing, pattern recognition, and other fields. In recent years, neural network-based algorithms and neural network-based learning have attracted widespread interest in industry and academia, and well-trained neural networks are gradually being valued by many companies. When using neural networks to conduct psychological tests, the data is usually stored in a special organization; so, how to protect the personal information of athletes has become a very critical issue. Compared with athletes, privacy protection is very passive. Although the security technology of neural networks is constantly developing, it is more based on strategic-level access control. When the defense system is destroyed, the user’s data will be directly exposed. The characteristics of the state password are exactly in line with the confidentiality and operational needs of data. In addition, the current BP neural network algorithm is widely used, but in the case of a large amount of calculation, it cannot work well in a limited computing resource environment, because it can get the information it needs without exposing its own information. And even the data obtained by an attacker breaking through a defense is useless. The RBF network (radial neural network) was introduced, a service that provides an efficient classification and processing method for complex neural network operations but at the same time brings the danger of privacy leakage.In view of the above problems, on the original basis, the neural network is improved by applying homomorphic cryptography technology, and its detection process is improved to ensure the privacy of data. Compared with traditional privacy-based neural networks, this method is more suitable for complex neural networks and has higher security. There are two reasons for the processing of private data. First, you can get the information you need without revealing your own information to others. Second, the information and data obtained by attackers breaking through defenses are useless. To put it simply, when obtaining personal information, it will protect its own information well. If it does not disclose it, no one or anything will know it. In addition, even if the system is attacked and information is leaked, the self-protection mode will be turned on, and only the data of no use value is leaked out.


## 2. Related Work

He et al. discussed the robust estimation of a class of uncertain neural networks with time delay. On this basis, the uncertainty of the parameters is assumed to be norm-bounded. Based on a new bounding technique, a sufficient condition to guarantee the existence of a desired state estimator for uncertain delay neural networks is proposed including data calculation, time length, and program applicability. This measurement is based on the magnitude of the time change delay and the magnitude of the time lag. It is shown that the design of a statistical solid state for such neural networks can be accomplished by selecting linear matrix inequalities (LMIs), which can be easily achieved using certain standard arithmetic factors [1]. Alanis explained the results of using a common grid training algorithm based on the Kalman enhanced filter and its application in electricity cost forecasting. In addition, it includes stability elements using the well-known Lyapunov method for training artificial intelligence networks using algorithms based on the Kalman enhanced filter. Finally, the usefulness of the proposed forecasting idea is demonstrated by step-by-step and step-by-step forecasting using data from the European electricity system [2]. A class of multiobjective nonlinear systems with time-delay characteristics is studied, and a state-delay-based coordinated control method is proposed. Most of the previous works only focus on linear systems with input time-delay. Chen et al. proposed an intelligent and active adaptive neural network consensus control method. Proximity properties of radial base radiation networks (RBFNN) are used to neutralize nonconventional forces on agents. The Lyapunov-Krasovskii project, derived from the derivative of the Lyapunov project, was used to compensate for the uncertainty of the unknown delay [3]. Jiang et al. studied the challenging problem of classifying videos based on high-level semantics, such as the presence of specific human actions or complex events, and extensive efforts have been made in recent years, but most existing works combine multiple video features, while ignoring the exploitation of interclass semantic relations. Specifically, estimating and exploiting these two types of relations by imposing regularization during the learning process of deep neural networks (DNNs) showed that rDNNs yield better performance than several state-of-the-art methods [4]. Efficient neural network system emotion regulation is critical to mental health and well-being, providing insights into the underlying mechanisms that promote this critical skill. Nook et al. combined principles from cognitive linguistics and basic emotion science to test whether changes in a person’s language components could promote effective emotion regulation. In particular, the bidirectional relationship between language features of emotion regulation and psychological distancing was explored [5]. Ray-Yol and Altan-Atalay stated that people often use their interactions with others to control their emotions, known as the emotional process. Limited studies have investigated the relationship between IER and stress, and no one has addressed the role of mediators in this relationship. Current research is aimed at exploring the role of the prospective cognitive test, which is defined as an individual’s confidence in the effectiveness of his or her cognitive skills when combined with difficult emotions [6]. Stress is one of the psychological reactions that accompany users. Stress levels can affect a user’s mental health. Gunawan and Bintari have found through the previous research that there is a relationship between neural network emotion regulation and stress and mental health, in which high levels of stress will reduce mental health; that is, due to various objective factors or environmental influences, the psychological pressure is unbearable and unbearable, and the psychology must be unhealthy. Conversely, low stress can even heal itself, while individualized regulation can reduce stress and maintain individual mental health. Expression inhibition and cognitive reappraisal emotion regulation strategies are defined as the ways in which individuals affect, feel, and express emotions [7]. Shouket’s study investigated the basic psychological changes, basic psychological needs (autonomy, ability, and relevance), and cognitive emotion regulation strategies of residents in a certain place, and the analysis showed the relationship between the research variables: life satisfaction, psychological needs, and cognitive emotion adjustment strategy. Relevance satisfaction and autonomy satisfaction positively predict life satisfaction. However, with unmet associative needs and catastrophically negative predictions of life satisfaction, findings can vary widely [8].


## 3. Superiority of Radial Neural Networks in the Field of Psychological Regulation

### 3.1. Working Principle and Value of Radial Neural Network Regulation and Prediction

Different from the traditional theoretical derivation methods in the past, the traditional method basically runs without loops, information, can only flow forward, and cannot process the data well; so, there are great limitations. The RBF neural network collects a large amount of existing data, analyzes different individuals, and finally obtains the best fitting result, which truly reflects the characteristics of individualization [9]. The principle is to first analyze and compare a large amount of existing basic data in the early stage through the input layer. Of course, these data are also collected by the early stage system, then use the hidden layer to train the data, and finally, output the predicted result. If the discrepancy is large, it is calculated again, and the weights are redistributed to obtain the best fit of the athletes. In addition, the subjective emotions and subjective emotions of the players also need to be collected. The RBF neural network has become a bridge between influencing factors and subjective feelings, so that the results meet the needs of psychological regulation detection [10].In competition, athletes, especially elite athletes, are often affected by psychological factors. Secondly, whether they are indoors or outdoors, their playing field is very different from the normal training time. For example, sudden noise, harsh environment, and large competition pressure will greatly affect the performance and performance of a good athlete [11]. In addition, in the years of research, although there have been some studies on the psychological adjustment methods of athletes of various special events, so far, there is no accurate model that can predict the psychological adjustment of athletes on the field [12]. That is to say, the current research is still in the stage of “medicating the head with a headache and treating the foot with a sore foot.” It is very difficult to formulate tactics and psychological adjustment strategies according to individual conditions before the competition. The improvement in performance is very limited [13]. Therefore, in the game, the radial neural network can be used to make various predictions and prescribe the right medicine, and through training, the athletes can gradually adapt to the game or make psychological adjustments in emergencies, to achieve the best competitive state. To achieve the desired effect, it is of great significance to formulate targeted tactics and achieve the best results [14].


### 3.2. Difference between Radial Neural Network (RBF) and Classical BP Neural Network

Neural network is a hot topic in the field of artificial intelligence at present. It is an abstract brain neural network. By mapping the input and output data linearly or nonlinearly, the trained neural network can effectively classify and identify data. Therefore, the corresponding regulation detection can be carried out accurately [10]. Generally, a neural networks can be divided into a single hidden layer forward network (radial neural network) and classical multilayer neural networks (BP network). The radial neural network is divided into the following: input layer, hidden layer, and output layer. All information starts from the input layer, goes through the hidden layer, and then passes through the input layer to the output layer, so that the feedforward system does not have periodic or infinite loops [15].The traditional neural network mainly includes BP neural network, SOFM neural network, and Boltzmann machine. These networks have leaked amid a massive increase in the number of users which made athletes, even ordinary users, particularly worried about their privacy leakage. At the same time, in practice, the individualized requirements of a large amount of data and the individualized combination problems such as pattern recognition cannot be solved by classical networks [16]. In terms of individualized adjustment, radial neural network technology can summarize the “relationship” between subjects and influencing factors from a large number of existing evaluation data, to predict unknown results [17]. In sports psychology, through the prediction of the sound scene of the game, the mental state of the athletes can be adjusted, which provides a new research method for the preparation of athletes in the future. The homomorphic encryption algorithm is added to the design, which solves the problem of privacy leakage. Not only can it obtain the detection results it wants without exposing its own information but even if it is attacked by the enemy, the other party will only get some meaningless ciphertext [18]. It is shown in Table 1.Table 1

### 3.3. Psychological Regulation Detection and Neural Network Are Inseparable

Radial neural network (RBF) is a three-stage forward neural network design, and its composition is shown in Figure1. The input layer starts from the case where the training sample size is equal to the sample size, and the transfer function is linear. The Gaussian function is a nonnegative nonlinear function whose center decays radially symmetrically [19]. Therefore, near the central area of the basis function, the radial basis node output of the network has a large value, which makes the network have a strong local approximation, the so-called local approximation means that the approximation of the objective function is only based on the data near the query point, which means that the network needs to modify the ownership values, and only a small part of the weights needs to be modified locally. And therefore, the learning efficiency of the model is high. The transfer function of the output layer is the output of a linear radial basis neuron. Since the RBF network (radial neural network) can approximate any nonlinear function, it can solve its inherent unsolvable laws, it has good classification performance, and the learning convergence speed is fast; so, the RBF network has been widely used [20]. At the same time, it is also because of the diversification of individual needs that the traditional BP network is difficult to solve or even unable to handle, which leads to further research on the basis of the traditional BP network to improve the training speed and efficiency, as well as the ability to identify and distinguish. The radial neural network researched from this can solve the above problems very well. On the other hand, whether ordinary users or athletes want to conduct personalized psychological regulation testing, they must not want to reveal personal privacy in this era of big data. RBF network maintains the computability of data while ensuring data privacy [21].Figure 1
Neural network structure diagram.


### 3.4. Psychological Regulation of Athletes before the Competition

In different sports, athletes’ resistance to pressure, tactics, and physical fitness will change as the game progresses. And as the athlete’s fighting ability is getting stronger and stronger, the mentality is a great influence. A person’s emotional fluctuations are likely to cause huge fluctuations in people’s mentality, thus affecting the final outcome. The real ability cannot be brought into full play. Therefore, excellent sports teams at home and abroad attach great importance to psychological counseling before the game and regard it as an important means to improve the athletes’ competitive state. At present, the three major types of mental states are overexcited, too indifferent, and too blindly confident; although, the reasons for these states may include many aspects. The athlete’s prematch psychological regulation program includes many aspects, mainly including the athlete’s psychological changes, the athlete’s on-the-spot pressure, and self-psychological adjustment. Using these relationships, radial neural networks are used to predict unknown outcomes. At the same time, from the aspects of improving self-confidence without overconfidence, setting reasonable goals for the best matching degree, predicting the competition in advance, simulating relatively consistent training before the competition, and accumulating psychological potential, the unhealthy state of athletes can be effectively controlled. It allows athletes to focus on getting ready for the competition. The flow chart of psychological regulation is shown in Figure2.Figure 2
Flow chart of psychological regulation.


### 3.5. Privacy-Preserving Homomorphic Encryption Functions in Neural Networks

The homomorphic encryption algorithm is an additive homomorphic, finite-time multiplication homomorphic symmetric encryption algorithm, and its homomorphic characteristic is that it performs certain operations on the ciphertext and corresponds to the operation result of the plaintext.The analysis process of this algorithm is as follows:Denote this square as KG:(1)p,q,s⟵KGλKG is a big prime number withSK=s,q,p>q, the extent of q is λ, and s is a stochastic digit in Zp∗.Cryptographic algorithm is as follows:LetM denote a cryptographic operation:
(2)MFE,m,d=sdr.q+nmodp.M is a cipher key with plaintext N and d as the password. For n∈F_q, the cipher algorithm will obtain a ciphertext C.The probability algorithm formula of FE is as follows:(3)MFE,n,d=r.q+nmdp⟵MFE,n,d.d is an alternative decimal, d is called an encrypted text level, c is a level d term, and r is a good ID number. Let r be the extent of r, and q and p be the extent of q and p. These must meet r+q<PP. Apparently, in encrypted text c, r is a random attribute used to encrypt the word n.Sometimes, because there is no incentive function, it is impossible to accurately express different user data and category identification. Therefore, the homomorphic encryption technology is used to identify and classify different state data. At the same time, considering the influence of excitation, the excitation function of the segmented structure is adopted, so that each segmental function has a linear characteristic.(4)k1×x+b1,x⩽n1,k2×x+b2,n1>x⩾n2,k3×x+b3,n2>x⩾n3,⋯ki×x+bi,ni>x⩾ni+1.On this basis, this paper designed a privacy-based security architecture in a specific application environment. Data owners are reluctant to leak their data to algorithm owners and cloud users nor to leak their neural networks to users. Still, the desired result can be detected. Figure3 shows the privacy protection structure diagram.Figure 3
Neural network structure diagram for privacy protection.The first step is that in the above excitation function, because the input algorithm is encrypted, it cannot be directly added to b. Therefore, to facilitate the calculation, the algorithm holder will send the incentive function parameterb to the data holder and generate a key:
(5)SKs,q,p=KeyGenλ.Generate a random numberri, encrypt the parameter b, and return it to the algorithm holder:
(6)cbi=ESK,bi,d=sdr1q+bimodp.The person who has the data that locally encrypts the data matrix [m1,m2,···,mi] encrypts this data matrix locally. Using the selected random number and the first generated key SK, the randomly selected Count ri to get the ciphertext ci,
(7)ci=ESK,mi,d=sdriq+mimodp.Homomorphic cryptography is widely used in secure multiparty computing technology. It can effectively reduce the use of user data in the network, and personal privacy data has been protected by the naked eye.

## 4. Data of Classical Neural Networks and Radial Neural Networks in the Field of Psychological Regulation

Through data comparison, it is found that the use of a radial networks for personalized psychological adjustment allows athletes to adjust to the best preparation state at the fastest speed and concentrate on preparing for the competition. At the same time, formulate appropriate game goals and prematch preparations, that is, to give the athlete confidence but not overconfidence as well as formulating appropriate game goals, predicting in advance, and accumulating psychological potential and explosive power relative to simulation training. Including in real life, there is a lot of pattern recognition, motor control, and a lot of combined knowledge processing that will help athletes adjust before the game. However, traditional network methods are difficult to deal with or even powerless, and the capabilities in various aspects are relatively weak, such as pattern recognition, classification, and personalization capabilities.Among them, the typical states are divided as follows: (1) the research results show that 18% of the players have excessive emotional fluctuations, frequent movements, and improper distribution of power. According to statistics, the excitement rate before the game is 78%. Therefore, adjusting the athletes’ emotions is an important measure to get the best results in the game. (2) The results show that 13% of the athletes are in a passive state in the game. During the game, their physical strength will drop significantly, there will be obvious mistakes, and they may even abstain directly, but some players said after the game that their performance was not ideal. (3) In this study, 16% of the people are blindly confident that they are usually very competitive in a game, and they want to eat a fat man in one bite. However, once something goes wrong, his mental state will plummet, and he will be slow, bewildered, and restless, eventually leading to one defeat after another. Finally, he no longer had the strength to confront his opponent head-on. The above three kinds of bad mentality have a negative impact on the overall quality of the athletes and have a profound impact on the success or failure of the competition, which can better reflect the importance of neural networks to the psychological regulation of athletes. It is shown in Table2.Table 2
Control analysis data ratio in different states.

Specifically, it can be reflected in the speed of data identification and analysis, the output accuracy of the personalized regulation scheme, the speed of entering the best state after regulation, the degree of personal privacy protection, and the ability to detect known intrusions and unpredictable intrusions. As is shown in Figure4, the two kinds of neural network analysis speed are compared.Figure 4
Comparison of two kinds of neural network analysis speed.From the graph data, it can be found that the speed of classic BP network analysis data is generally only about 83%. This experiment only extracts a part of the target for detection. It is conceivable that large-scale data combinations and other large-scale data may cause system paralysis at the same time. The radial neural network data analysis speed is basically full. Even if a large amount of data is identified and analyzed at the same time, the speed will be more than 90%. For an athlete, saving time is also getting yourself into the best shape at the fastest speed. The maximum efficiency is to regulate the athletes’ psychology. Through training, the athletes can gradually form a psychological adaptation to the game or adjust their mentality in time during the game, to achieve the best competitive state and achieve the expected effect. As is shown in Figure5, the personalized scheme outputs the accuracy.Figure 5
The output accuracy of the personalized scheme.Judging from the accuracy of targeted and personalized psychological regulation detection, the classical neural network follows the traditional theoretical derivation method step by step and gradually obtains big data to customize the corresponding plan. However, the probability of large discrepancies in the forecast results is relatively high, which requires continuous recalculation, redistribution, reidentification, statistical analysis, and so on. Excessive consumption of time may lead to an athlete’s psychological incompatibility with the original basis. Radial neural network is different from the traditional theoretical derivation method in the past. The RBF neural network collects a large amount of existing data and analyzes different individuals differently and obtains the best fitting result at the widest speed. The accuracy rate is as high as 98%, and the error rate is extremely low. It truly reflects the characteristics of individualization. On another level, it will not increase the psychological pressure of athletes and even has a certain soothing effect. Figure6 shows the module flow of the personalized regulation system.Figure 6
Module flow of the personalized regulation system.Figure7 shows the degree of personal privacy protection.Figure 7
Degree of personal privacy protection.Through surveys of sports teams in different countries, it is found that when athletes use neural networks for psychological testing, they usually need to provide data to specialized organizations. For athletes, privacy protection is very passive. Although both types of networks have good security guarantees, in traditional networks, access control is generally based on policy level. Once the defense is broken, it is exposed to the attack side, and the security cannot be guaranteed. Therefore, there is a big limitation. However, the RBF Network (radial neural network) service provides a solution, on which the radial neural network is based. This paper introduces a neural network implemented using homomorphic encryption technology, which not only ensures the privacy of data but also ensures its computability. The advantage is that you can get the information you need without revealing your information to the enemy. The second is that the attacker breaks the defense, and the information obtained is just a bunch of meaningless data. As is shown in Figure8, the time comparison of entering the best state after regulation is shown.Figure 8
Comparison of the time to enter the best state regulation.Through the sampling experiment of three different samples with two kinds of neural networks, it can be seen that after a series of analysis and comparison of the classical network to give a plan, most athletes need about fifteen minutes to adjust to a relatively optimal state. For the psychologically tense situation before the game, the time-consuming is still relatively long, the radial neural network basically takes less than ten minutes or even less, and the development prospect is excellent. For the originally tense psychological state, there is auxiliary relief before the implementation of the program regulation. To a certain extent, it has also reduced some of the three common phenomena of excessive excitement, indifference before the game, and blind confidence.


## 5. Conclusion

This paper starts from reality, and after a lot of investigations, it is found that the classical neural network has a slow speed and low efficiency and cannot meet individual needs, let alone formulate a personalized regulation scheme. At the same time, when attacked, it cannot be processed quickly or may even be directly helpless, while radial neural network processing gradually replaces the classical network with the advantages of self-adaptation, self-learning, self-organization, associative memory, and associative mapping. Radial neural network detection has the following characteristics: collect a large amount of data using scientific methods and identify and analyze customized personalized methods and scientific model building. To ensure the accuracy of the model, it can clearly reflect the athlete’s feeling in a specific space environment, so that one-to-one formulating plans can be adjusted in the shortest time to achieve the best state. It is also available to professionals of all kinds. Just by entering the factors that people are interested in, it can automatically make predictions and adjust them to make the most of the situation. It also protects privacy, can quickly resolve known intrusions, and can detect unpredictable intrusions and kill them in the cradle. According to the abovementioned characteristics, it will provide new ideas for the precompetition psychological adjustment and precompetition individualized strategy formulation of Chinese elite athletes and has a very broad development prospect.
