Introduction
For data research or data application requirements, data visualization is to present speci c data in the form of statistical charts and information. Big data analytics refers to the process of extracting potentially valuable information from a large amount of noisy and incidentally incomplete application data [1]. Big data analytics is a poorly multidisciplinary methodology. e main areas are neural networks, pattern recognition, spatial data analysis, image databases, signal processing, arti cial intelligence, knowledge base systems, data acquisition, and bioinformatics heuristic algorithm. e KMC algorithm is widely used in data statistics, data analysis, and machine analysis due to its short and fast properties [7]. e KMC method based on heuristic algorithm shows significant advantages in smalland medium-scale data analysis. However, when the largescale data sets are clustered, it is necessary to manually determine the number of clusters, the clustering results are unstable, and the misselecting noise and abnormal points will eventually lead to inefficient data processing and poor clustering quality [8].
e data analysis process is based on a large amount of data, and the ability of human brain to absorb and process information is limited. Visualization technology can transform scientific data into graphic image information that changes with time and space through computer and image processing technology and finally achieve the interactivity, visibility, and multidimensionality of the data [9]. Researchers can analyze the data and its changing trends through graphs and images. Data visualization speeds up data processing and increases the utilization of effective data. Data visualization has been widely used in various fields such as natural sciences, engineering technology, finance, communications, and commerce [10]. Basketball has become a popular sport because of its features such as simplicity, fun, fitness, and education. e depth of basketball is measured by the game. Basketball statistics can make an objective analysis of the data and unearth potential actual combat information. However, there are few studies on applying cluster analysis methods to basketball big data analysis.
In summary, the KMC method based on heuristic algorithm for processing big data has to be further optimized, and there is limited research on applying the clustering data analysis method to basketball data analysis. In this study, the KMC algorithm in the heuristic method is optimized and applied to basketball big data analysis to provide a reference for basketball big data clustering and visual management.

e Cluster Analysis Methods of Big Data.
Big data cluster analysis is the process of grouping a collection of physical or abstract objects into multiple classes composed of similar objects, clustering a collection of data objects in the same cluster. Big data analysis is not a postprocess that obtains effective results after simple analysis of input data. It needs to go through the continuous repetition of a multistep complex process to obtain accurate results. For n vectors in the a-dimensional space Ra, they are assigned to one of the c clusters, so that the distance between each vector and its cluster center is the smallest. en, the distance between the vectors X i and X j can be expressed as follows: Cluster analysis mainly includes two kinds of data matrix and discrepancy matrix [11]. ey differ from the matrix diagram method in that they are not filled with symbols on the matrix diagram but filled with data to form a matrix for analyzing the data. e data matrix is a matrix in which d data objects of the entire data set are described with l attributes, and the final data object set is regarded as a d * l matrix. e data matrix can be expressed as follows: e difference matrix refers to the degree of similarity between any two data points in the overall data object set [12], which can be expressed as follows: In (3), n represents the number of data points, and the d(i, j) in the matrix represents the difference degree calculated according to the specified degree of similarity of the data points i and j in the data object collection. e larger the d(i, j) value, the greater the degree of difference between the data objects. e core of cluster analysis is to obtain the degree of similarity among different data objects [13]. At present, the Minkowski distance calculation method, the Euclidean distance calculation method, and the Chebyshev distance calculation method are commonly used for evaluation [14]. Among them, the data obtained by the Euclidean distance calculation method is not affected by coordinate translation and rotation changes, and it is a commonly used distance similarity measurement method [15]. e calculation method of Euclidean distance is given as follows: In the above equation (4), d(i, j) represents the Euclidean distance between two data points, which satisfies the con- e similarity factor is mainly used to gauge the similarity among data points [16]. e angle cosine method is a commonly used similarity coefficient calculation method. e value range of the similarity coefficient is [−1, 1]. When the orthogonal value is 0, it means that the two vectors are completely dissimilar. e calculation method of the similarity coefficient of the angle cosine method is as follows: (5) e correlation coefficient method represents the degree of correlation between two data vectors [17], and its value range is [−1, 1]. 0 means that they are not correlated, 1 means that positive correlation is found, and −1 means that negative correlation can be seen. e correlation coefficient method can be expressed as follows: Appropriate criterion function in cluster analysis can further improve the quality of clustering [18]. e criterion functions commonly used in cluster analysis are as follows: squared margin of error, squared weighted mean value distance sum, and interclass distance sum [19]. e error sum of squares is often used for data analysis with dense samples and little difference between samples [20]. e error sum of square (J a ) can be expressed as follows: In the equation above, m j is the average value of the class C k , and m j � (1/n j ) n j i�1 x i . nj refers to the number of objects in the class C k . e interclass distance and criterion (J b ) calculates the distance sum of every clustering epicenter to the global epicenter. e higher the similarity of the research data, the less obvious the clustering result, and the results making J b the largest result have to be found.
e weighted average squared distance (J c ) is applicable to data objects with a large disparity in the number of samples, and its calculation method can be expressed as follows: In the above two equations, s * j refers to the average squared distance between samples within a class, and P j is the prior probability.

Establishment of Cluster Analysis Method Based on
Metaheuristic Algorithm. KMC is the most classic and most widely used clustering method in the metaheuristic algorithm. e kinetic Monte Carlo method (KMC) is simple in principle and highly adaptable, so it is the first choice of researchers in many cases.
is method takes Euclidean distance as the correlation measure, and the error sum of squares criterion (J a ) as the criterion function to minimize the evaluation index. e KMC algorithm divides the data set A into the closest classes, and its cluster center is C 1 , C 2 , C 3 , . . . , C k . e calculation method of each cluster center point is shown in equation (11), in which i � 1, 2, . . . , k and n i was the number of data objects in the class C i .
e traditional KMC method has a great dependence on the selection of the initial clustering center point, and it is susceptible to the interference of local noise data. e different feature weights assigned to the attributes of each data point can improve the KMC results greatly. e feature weights of variable patterns were assigned to data points, which were named KMC based on density, DK-Mean. e attribute feature weight value of the j-th dimension is assigned to the object data. e calculation method is expressed as follows: In (11), a j is the ratio of the distance between the classes of the attribute and the distance within the classes, and a j � d b /d i (d b refers to the distance between classes, and d b � K k�1 (m kj − m j ) 2 ; d i refers to the distance within the class, and d i � K k�1 n k i�1 (x ij − m kj ) 2 ). m i represents the mean value of the data set on the j-th dimension attribute; K is the number of clusters, and j is the number of attribute bits. en, the weighted Euclidean distance calculation equation can be written as follows: e KMC method relies on the cluster center point, which is easy to cause local optimal clustering. Based on the density, the choice of the original aggregation centers is improved accordingly in this study. e clustering criterion function can be denoted as the following equation: In (13), k wi represents the distance within the class, and k wi � max i∈ [1,k] min j∈ [1,C i en, the density D(x) at sample point X can be expressed as the following equation: In (14), D i represents the weighted Euclidean distance, and r is the specified radius.
Cluster analysis method can solve such problems; cluster analysis method is an exploratory analysis method, which can analyze the inherent characteristics and laws of things and is a commonly used technology in data mining. Genetic algorithm shows good applicability and scalability and can reduce the initialization requirements of traditional clustering algorithms in cluster analysis. e genetic algorithm is introduced further based on the DK-Mean algorithm to increase the accuracy of the clustering algorithm in this study.
e genetic algorithm search can minimize the J k value, and then the fitness feature can be represented as formula (16): e probability of an individual being selected can be expressed as follows: In the above equation, f(x i ) is the fitness value, and i � 1, 2, . . . , p s . e crossover operation is performed on two individuals x 1 , and x 2 , and the new individuals produced by them can be expressed as equations (18)∼ (19), in which α is the uniform arithmetic crossover parameter.
e improved DK-Mean algorithm calculates the data gap matrix and initializes the target eigenvalues to obtain new cluster centers. e specific process of the DK-Mean algorithm is shown in Figure 1.  process of visualizing data for business simulation, correlating multidimensional business data to form a more comprehensive data result, and providing users with auxiliary decision-making process, which is called visual analysis. Parallel coordinate method has the characteristics of mapping high-dimensional data to low-dimensional space and can interact with users at the same time, and it is a commonly used method of visual data analysis at present. In this study, a visual data analysis model based on the KMC algorithm is established based on the optimized KMC algorithm and the parallel coordinate method. It is assumed that G is a collection of n-dimensional data objects, and G � g 1 , g 2 , . . . , g n , of which gi is an n-dimensional collection g i � x i1 , x i2 , . . . , x in ; the basic coordinate axis x 1 , x 2 , . . . , x n corresponds to the attribute of the i-th dimension, and each n-dimensional vector can be expressed as H h 1 , h 2 , . . . , h n . e polyline H of the n-dimensional data using linearly independent equations is given as follows:

Visual Data Analysis and Visualization
According to the mapping principle from the midpoint of the coordinate system to the parallel coordinate, the following equation can be obtained: In the equation, m i is the slope, and b i represents the intercept on the axis in parallel coordinates x i+1 . e technology and process of data analysis are applied in the basketball data visualization management system, which can be data processing automation. e data analysis visualization process based on the optimized KMC algorithm is shown in Figure 2. After the sample data is processed through selection operations and cross operations, a new visualization population can be formed.

e Evaluation Indicators of Cluster Validity.
e main indicators in the cluster analysis evaluation are as follows: Accuracy, Precision, Recall, and F1 value, four commonly used indicators. e ideal clustering result should reflect the internal structure of the data set as much as possible, so that the sample similarity between classes is the smallest, and the samples within the class are the most similar. In this study, the Between-Within Proportion (BWP) and improved BWP (IBWP) indicators were adopted to analyze the clustering results and performance, where BWP is the ratio of the clustering deviation distance to the clustering distance, and its calculation method is given as follows: In the equation, c(i, j) represents the interclass distance of the object i in the j-th class, and c(i, j) represents the intraclass distance of the object i in the j-th class. Among them, n is the number of data objects, which can be the number of divided clusters, n a represents the number of elements of the class a, and j represents the class label. e larger the BWP(i, j) value, the more effective the clustering of sample objects. e IBWP indicators can evaluate the clustering effectiveness of a single data object very well, and its calculation method is shown as follows: In the (21), ic(i, j) and iw(i, j)represent the interclass distance and the intraclass distance of the object i in the j-th class. e larger the value of IBWP index, the more effective the clustering of individual points of the sample. e speedup ratio and the expansion rate are used to evaluate the parallelization effect and performance of the e calculation method of speedup ratio and the expansion rate is given as follows: In the above two equations, T 1 is the data processing time for a single node; T m is the data processing time for m nodes. N is the size of the processed data; T n is the time for data to be processed on a child node; and T mn is the time for data of size n to be processed on m nodes.

In this study, the IRIS, WINE, SEED, ABALONE, LETTER, and COVTYPE data sets in the UCI database are undertaken as the validation sets to verify the algorithm model established. Table 1 shows the total number of samples, dimensions, and categories of the data set.

e NBA shooting guards in the 2018-2019 season were selected as the research objects. e relevant indicators included in the study were analyzed statistically using literature data method, logical analysis method, mathematical statistics method, video analysis method, and comparative analysis method. e technical statistical data of the season finals are collected on related websites such as Tencent Sports Video, Hupu NBA, the control video, and official statistics, which were repeatedly confirmed to ensure the authenticity and reliability of the data source. ese raw data were adopted for statistical analysis of basketball technical indicators. Data analytics can help businesses better understand their customers, improve their advertising campaigns, personalize their content, and improve their bottom line.

Analysis on Influencing Factors of Basketball Scoring Based on KMC Algorithm.
e 2018-2019 season NBA scoring guards were selected as the research objects. Based on the NBA data query website (https://www.basketball-reference. com/), 17 basic pieces of data such as player scores, rebounds, assists, and steals, as well as advanced data such as passing ability, defensive contribution, and offensive contribution are selected as the original data. e original data removes rebounds, blocks, and fouls and reduces the original data from 36 dimensions to 22 dimensions, including Field goal attempts (FGA), Field goals (FG), Free throws (FT), Free throw attempts (FTA), Assists (AST), Steals (STL), and Points (PTS).

Analysis on Results Based on Metaheuristic Clustering.
Using the traditional KMC algorithm to cluster the data in the IRIS data set, the clustering results are divided into 4 clusters, but the clustering results of some data overlap (Figure 3(a)), and the clustering results are significantly different from the real data. e optimized KMC algorithm is used to cluster the data in the IRIS data set. e clustering results are divided into 4 clusters, the data clustering results are of high quality, and there is no crossover phenomenon of different types of data (Figure 3(b)). In addition, there is no difference between the clustering results and the real data.

Comparison on Classification Indicators of Different Clustering Algorithms.
e traditional KMC algorithm is compared with DKMC, the optimized KMC algorithm, selforganizing feature map (SOM) algorithm, quantum evolutionary clustering algorithm (QEAM), and k-medoids algorithm in terms of BWP values (Figure 4(a)). As the number of clusters increases, the BWP values of different algorithms show a downward trend all, and the number of clusters increased from 2 to 16. After optimization, the BWP value of the KMC algorithm only drops by 0.35, which is the smallest drop among all algorithms. e BWP value of an optimized KMC algorithm with the same number of clusters is higher than that of other algorithms. e IBWP values of the different algorithms are compared, and the results are shown in Figure 4(b). As shown in the figure, the IBWP values of the various algorithms show a decreasing trend as the number of clusters increases. e number of clusters increases from 2 to 16. After optimization, the IBWP value of the KMC algorithm only decreases by 0.288, which is the smallest decrease of all algorithms. e IBWP value of an optimized KMC algorithm with the same number of clusters is higher than that of other algorithms.

Execution Time of Clustering Algorithm.
e optimized KMC algorithm was used to perform cluster analysis for six datasets in the UCI database ( Figure 5). As the number of nodes increases, the time taken by the KMC algorithm to collect 6 different data sets decreases. If the number of nodes is 4, the COVTYPE dataset output time is 1922 s, and the IRIS dataset output time is 113 s.

Performance Analysis of Clustering Algorithm in Parallel Data Processing.
e speed ratios of the optimized KMC algorithm between the six data sets were analyzed and  Figure 6(a). As the number of parallel nodes increases, the speed ratio of the KMC 6 algorithm when processing the data set shows an increasing trend. If the number of parallel nodes is 10, the maximum speed ratio of the COVTYPE data set is 4.16. e expansion ratios of the KMC-optimized algorithm between the six data sets were analyzed and compared, and the comparison results are shown in Figure 6(b). As the number of parallel nodes increases, the expansion ratio of the KMC algorithm for processing the six data sets appears to decrease. If the number of parallel nodes is 10, the maximum expansion ratio of the COVTYPE data set is 0.81.

After optimization, the accuracy of the KMC algorithm when processing the six data sets was clearly higher than the other two algorithms (P < 0.05). e convergence times of the different clustering algorithms in the different data sets are compared, and the results are shown in Figure 7(b). e convergence time of the optimized KMC algorithm in the different data sets was shorter than that of the other algorithms, and the difference was statistically significant (P < 0.05). e number  Figure 7(c). e number of iterations of the optimized KMC algorithm across the different data sets was lower than that of the other algorithms, and the difference was statistically significant (P < 0.05).As the convergence time increases, different clustering algorithms are proportional to the data iteration effect.

Analysis on Cluster Visualization Result.
e traditional KMC algorithm and the optimized KMC algorithm are performed with the cluster analysis on the Luanweihua data set in the IRIS data set. e cluster visualization analysis is performed on three types of Luanweihua data in this study. After cluster analysis, all data are divided into 3 clusters, with 50 groups of data in each cluster of original data. After clustering using the traditional KMC algorithm, a total of 16 sets of data have been misclassified, and the clustering accuracy is 89.33%, as illustrated in Figure 8. After clustering using the optimized KMC algorithm, there are two sets of data that are misclassified, and the clustering accuracy is 98.67% (as given in Figure 9). rough the clustering visualization analysis of the traditional KMC algorithm, the   Mobile Information Systems traditional KMC clustering accuracy is about 10% lower than that of the optimized KMC.

Analysis on the Statistic Results of Basketball Technical
Indicators. According to the data from the NBA official website, the technical indicators of the top 10 Eastern teams in the 82 regular seasons in the 2018-2019 season are counted, and the results are shown in Figure 10. e figure illustrates that, except for the significant differences between the lost points and the score items, there is little difference in other indicators. e field goal score of Indiana Pacers is 25.4, which is lower than the first place (Milwaukee Bucks, 38.2 scores), showing a difference of 12.8 between the two. e comparison on the indicators of the first and tenth teams shows that the scores for shots, hits, and rebounds of Milwaukee Bucks are 5.8, 2.8, and 3.4 higher than those of the Miami Heat. e technical indicators of the top 10 Midwestern teams in 82 regular season games are compared, and the results are given in Figure 11. e free throw of Houston Rockets is as high as 45.4, which is obviously higher than that of other teams. e scores in rebounds and assists of Los Angeles Clippers are 22.6 and 28.5, respectively, which are much higher than those of other teams. e shooting percentage of Los Angeles Lakers (the 10th) is 0.7, which is much lower than that of the San Antonio Spurs (0.82) and the Golden State Warriors (0.8).
A cluster analysis is performed in 20 teams in regular games (Figure 12), which shows that 20 teams in the East and West are clustered into 7 categories. Among them, the Golden State Warriors and the Milwaukee Bucks, the first place in the East and West teams, are grouped into the same category. It shows that the top NBA teams have similar characteristics to a certain extent. e technical indicators of the Golden State Warriors and the Milwaukee Bucks team in the East and West teams are compared, as given in Figure 13. e scores in shooting, attempts, free throws, rebounds, assists, and blocks of the Golden State Warriors and the Milwaukee Bucks are higher than the average scores of all teams. e Milwaukee Bucks and the Golden State Warriors have rebound scores of 49.8 and 46.2, respectively, which are higher 4.6 points and 1 point than the average scores of all teams, respectively, which shows that the rebounding technical indicators of the Milwaukee Bucks have a significant advantage. e scores in assists of the Milwaukee Bucks and the Golden State  Warriors were 26 and 29.4, respectively, showing that the score in assists of the Golden State Warriors has a significant advantage.

Analysis on the Result of the Influencing Factors of Basketball
Scoring. e coefficients of the NBA basketball score scheme in the different groups were compared based on the optimized KMC algorithm. As shown in Figure 14, the cluster boundary factor first increases and then decreases as the number of clusters increases. If the number of clusters is 7, the cluster boundary factor reaches a maximum value of 0.24.
Based on the optimized KMC algorithm, the functional factors of basketball NBA scores are analyzed, and the matrix of different factors after coordinate translation is shown in Table 2. All factor coefficients are close to 0 or 1. e influencing factors of basketball NBA score are analyzed based on the optimized KMC algorithm, and the distribution of different factor cluster centers is shown in Figure 15. e leader factor, offensive contribution factor, shooting stability factor, and passing ability factor in the absolute core grouping are all the maximum values, which are 0.59, 0.51, 0.47, and 0.43, respectively.

Discussion
In this study, the KMC algorithm in the metaheuristic clustering method is optimized, its clustering and visualization performance are analyzed, and it is applied to the analysis of basketball NBA score functional factors. It is found that the clustering results of traditional KMC algorithm have the overlapping of some data clustering results,   and there is a big difference with the real data. e optimized KMC algorithm does not have the crossover phenomenon of different types of data, and the clustering results are closer to the real data. Such results prove that the optimized KMC algorithm shows improved quality of clustering results. e clustering centers of the traditional KMC algorithm are randomly selected, which leads to errors in the clustering results, and the clustering analysis of the traditional KMC algorithm requires multiple iterations, so the clustering results are greatly different from the true data distribution. e optimized KMC algorithm has coordinate rotation to select the cluster center, which reduces its randomness, so the initial cluster center can be determined more accurately. e number of clusters increased from 2 to 16. After optimization, the BWP value of the KMC algorithm only drops by 0.35, and the IBWP value only drops by 0.288, which is the smallest drop of all algorithms. Such results suggest that the optimized KMC algorithm shows better clustering results. e BWP and IBWP values of the optimized KMC algorithm are greater than those of other algorithms, indicating that the optimized KMC algorithm shows higher clustering accuracy on the samples. As the number of nodes increases, the time for the KMC algorithm to cluster 6 different data sets shows a downward trend. When the number of nodes is 4, the optimized KMC algorithm can process the COVTYPE data set for a maximum of 1922 s, and the shortest running time for processing the IRIS data set is 113 s. e sample size of the IRIS dataset is observably lower than that of the COVTYPE dataset. Such results indicate that the optimized KMC algorithm takes longer time to process low sample size data. is is because each operation needs to start the Map and Reduce tasks, which takes a certain amount of time, so when the task start time dominates, the small samples are processed. Xu pointed out that as the number of sample nodes increases, the running time of clustering decreases. e larger the data size, the better the acceleration ratio of the algorithm, and the better the algorithm's ability to handle large data. If the number of parallel nodes is 10, the maximum speed ratio of the KMC algorithm optimized for processing the COVTYPE data set is 4.16. He found that the optimized KMC algorithm has several advantages in big data processing. As the number of parallel nodes increases, the level of expansion of the KMC algorithm for processing the six datasets appears to decrease. If the number of parallel nodes is 10, the maximum expansion rate of the COVTYPE data set is 0.81. is is because the amount of communication between each node increases as the number of nodes increases. Some studies have shown that as data size increases, parallel uptime increases, which is similar to the results of this study. is is because the optimized KMC algorithm introduces weights in the calculation of the Euclidean distance, which increases the Euclidean distance between the abnormal point and the cluster center and makes the algorithm iteration result closer to the real data, thereby reducing the number of iterations and  convergence time and improving clustering accuracy. Yin pointed out that the optimized KMC algorithm has improved the clustering efficiency, and its clustering accuracy has not changed greatly. e reason is that the study did not consider the impact of each sample data on the entire clustering result, so the Euclidean distance calculation method was not optimized. e clustering accuracy of the traditional KMC algorithm is 89.33%. After optimization, the clustering accuracy of the KMC algorithm is 98.67%, and the clustering accuracy is improved by 9.34%.
Effective clustering can correctly display the player's status, which is helpful for the rational operation of the team.
e research results of this study show that as the number of clusters increases, the cluster contour coefficients first increase and then decrease. When the number of clusters is 7, the cluster contour coefficient reaches the maximum value of 0.24. e leader factor, offensive contribution factor, shooting stability factor, and passing ability factor in the absolute core grouping are all the maximum values, which are 0.59, 0.51, 0.47, and 0.43, respectively. ese results show that the absolute core group has an important influence on the team's score. e main influence factors of absolute core are leader factor, offensive contribution factor, shooting stability factor, and passing ability factor.

Conclusion
e KMC algorithm in metaheuristic clustering is optimized and applied to the analysis of NBA scoring functional factors in this study. e results of statistical analysis of basketball technical indicators show that there are significant differences in the gain and loss of scores, and other differences are not significant. It turns out that the optimized KMC algorithm reduces the number of iterations and convergence time and improves the clustering accuracy. e leader factor, offensive contribution factor, shooting stability factor, and passing ability factor are functional factors of NBA scoring. However, there are still some shortcomings in this study. Only a preliminary analysis of the functional factors of basketball NBA scores has been carried out, and the clustering results of different players of different teams have not been analyzed and verified. erefore, it will further increase Offensive contribution factor ree-point ability factor Passing ability factor the sample size and perform cluster analysis to verify the different players of the team in future. In short, this study provides a reference basis for big data clustering and visual management.
