## Abstract

Aesthetic education is an important part of education. However, sports action teaching and aesthetic education are closely combined. This paper discusses the important role of aesthetic education in action teaching through the relationship between action education and aesthetic education. And put forward how to cultivate students’ ability of feeling beauty, understanding beauty, and expressing beauty through various aesthetic education means such as teachers’ aesthetic education ability, optimizing teaching process and beautifying teaching environment. Based on the research of aesthetic education and action education, this paper mainly uses data mining methods, such as statistical analysis and clustering, to further mine the patterns and events obtained before, so as to form a higher level of semantics. From the two directions of motion recognition algorithm and continuous motion segmentation, the feature classification method based on depth and joint data and the segmentation algorithm based on sliding window are studied to achieve the research purpose. In the experimental part, the algorithm is tested and analyzed based on the action data set, and the correctness and effectiveness of the algorithm are verified.

## 1. Introduction

The frequency, time, and intensity of contemporary college students’ physical exercise behavior in sports are decreasing year by year, and the problems of low awareness and aesthetic level of physical exercise are becoming increasingly prominent [1]. Sports culture is a kind of “game” to enjoy spiritual freedom in the form of limbs, which advocates the “transcendence” of limited life to infinite spirit [2]. However, in reality, due to the influence of instrumental rationality for a long time, sports culture only pays attention to extracting the external “form” of sports culture after curriculum but ignores its internal “meaning.” Using epistemological framework to standardize physical education curriculum, in order to obtain the effect of skill education and body development, deviates from the understanding that sports is beyond natural life to some extent [3]. In order to bring up a young generation with all-round development, it is necessary to carry out aesthetic education in the process of sports teaching for students, apply aesthetic principles, implement aesthetic education, organically combine sports and aesthetic education in teaching practice, and cultivate students’ ability to appreciate, create, and express beauty in sports activities [4]. Through physical education, students’ body and posture become more perfect, so that aesthetic education can play a promoting role in the process of physical education and better serve the construction of spiritual civilization [5]. Cultivate students into a new generation with all-round and full development in morality, intelligence, physique, and beauty. Therefore, how to integrate aesthetic education into sports action education, so as to effectively cultivate students’ aesthetic ability, is a topic worthy of study [6, 7].With the continuous advancement and deepening of educational informatization, while improving the teaching and management efficiency of schools at all levels, a large number of educational data resources, namely, educational big data [8], have also been produced. Education data covers a wide range, including the whole education chain of students from enrollment to graduation, such as basic information of students, information of students’ achievements, and information of students’ evaluation of teaching. Using data mining technology [9] to support school teaching management and decision-making is a critical foundation for today’s teaching management reform in colleges and universities. It is an important part of aesthetic education, and it teaches the younger generation how to properly feel, appreciate, and create beauty. It is necessary to carry out aesthetic education in the process of physical education for students, apply aesthetic principles, implement aesthetic education, organically combine physical education with aesthetic education in teaching practice, and cultivate students’ ability to appreciate, create, and express beauty in sports activities in order to bring up a young generation with all-round development [10]. As a result, aesthetic education in physical education serves as both a means of cultivating and shaping all-round development talents. In sports teaching, there are many factors of aesthetic education, and making full use of these factors can help a lot [11]. This paper makes a relatively in-depth study of aesthetic education and action education, and based on modern technology, it puts forward a teaching method combining aesthetic education and action education based on data mining.The increasing proliferation of multimedia data has brought greater difficulties to the rapid retrieval and query of data [12]. However, the majority of users hope to quickly extract interesting content and implicit knowledge from multimedia data, so that they can be used to quickly search and query and at the same time provide decision support for problem solving. With the rapid development of cloud computing and artificial intelligence technology [13], more and more scholars and researchers are keen to explore various applications of data mining technology. With the passage of time, new data mining methods and models are constantly coming out, and the data mining technology will develop in a more promising direction, and people will study it more extensively and deeply [14]. Action education is an education that promotes the physical and mental development of individuals through the improvement of physical exercise experience and skills necessary for their development. It plays a vital role in the process of individual development and learning [15]. This paper takes aesthetic education and action education as the research object and shows that there is a close combination between physical action teaching and aesthetic education. This paper discusses the importance and function of aesthetic education in physical education and how physical education teachers educate students in aesthetic education in physical education to cultivate students’ ability to feel beauty, appreciate beauty, and create beauty. Systematically study from the aspects of theoretical level and technical framework. Realize the layer-by-layer mining from the low-level motion characteristics of action teaching to the high-level motion semantics. It not only provides support for teaching information but also provides assistant decision-making for action teaching to solve problems. In addition, several kinds of commonly used data mining algorithms are compared to analyze their calculation accuracy, which provides strong support for the selection of models in the future and at the same time deepens my in-depth understanding of these algorithms.

Reference [16] holds that the movement caused by sensory stimulation such as tactile sensation, vestibular sensation, and intrinsic sensation, which are closely related to the brain stem, can improve the functions of the brain stem and cerebral cortex, make the brain fully grow and develop, and can promote the development of individual purposeful coordinated movement ability. Literature [17] holds that the benefits of aesthetic education can be reflected not only in the external image of the individual, but also in the establishment of harmonious interpersonal relationships, the promotion of the ability to identify beauty, the resistance to corruption and feudal superstition, and the development of a good aesthetic experience and attitude. Literature [18] holds that action education develops individual perception through diversified stimulation and exercise of vision, hearing, smell, taste, touch, sense of self-orientation, sense of balance, sense of movement, and sense of time and space. Through the understanding of the language tips of the action instructor and the verbal communication with peers in action education, the development of individual verbal ability is promoted. Literature [19] points out that with the development of the times, the ideas of sports education are constantly changing and enriching, and the movement education also presents new features, showing the trend of integration. From the perspective of “meeting” between people and sports culture, this paper discusses the beauty of physical education class’s course, the value of the beauty of physical education curriculum, and the creation of the beauty of physical education curriculum [20]. Literature [21] suggests that beauty in sports is visible and tangible. It is an important way to enrich our social life and improve our aesthetic quality. Through the transcendence of aesthetic P.E. curriculum, the P.E. curriculum can leap from “physical fitness” to “physical and mental freedom” and enhance the position and function of P.E. curriculum in the education system [22]. Literature [23] pointed out that beauty neither directly comes from the object nor exists in the subject but is generated in the harmonious relationship between the subject and the object. That is to say, beauty must be a kind of homomorphism or isomorphism between the inner emotion of the subject and external things. Literature [24] suggests that in the aesthetic experience, the subject always feels that the object has a certain formal structure and emotional color and always endows them with a formal structure with emotional implication, a “meaningful form,” so that they can participate in people’s life activities.Since ancient times, aesthetic education has always been valued by people. Its unique educational functions and characteristics have attracted many philosophers and educators to study and explore. Based on previous studies, this paper puts forward a teaching method of combining aesthetic education with action education based on data mining under the background of big data. In this paper, two weak multiclassifiers based on low complexity features are connected in parallel, and then, the parallel structure is connected in series with a strong two classifiers. Finally, a strong multiclassifier with low complexity is formed to realize high accuracy and low complexity motion recognition. Experimental results show that the recognition accuracy of this algorithm is significantly improved compared with the weak classifier alone.


## 3. Methodology

### 3.1. Action Education and Its Development Trend

Action education refers to the education that promotes the harmonious development of individual’s body and mind through the improvement of physical movement skills or creative movement [25]. Action education plays an important role in promoting the healthy development of individual’s body and mind. It provides a good idea and operation method for self-exploration, understanding the body structure, adjusting the body structure, and learning the correct and efficient use of the body. Under the traditional knowledge view, sports technology is regarded as an objective, universal, and value-neutral absolute existence [26]. The study of specific sports techniques has become the core content of physical education curriculum. The responsibility of sports technology sports teachers is to impart sports technology stipulated in teaching materials to students, and sports teachers play a leading role. Students’ task is to get sports technology from teachers to the maximum extent.Action education emphasizes two points: (1) learning of movements, which includes basic athletic ability and physical ability, and (2) learn by action. Learning through actions includes the body’s exploration of the surrounding environment, the perception of motor ability and conceptualization, and the development of emotions. The key point is to enable individuals to learn how to skillfully use their bodies through the cognition of “self-body,” so as to achieve healthy and harmonious development of body and mind. The practical purpose of action education is to master action skills, treat physical and mental diseases, and promote physical and mental health. At present, the research on action education has been comprehensively analyzed from different disciplines such as kinematics, neuroscience, pedagogy, and psychology.The basic contents of motor education can be divided into motor skills, body consciousness, perception and problem-solving ability, and improvement of emotional and social skills [27]. According to the age of action education, it is divided into children’s action education, adults’ action education, and the elderly’s action education. According to the function of action education, it can be divided into therapeutic action education and developmental action education. With a clear classification, it will be convenient for us to study by classification and clarify the internal laws of action education.The course implementation process is a process of strict procedures and detailed steps, according to the traditional knowledge curriculum view. At the same time, teachers and students are presented with sports skills based on teaching materials at the start of the curriculum implementation, effectively forcing teachers and students to be loyal recipients. It is also difficult to ensure that action education runs smoothly in a school physical education class. The content of school sports action instruction is frequently monotonous, implying that it teaches only what is tested. As a result, action education’s goal is one-sided, focusing solely on individual action skill training while ignoring the harmonious development of people’s bodies and minds, resulting in a situation where action training is separated from life. Modern action education has changed the single goal of focusing only on the improvement of action skills in the past and began to pay attention to the interaction between body and mind and the construction of peripheral support system for developing individual action skills. The schematic diagram of learning level is as shown in Figure1.Figure 1
Schematic diagram of action learning level.Action education is a game, and it is a game with strong role and competition. In the game, according to the rules of action education, all participants generally have to play different roles, deal with different interpersonal relationships, and experience the value orientation provided by social interaction and game results. According to this, we can evaluate the behavior of ourselves and others in the game. In encounter learning, the teacher-student subject and motor skills are the harmonious relationship between subject and subject. Teachers and students participate in the construction of sports skills together as players. The construction process of sports skills tends to be the same as the course implementation process. It is a real game in which teachers and students play at the same time, participate together, and are not limited by sports forms. Thus, the individual knowledge of teachers and students is constantly activated in the display of sports culture and becomes the basis of new curriculum content.School physical education is one of the main forms of action education, and its main task is to enhance physical fitness, improve students’ physical and mental health, and enrich cultural life. Learners and sports culture not only expand and improve their spiritual world but also open up the possible meaning world of sports culture through dialogue understanding. People and sports culture is the infinite possibility of constantly moving towards oneself in understanding. In this sense, the teaching of motor skills based on meeting is generative, creative, and open, which affirms the unique experience of individuals and the generative and developmental nature of skills themselves. It is in this teaching process full of all kinds of possibilities that the real talents can show their lives and create their lives.


### 3.2. Combination of Aesthetic Education and Action Education

In China’s education, aesthetic education is an important part of education, and it is an education that trains the younger generation to have the ability to correctly feel beauty, appreciate beauty, and create beauty. Aesthetic purpose is mainly to cultivate students’ aesthetic tendency and improve their aesthetic ability. The significance of sports aesthetic education lies in the following: under the guidance of aesthetic sports, exerting a subtle influence on the ideological, political, and humanistic details of the educated, so as to shape sports aesthetic thoughts and good sports aesthetic tendencies. The content of sports aesthetics lies in the following: discovering the charm beauty of sports and the science of exploring its own beauty.The aesthetic education of school physical education in action education is not only the purpose of education, but also the means of cultivating and shaping all-round development talents. There are many aesthetic education factors in sports action education, and making full use of these aesthetic education factors can play a great role in sports action education. Sports action and aesthetic education are inseparable and closely related. Modern sports exude a beautiful atmosphere all the time. For example, the reason why the Olympic Games and the Asian Games can attract hundreds of millions of spectators is that they can fully display people’s speed, strength, agility, skill, and intelligence. For a long time, sports action education has paid more attention to the role of bodybuilding and strengthening. Even if we pay attention to its multifunctional value, we seldom know it from the perspective of aesthetic education. How to integrate aesthetic education into sports action education, so as to effectively cultivate students’ aesthetic ability, is a topic worthy of study.There is a close relationship between the aesthetic structure and people’s physical structure, which makes it possible for aesthetic education and action education to blend perfectly and organically. Aesthetic education and sports action education are indispensable in modern education. Together with moral education and intellectual education, they constitute an important element of a person’s all-round development. Teachers and students should master sports skills and impart sports knowledge. On the one hand, they should use concise and accurate language and perfect correct demonstration actions to impart sports knowledge. Simultaneously, students should never be able to master the correct technology, which has aesthetic value in and of itself. On the other hand, it is also the process and law of aesthetic education to avoid instilling in students incorrect, graceful, and incorrect movements that are out of step with their physical development, as well as inaccurate and unprofessional terms. Aesthetic education is built on the foundation of physical education. People’s physical structure has a direct impact on and improves the healthy development of their aesthetic psychology. It is conducive to the good development of the brain and the enhancement of sensory ability through sports action education. Aesthetic education is built on a foundation of sensitive sensory activity and rich brain activity. As a result, aesthetic education and sports action education are inextricably linked. The former is constantly improving psychology’s physiological foundation, whereas the latter is perfecting the psychological structure of beauty based on physiology and promoting the realization of ideal personality.The fundamental purpose of sports education is to strengthen people’s physique, and strong physique is expressed through bodybuilding, so the process of physical education is also the process of establishing the form of pod, and the establishment of the form of beauty cannot be separated from the perception and judgment of beauty and the pursuit of beauty. Students’ pursuit of beauty in sports teaching activities is also strong. Students’ pursuit of beauty is manifested in many aspects, and they also have their own aesthetic ability. For example, in the process of receiving knowledge, through brain activities, we can discard incorrect movements and maintain beautiful and correct movements, which is the process of gradual formation of aesthetic ability. Aesthetic ability is also a form of intellectual activity. Aesthetic education in sports action education can enhance students’ concept and consciousness of beauty, improve their aesthetic ability, enable students to acquire the beauty of action, technology, strength, form, harmony, and various aesthetic feelings in sports, and stimulate students’ interest in sports action education. Improve students’ sports ability, and at the same time make students enjoy beauty. The action flow is shown in Figure2.Figure 2
Action recognition process.Compared with teachers of other disciplines, sports teachers should pay more attention to the artistry of language explanation by words and deeds. Intuitive demonstration actions should be accurate and should be easy and graceful on the basis of accuracy, so as to play an intuitive role for students to master technology. At the same time, it can also make students interested in the technical movements they have learned. The choice of teaching means should be novel, diverse, and colorful. Be targeted, scientific, and interesting. Action courses should be carefully designed, and they need to be changed frequently, with various forms. The action arrangement of preparation activities should be colorful, constantly changing, and new, so that students can never tire of learning, and always keep a high learning enthusiasm, so as to improve students’ ability to feel beauty, appreciate beauty, and express beauty.


### 3.3. Aesthetic Education and Action Education Teaching Based on Data Mining

There are many technologies of data mining, and there are different classifications according to different classifications. Generally, it can be divided into supervised algorithms and unsupervised algorithms, among which supervised algorithms mainly include logical regression and decision tree. Unsupervised learning mainly includes clustering, nearest distance, and support vector machine.Sports aesthetic tendency mainly consists of three parts: sports aesthetic attitude, sports aesthetic experience, and sports aesthetic ability. On the aesthetic attitude of sports, college students are trained by aesthetic education to cultivate their aesthetic tendency of sports, and their aesthetic cognition of sports itself is further enhanced, which increases students’ emotions related to sports activities and produces their participation experience of sports behavior or exercise activities. Teachers play a very important role in curriculum implementation. In a sense, curriculum plans are finally implemented through teachers’ teaching plans. The “teaching” of physical education teachers is mainly manifested in the reorganization of sports forms in the implementation of the course of meeting. Motion features are equivalent to descriptors of human movements, and the expressive ability of features to identify targets largely determines the final recognition effect, so researchers try to express human movements with various efficient features.Standardize the gray image’s pixel space, specifically using the Gamma compression method to reduce noise even more, and perform contrast adjustment at the same time, making features more resilient to local light and dark changes in the image. The following is the compression formula:(1)Ix,y=Ix,ygamma,in whichIx,y represents the pixel value of the pixel point x,y. For each pixel in the image, the gradient amplitude and direction are calculated, respectively, and the contour information of motion is captured. The formula is as follows:
(2)Gxx,y=Ix+1,y‐Ix‐1,y,Gyx,y=Ix,y+1‐Ix,y‐1,whereGxx,y and Gyx,y, respectively, represent the horizontal gradient and vertical gradient at the pixel point x,y, and the magnitude and direction of the ladder x degrees at this point are as follows:
(3)Gxx,y=Gxx,y2+Gyx,y2,αx,y=arctanGyx,yGxx,y.The quality of data is the precondition of the prediction result, and data preprocessing is the preparation of data prior to data mining. Extract the corresponding image features after preprocessing the projected image. The height and motion range of the target will affect the features for different people doing the same action. To reduce intraclass variation, the projected image must be standardized, that is, only the foreground target must be retained, the interest boundary box must be established based on the target, and the target image must finally be fixed to a unified image scale. Assume that the position of the elliptical candidate target frame in the new image isθ, and the shape is defined by covariance matrix V. The color histogram defines the color appearance characteristics rθ,V of the candidate target frame area. The value of the m-th color interval is calculated by formula (4).
(4)rmθ;V=∑i=1NvNxi;θ;Vδbxi−m.The similarity between the candidate target and the actual target is determined by the similarity of their histograms. In this paper, Bhattacharyya coefficient is used to measure the similarity of two histograms, and the calculation formula is as follows.(5)ρrθ,V,o=∑m=1Mrmθ,Vom.The first-order Taylor series expansion of the current estimated valuerθk,Vk is obtained.
(6)ρrθ,V,o≈c1+c2∑i=1Nvω1Nxi;θ,V.Among them,c1 and c2 are constants, and the calculation formula of ωi is as follows:
(7)ωi=∑m=1Momrmθk,Vkδbxi−m.To maximize the Bhattacharyya coefficient, that is, the candidate target is most similar to the target simulation, the second term in Equation (7) should be maximized. This process can be achieved by means of a mean shift algorithm.A relatively advanced background model is constructed by using the statistical features of a certain pixel or a group of pixels in the image to obtain the background image, and the background model is updated with the dynamic changes of the scene. The motion features based on human joint information can more intuitively reflect some motion information, such as motion speed, acceleration, and joint motion trajectory, when compared to the human motion features extracted from the depth map. At the same time, because the three-dimensional position information is not limited by factors like light intensity or resolution, and the camera shooting angle has no effect on it, its features can compensate for the lack of depth map motion features. Because the contour method relies on edge information to describe the contour, using the contour method to extract moving objects can partially solve the “hole” problem. This method can achieve better detection results as long as there are obvious edge features.

(7)ωi=∑m=1Momrmθk,Vkδbxi−m.To maximize the Bhattacharyya coefficient, that is, the candidate target is most similar to the target simulation, the second term in Equation (7) should be maximized. This process can be achieved by means of a mean shift algorithm.A relatively advanced background model is constructed by using the statistical features of a certain pixel or a group of pixels in the image to obtain the background image, and the background model is updated with the dynamic changes of the scene. The motion features based on human joint information can more intuitively reflect some motion information, such as motion speed, acceleration, and joint motion trajectory, when compared to the human motion features extracted from the depth map. At the same time, because the three-dimensional position information is not limited by factors like light intensity or resolution, and the camera shooting angle has no effect on it, its features can compensate for the lack of depth map motion features. Because the contour method relies on edge information to describe the contour, using the contour method to extract moving objects can partially solve the “hole” problem. This method can achieve better detection results as long as there are obvious edge features.


## 4. Result Analysis and Discussion

Classification and prediction are two different forms of data analysis in data mining, which can be used to extract data classes that people are interested in and can also be used to predict the development trend of future data. This is an instructive learning process. In the recognition process, the hybrid joint feature recognition algorithm needs to go through two steps: multiclassifier recognition and two-classifier selection. During the multiclassification period, depth features and joint information features are used to identify and compare, respectively, while two classifiers cannot adopt the same features as the front-end ones for the fairness of preferential selection. Therefore, two kinds of joint information features are selected as feature vectors of multiclassifier and dual classifier, respectively. By means of questionnaire survey, the aesthetic data of students’ sports actions are obtained. The results of the aesthetic questionnaire of students’ sports movements are statistically analyzed by general descriptive analysis, and the results are shown in Figure3.Figure 3
Basic data of sports aesthetic factors.From Figure3, it shows that students have strong sports action appreciation ability, strong aesthetic pursuit of sports action, and deep empathy in sports. It can be seen that Chinese contemporary teenagers are sensitive to the beauty of sports.There may be some data in the database that deviates from normal behavior or characteristics, which will affect our analysis results, usually called outliers. In most cases, these outliers will be ignored and discarded as noise or abnormal data. However, in some cases, these outliers may contain interesting knowledge which is impossible for normal data. Nonimage human motion recognition usually needs to consider extracting time feature information and spatial feature information. Among the features based on joint point position information, spatial feature information can be obtained directly from joint point position information, while time feature information mainly depends on the motion track of each joint point. Therefore, studying the frequency feature of joint point motion track is also one of the methods to study time feature information. For pattern mining, using the geometric information of the corrected trajectory, we mainly dig out some preliminary structured information in the video, as well as the sports habit problems based on statistics. For event detection, the geometric information and semantic information of the corrected trajectory are used to jointly mine out more accurate structured information in the video. For knowledge mining, the results of pattern mining and event detection are used for statistical analysis to obtain interested knowledge. At the same time, other technical means can be used to obtain the success rate of athletes in the first round, so as to obtain the corresponding implicit knowledge. Figure4 shows the particle weight evaluation based on data mining.Figure 4
Particle weight multiple evaluation based on data mining.After each tracking iteration is completed, the person areas in the current video frame are obtained, and each person area is identified by the classifier in person detection. In order to simplify the tracking algorithm, some additional constraints are often imposed on the shape or movement process of the target object. For example, most tracking algorithms are based on the assumption that the moving target is smooth rather than arbitrarily changing in the movement process, and the moving target is uniform or has uniform acceleration in the movement process. In addition, if we can make full use of the prior knowledge of the shape, size, and color of the moving target in the tracking process, the tracking task can be greatly simplified.Assign the current split node to the node with the highest information gain, which will reduce the amount of data required when the tree structure is finally generated and the training samples are divided. This is a crucial step in problem matching because specific features must be chosen for specific problem types. If there are too many feature choices, on the one hand, motion mining efficiency will suffer; on the other hand, it may have a negative impact, resulting in mined knowledge deviating from the real situation; if the feature selection is too small, the required knowledge will not be mined, or there will be insufficient knowledge to meet the user’s needs. Figure5 is an experimental result diagram of the weight factor α parameter.Figure 5
Experimental result diagram of weight factorα parameter.Experiments show that the effect is the best whenα is 0.9. In most cases, we cannot make any assumptions about the distribution of real data. In addition, limited mathematical formulas cannot describe all the situations in the real world. At this time, the machine learning method shows its unique advantages. It does not need any restrictions on data, and it is often more accurate than the classical methods. In this paper, the initial tracking window is obtained by time difference method. A mechanism for detecting tracking loss and correcting it in time is proposed to ensure the real-time and effectiveness of target tracking. Covariance features can well reflect the related information between joints in the process of human motion. For different movements, these correlations are mainly reflected in the relative motion and coordination between joints. Figure 6 is a comparison chart of the relationship between the recognition rate and the number of classifiers before and after mining.Figure 6
Comparison chart of relationship between recognition rate and classifier number before and after mining.The classifier excavated in the figure above is obviously superior in the segment with high recognition accuracy rate, and the segment with low recognition accuracy rate is obviously less than that calculated by using all joints, so it can better meet the needs of the lifting structure. Setting the tracking window in the target area determined by motion detection as the criterion for accurately tracking the target, using the accumulator to solve the camera jitter problem, and updating the tracking target in real time, even if the tracking is lost due to camera jitter or scene switching, the initial window can be automatically adjusted to ensure accurate tracking in the future. Kinematics information describing human movements can consider velocity and acceleration variables, which are vector variables and can distinguish the direction of joint movement. Experiments show that the covariance matrix obtained by using velocity and acceleration information at the same time does not significantly enhance the effect of motion recognition compared with only increasing velocity information. Compared with increasing the amount of calculation by half, the increase of recognition rate brought by acceleration information is very low in cost performance. Therefore, the speed information is increased, and the discrimination of some complex actions is improved. Sample set is extracted for the experiment, and the recognition rate curve of the first n frames of the sequence is shown in Figure7.Figure 7
Recognition rate curve of the first n frames of the sequence.It is primarily based on the definition of the problems for matching algorithm results and problems and then comparing them one by one. The patterns or events have occurred if the rules of the results match the definition of the problems; otherwise, they have not. The main idea behind pattern mining based on motion is to mine motion using the geometric features of the modified trajectory. The geometric features of the trajectory are similar in many cases, but this does not always imply that the implied information is consistent. As a result, it is necessary to consider the semantic information of the trajectory in its entirety. Useful and interesting information cannot be obtained directly after obtaining the basic features to form the feature database, and knowledge can only be formed after some processing, which can help people find interesting content, meet the requirements of seamless consumption, and provide information. Predict the four aspects of students’ aesthetic movement tendencies, and you will get the results in Figure8.Figure 8
Students’ aesthetic tendency of action changes.It can be seen from Figure8 that the predicted value of sports skill mastery is the best, followed by the better sports time and frequency, and the weaker predicted value of sports intensity, which shows that the explicit behavioral influence of sports aesthetic tendency on sports skill mastery is more prominent. In the matching matrix, any feature vector of the matching action sequence has a matching relationship with all feature vectors in the template action sequence, so the matching matrix contains all matching paths, and the shortest of these paths is the final matching path.Taking the beauty of sports learning as the core category of aesthetic research of physical education curriculum, this paper extends the learning of sports skills to the meaningful relationship between people and sports culture, outlines the premise, conditions, and possible ways to realize the freedom of sports learning, and concludes that the beauty of sports learning lies in “the encounter between people and sports culture.” The teaching research of combining aesthetic education with action education based on data mining provides us with a new idea. A pattern mining method based on motion is proposed, that is, data analysis is carried out on the basis of the corrected trajectory, and the geometric features of the corrected trajectory are used for motion mining. In the experiment of single action recognition, we will mainly verify the recognition rate improvement brought by parameter training, back-end two-classifier training of hybrid-parallel mechanism, and the whole lifting framework to ensure the effectiveness and feasibility of the algorithm framework. Experiments show that the data mining algorithm in this paper can greatly reduce the number of joint points involved in the operation and reduce the algorithm complexity of extracting Fourier time pyramid features. It can improve the classification accuracy to meet the structural requirements and lay the foundation for improving the classification model recognition accuracy of actions.


## 5. Conclusions

As a conscious existence, sports course can be examined, described, or defined from different angles. Exploring the physical education curriculum from the perspective of aesthetics is obviously different from exploring the physical education curriculum from the perspectives of epistemology, ethics, psychology, and sociology. There are beauty factors everywhere in sports. Paying attention to the role of aesthetic education in physical education teaching can not only improve students’ aesthetic ability but also enhance students’ interest in sports, exercise enthusiasm, and improve exercise effect. Schools should combine “body” with “beauty” to promote the generation of students’ sports aesthetic tendency and form good sports aesthetic attitude, experience, and ability in sports aesthetic activities, so that the number of students who reach the “excellent and good” level of sports aesthetic tendency evaluation scale will increase. As a physical education teacher, we should strengthen aesthetic cultivation, actively explore and develop aesthetic materials in physical education, and incorporate aesthetic education into physical education, so as to cultivate students’ physical beauty, sports beauty, and life beauty and improve their aesthetic, beauty-loving, and beauty-creating abilities. While teachers make aesthetic diagnosis and interpretation of sports skills, students should make “aesthetic experience reverie” about the learning of sports skills. Aesthetic education and action education are new topics related to pedagogy, psychology, aesthetics, and physical education. It needs further discussion in theory, and it needs to be enriched and tested in teaching practice. The theoretical construction of action education will be an important aspect of the research and development of this discipline. Although there is little knowledge and research on action education in China at present, however, with the changes of the times and the deepening of people’s understanding of action education, the research and development of action education in China will be flourishing.
