Description
Technical Field
The invention relates to the technical field of sports score evaluation, in particular to a method and a system for generating a football score for a middle school examination based on a neural network.
Background
The technical field of sports score evaluation is a field which is focused on quantitative evaluation of sports performance through scientific and technological means. A core goal of this technical field is to provide objective, accurate and efficient assessment methods so that teachers, coaches and assessment staff can fair assess the physical performance of students or athletes. In educational systems, particularly in mid-level educational phases, assessment of athletic performance is an important component of student comprehensive quality assessment involving the mastery of motor skills, physical performance and motor rules. This assessment method needs to consider not only the technical details of sports such as skills and tactics, but also the educational value of sports activities and the impact on student physical and mental development.
The method for generating the football score of the middle school student is an evaluation system specially designed for football items in sports exams of the middle school student, and aims to provide a quantified scoring standard for the performance of the student on the football items. Such a method would cover a number of aspects such as ball skills, performance on a course, tactical understanding capabilities, team cooperation capabilities, etc. In particular, ball winding performance is one of the important evaluation indexes for testing the comprehensive ability of the student to control the ball skill and speed, and the proficiency of the student in controlling the ball skill is quantified by setting standardized winding routes and time limits. The purpose of the generating method is to ensure fairness, objectivity and standardization of the sports performance of the middle school test, so that all examinees are evaluated under the same standard.
While the prior art effectively supports basic assessment of athletic performance, there are significant shortcomings in real-time data processing and analysis. Existing methods face challenges in capturing and resolving critical events that occur in a game, such as ball entry or interception, and in rapidly converting these events into quantifiable scoring criteria. Furthermore, the prior art fails to provide adequate solutions in comprehensively considering athlete performance in many ways, such as comprehensive assessment under the interaction of technical skills and physical fitness. While the prior art has advanced in ensuring standardization and consistency of the assessment process, there are still shortcomings in dynamically adjusting the scoring criteria to reflect the changing performance criteria of athletic sports. In particular, the prior art fails to provide adequate methods and tools in how to adjust the scoring system to ensure that the scoring criteria are both fair and reflect the current level of athletic activity, based on recent game data and performance trends. Furthermore, while the prior art has helped in assessing the past and current performance of an athlete, there remains a deficiency in predicting the athlete's future performance potential and providing targeted development advice. In particular, the lack of the ability to analyze athlete long-term data, identify growth trends and potential, and develop more scientific training programs and game strategies for athletes and coaches, using advanced data analysis and machine learning models, has not provided effective support.

S5: based on the optimized scoring system, a gradient elevator algorithm is adopted, a model is established by utilizing historical data, future performance and growth potential of athletes are predicted, and performance prediction models are generated by cross verification of optimized model parameters;
s6: based on a performance prediction model, a neural symbol learning method is adopted, the action and strategy of football is represented through symbol logic, the relation between symbols and athlete performances is analyzed by using a deep learning model, and a symbolized skill and strategy evaluation result is generated;
S7: based on the efficiency analysis result, the updated efficiency analysis result, the corrected scoring standard, the optimized scoring system, the performance prediction model, the symbolized skills and the strategy evaluation result, an integrated learning method is adopted to construct an evaluation framework, a score generation and development scheme is provided for athletes, and a comprehensive performance evaluation result and a development plan are generated.
The efficiency analysis results comprise comprehensive scores, efficiency ranks and key performance indexes of athletes, the updated efficiency analysis results comprise adjusted athlete efficiency scores, real-time game performance updates and key event response evaluations, the corrected scoring standards comprise newly set scoring thresholds, adjusted skill weights and scoring dimensions, the optimized scoring system comprises optimized scoring indexes, newly added performance dimensions and removed redundant indexes, the performance prediction model comprises predicted growth tracks, key capacity improvement areas and potential performance bottlenecks, the symbolized skill and strategy evaluation results comprise symbolized skill mastery levels, strategy execution effects and personal improvement schemes, and the comprehensive performance evaluation results and development plans comprise personal comprehensive capacity evaluation, targeted development schemes and formulated training targets.
In step S1, the performance of the athlete is evaluated by using a data envelope analysis model (DEA) and a random front analysis model (SFA) in combination. First, the athlete's basic data and game performance data are collected, and the data format includes, but is not limited to, excel or CSV files, in which key indexes such as training time, physical quality test result, performance in the game, etc. of the athlete are recorded in detail. The data is then pre-processed, including cleaning of missing values and normalization, using the Python programming language, with the Pandas library to ensure data quality and consistency. Subsequently, DEA analysis is performed using the PyDEA library, which calculates the position of each athlete with respect to the efficiency front by setting input (e.g., training time and physical quality) and output parameters (e.g., goal accuracy and running speed), thereby obtaining a preliminary efficiency score. To further improve the accuracy of the assessment, the SFA analysis is performed using the front package in the R package with the DEA result as input, which adjusts the efficiency score by processing random fluctuations in the data to more accurately reflect the athlete's actual performance. Finally, the series of operations generate report files containing analysis results of the comprehensive efficiency of the athletes, and scientific basis is provided for subsequent scoring and development planning.
In step S2, key events in the game are captured in real time using a Complex Event Processing (CEP) algorithm, and efficiency analysis data of the athlete is updated in conjunction with the event information. This step begins by collecting real-time data during the game, including player position, ball movement trajectory, etc., through real-time data stream capture techniques such as sensors and video analysis tools. Then, event patterns and logic are defined by using the CEP software platform, such as Esper, to identify key events in the game in real time, such as goal, boost, key defender, etc. Whenever these events are identified, the system automatically combines the event information with the existing efficiency analysis data, using the Pandas library of Python for data consolidation and updating, ensuring that each athlete's data can reflect their immediate performance in the game in real time. In this way, updated efficiency analysis results are generated that include not only the athlete's base performance data, but also integrate real-time performance in the game, providing data support for more accurate assessment of the athlete's overall performance.
In step S3, based on the updated efficiency analysis result, the consistency and fairness of the scoring process are analyzed by using a hypothesis testing method, and meanwhile, the reliability of the scoring standard is determined by using confidence interval estimation. Firstly, carrying out statistical analysis by adopting SciPy libraries of Python, executing t-test and other hypothesis test functions, and comparing the mean value differences of the efficiency scores of different groups of athletes, thereby evaluating the consistency of the scoring process. Next, using the confidence interval estimation method, a 95% confidence interval for the score is calculated based on the sample mean and standard deviation of the player efficiency score, which helps evaluate the stability and reliability of the scoring criteria. Finally, according to the statistical analysis result, the scoring process is optimized by adjusting the weight and the threshold value in the scoring standard, so that the fairness and the accuracy of scoring are ensured. Through the refinement operations, a corrected scoring standard is generated, and a solid statistical basis is provided for fairly and objectively evaluating the performance of athletes.
In step S4, the scoring system is optimized by the entropy calculation method of the information theory and the information gain analysis. Firstly, based on the corrected scoring standard, performing entropy calculation on the competition index by using a feature_selection module of SciKit-Learn library of Python. The process includes quantifying the amount of information for each game indicator, such as shot accuracy, running speed, and an indicator with a high entropy value indicates that the indicator has a large uncertainty and amount of information in distinguishing player performance. Then, through information gain analysis, the variation of the information entropy before and after considering a certain index is calculated, and the index with the greatest influence on the scoring result is identified. These indicators reflect key aspects of athlete performance, and are critical to the accuracy and fairness of the scoring system. Finally, based on the results of entropy calculation and information gain analysis, adjusting a scoring system, including optimizing index weights and adjusting scoring dimensions, to generate an optimized scoring system. The process ensures that the scoring system can more accurately reflect the real performance of the athlete, and improves the objectivity and scientificity of scoring.
In step S5, a gradient hoist algorithm (Gradient Boosting Machine, GBM) is used to predict future performance and growth potential of the athlete. First, historical data is collected and consolidated as a training set of models, including training records of athletes, game achievements, and the like. The model is initialized by calling GradientBoostingRegressor classes through scikit-learn library of Python, key parameters are set such as n_ estimators to define the number of trees, learning_rate is set to learn rate, and max_depth is selected to be the maximum depth of the tree. Next, cross-validation is performed using a cross val score function to evaluate the model's performance on different subsets of data and optimize the model parameters. Finally, a performance prediction model is generated based on the optimal parameter combination. The model can predict the performance trend and potential of athletes in a period of time in the future, and provides scientific basis for developing training and development plans.
In step S6, the action and strategy of football is represented by symbol logic by using a neural symbol learning method, and the relation between the symbol and the player performance is analyzed by using a deep learning model. First, the player's actions and strategies in the game are converted into computer-understandable symbolic logic by symbolizing the representation. Then, a deep learning model is built using TensorFlow and Keras libraries, the model structure including input layers receiving symbolized data, multiple hidden layers processing the data using a ReLU activation function, and output layers employing a softmax function for multi-class prediction. Training the model by a fit method, and predicting the test set by a predict method to generate a symbolized skill and strategy evaluation result. The results provide a deep skill and strategic analysis for coaches and athletes, guiding improvement in athlete skills and tactics.
In the step S7, the efficiency analysis result, the performance prediction model and the symbolized skill evaluation result are comprehensively utilized, and a comprehensive evaluation framework is constructed through an integrated learning method. And (3) integrating the results of a plurality of prediction models by using VotingClassifier types in scikit-learn libraries to comprehensively evaluate the performance of the athlete. The accuracy of the assessment framework is optimized by adjusting the weight of each model in the integration. Finally, the generated comprehensive performance evaluation result and development plan are not only based on the historical performance of the athlete, but also consider the potential growth space and strategy adjustment potential, and provide comprehensive growth and development guidance for the athlete.

In the S101 substep, the basic data and the game performance data of the athlete are preprocessed through the Pandas library of Python, so that the quality of the analyzed basic data is ensured. Specifically, the dropna function is first used to remove any missing values in the dataset, ensuring data integrity. Next, the remaining blank values are filled with fillna functions, filling is performed according to the average value of the previous and subsequent data or specific logic, which ensures continuity and consistency of the dataset. Finally, the data is subjected to standardized processing by using STANDARDSCALER functions, all characteristic values are converted into a format with the mean value of 0 and the standard deviation of 1, so that the influence caused by different amounts of data is eliminated, and the subsequent efficiency analysis is more accurate and fair. The series of operations generates a preprocessed data set that provides clean, normalized input data for data envelope analysis and random front analysis.
In the sub-step S102, the pre-processed dataset is efficiently analyzed by a data envelope analysis model (DEA) using the PyDEA library of Python. Firstly, setting input parameters including basic data such as training time and physical quality, and setting output parameters as competition performance indexes such as shooting accuracy and running speed, and clearly analyzing input and output frames. Subsequently, a solve function is called to perform DEA analysis, and the efficiency value of each athlete is calculated. The DEA model evaluates the relative efficiency of each athlete by comparing the output performance of the athlete under the given input condition, and the generated DEA efficiency analysis result reveals the relative advantages and disadvantages of the athlete performance and provides basis for subsequent analysis and improvement.
In the S103 substep, random fluctuations in the DEA efficiency analysis result are processed by a random front edge analysis model (SFA) using the front package of R software. First, model parameters are set, including boundary types and distribution assumptions, etc., to establish the basic framework of the analytical model. Then, SFA analysis commands are executed to adjust the efficiency values of each player, taking into account the randomness of the data and the influence of external environmental factors. SFA analysis provides more accurate adjustment for the efficiency value of each athlete by finely processing DEA results, and the generated efficiency analysis results are closer to the actual performance of the athlete, thereby providing more scientific basis for evaluation and improvement.
Referring to fig. 3, based on the efficiency analysis result, a complex event processing algorithm is used to capture key events occurring in real time in a game, and update efficiency analysis data in combination with event information, reflect the instant performance of athletes, generate updated efficiency analysis results as follows,

s203: based on the event updated data set, adopting PyDEA library in Python and front package of R software again, carrying out data envelope analysis and random front analysis on the updated data, setting input parameters and output parameters of the model again, adjusting parameters and running analysis commands, comprehensively referring to instant performance in the competition, reflecting the efficiency state of each athlete, and generating an updated efficiency analysis result.
In the sub-step S201, based on the existing efficiency analysis result, real-time data stream monitoring is implemented by the Esper technology of the Java platform. Esper technology is capable of handling a large number of event data streams and identifying key events in a game, such as goals, yellow cards, etc., by defining complex event processing logic. In this process, event types and associated attributes are set as filtering conditions to ensure that only relevant event data is captured and parsed. The captured data is then parsed according to a predefined structure, converted into a key event information set. The process not only improves the efficiency of data processing, but also provides real-time and accurate data support for subsequent analysis.
In the S202 substep, the captured key event information is resolved in detail by the Pandas library of Python and integrated with the efficiency analysis data. In the process, information such as event type, time stamp, player ID and the like is extracted, and is combined with original efficiency analysis data through a merge function to form an updated data set. The process ensures timeliness and integrity of the data, so that the performance data of each athlete can timely reflect the actual performance of the athlete in the competition, and a basis is provided for subsequent efficiency analysis.
In a sub-step S203, the updated dataset is re-analyzed using the PyDEA library of Python and the front package of R software. By adjusting input and output parameters, such as training time and physical quality are used as input, shooting accuracy and running speed are used as output, and analysis commands are operated, comprehensive efficiency analysis is performed for instant performance in a game. The process aims to more accurately reflect the efficiency state of the athlete by considering the real-time change of the match, and an updated efficiency analysis result is generated. The result not only provides instant athlete performance feedback for coaches, but also provides scientific basis for athlete training and game strategy adjustment.
Referring to fig. 4, based on the updated efficiency analysis result, the consistency and fairness of the scoring process are analyzed by adopting a hypothesis testing method, the reliability of the scoring criteria is determined by using confidence interval estimation, the scoring criteria is optimized, the specific steps for generating the corrected scoring criteria are as follows,
S301: based on the updated efficiency analysis result, executing ttest _ind function through a SciPy library of Python, setting the significance level alpha to 0.05 for the efficiency score dataset of two groups of athletes through the designated parameters, and comparing the mean difference of two independent samples to generate a statistical result of hypothesis test;
S302: based on the statistical result of hypothesis test, using the norm/interval function of SciPy library, the parameters including confidence level 95% and mean and standard deviation calculated based on sample data, to provide a range estimation for athlete efficiency score, to generate confidence interval estimation result of efficiency score;
s303: and carrying out optimization operation of the scoring standard based on the statistical result of the hypothesis test and the confidence interval estimation result of the efficiency score, and generating a corrected scoring standard by adjusting the scoring parameter including modifying the weight and the threshold value in the scoring standard.
In the S301 substep, statistical analysis is performed on the updated efficiency analysis results by performing a t-test independent sample test (ttest _ind function) using SciPy libraries of Python. In this process, the efficiency score dataset of two groups of athletes was designated as input, and the significance level α was set to 0.05, to compare whether there was a significant difference in the mean between the two groups of data. The application of the method aims at checking consistency and fairness of the scoring process and ensuring scientificity and rationality of scoring standards. The generated hypothesis testing statistical result provides a quantitative evaluation basis for the scoring process, and whether deviation exists in a scoring system is revealed.
In the S302 substep, using the norm/interval function of the SciPy library, a confidence interval for the player efficiency score is calculated based on the statistical result of the hypothesis test. By assigning a confidence level of 95% and inputting the mean and standard deviation calculated based on the sample data, a range estimate of the confidence interval is provided for each athlete's efficiency score. The process is helpful for evaluating the reliability of the scoring standard, provides scientific basis for correcting the scoring standard, and ensures the accuracy and stability of the scoring result.
In the S303 substep, the scoring criteria are optimized by Python script based on the statistical result of the hypothesis test and the confidence interval estimation result of the efficiency score. Including adjusting weights and thresholds in the scoring criteria based on the analysis results to ensure consistency and fairness of the scoring process. Through this optimization operation, a corrected scoring criterion is generated. The process not only improves the scientificity and transparency of the scoring system, but also provides more reasonable and fair evaluation for the athlete, and ensures that the scoring result can truly reflect the performance and capability of the athlete.
Referring to fig. 5, based on the corrected scoring criteria, the information amount of each game index is evaluated by adopting an entropy calculation method in the information theory, the index having the greatest influence on the scoring result is selected by information gain analysis, the scoring system is adjusted accordingly, the specific steps for generating the optimized scoring system are as follows,
S401: based on the corrected scoring standard, performing entropy calculation on the competition indexes by using a feature_selection module of SciKit-Learn library through Python, evaluating the information quantity of each index, identifying the indexes playing a key role in distinguishing the player performance, and generating an entropy calculation result of the competition indexes;
S402: based on the entropy calculation result of the competition index, an information gain analysis method is adopted, the difference of the entropy before and after the calculation index is removed, and the information gain analysis result is generated by selecting the index with the greatest influence on the scoring result and identifying the most information value in the scoring system;
S403: based on the information gain analysis result, adjusting the scoring system, and updating the scoring system configuration, including optimizing the index weight and adjusting the scoring dimension, referring to the contribution of the index with the information gain to the accuracy of the scoring system, so that the scoring system fully reveals the real capability level of the athlete, and generating an optimized scoring system.
In the S401 substep, information entropy calculation is performed on the game index under the corrected scoring standard by using the feature_selection module in the SciKit-Learn library of Python. The process involves taking as input data each of the game metrics (e.g., training time, physical attributes, goal accuracy, and running speed), formatted as a structured data table, where each row represents a record of one athlete, and each column corresponds to one metric. By calculating the entropy of the information of these indices, we can evaluate the amount of information of each index in distinguishing the athlete's performance, i.e. its contribution to predicting the athlete's performance. The index of high information entropy indicates that the index has higher value in distinguishing different athlete performances. The generated entropy calculation result helps to identify key performance indexes, and provides basis for subsequent scoring system optimization.
The S402 substep adopts an information gain analysis method, and calculates the information gain of each index through a Python script. The process involves comparing the information entropy differences of the system with and without a certain index to evaluate the contribution of introducing the index to the improvement of the scoring system. The index with the greatest information gain is selected as the key index in the scoring system, as it contributes most to distinguishing athlete performance. The information gain analysis result generated by the step guides the further optimization of the scoring system, and ensures that the scoring system can reflect the actual performance of the athlete more accurately.
S403, adjusting a scoring system through the Python script, wherein the step comprises the steps of optimizing the weight of the scoring index and adjusting the scoring dimension. In operation, the weights of the indicators in the scoring system are adjusted and the scoring dimensions are reconfigured according to the indicators with high information gain. The purpose of this process is to ensure that the scoring system is able to evaluate the performance of the athlete more comprehensively and equitably, and is particularly effective in distinguishing between high and low performing athletes. The generated optimized scoring system not only improves the accuracy and fairness of scoring, but also provides more valuable feedback and development advice for coaches and athletes by more carefully reflecting each ability of the athlete.
Referring to fig. 6, based on the optimized scoring system, a gradient hoisting algorithm is adopted to build a model by using historical data, predict the future performance and growth potential of the athlete, and by cross-verifying the optimized model parameters, the specific steps for generating the performance prediction model are as follows,
S501: based on the optimized scoring system, selecting a gradient hoisting algorithm to initialize a model, calling GradientBoostingRegressor types through a scikit-learn library of Python, setting an n_ estimators parameter as 100 to define the number of trees, setting a learning_rate parameter as 0.1 to set a learning rate, and setting a max_depth parameter as 4 to select the maximum depth of the trees to generate a prediction model base structure;
S502: based on a prediction model infrastructure, adopting a cross_val_score function in scikit-learn library, setting cv parameters to 5 for 5-fold cross validation, setting scoring parameters to R2, adopting R2 as a scoring criterion, evaluating the performance of the model on multiple subsets, capturing average performance indexes under the parameter configuration of the model, and generating a cross validation performance evaluation result;
s503: based on the cross-validation performance evaluation result, the model parameters are adjusted and optimized, the GRIDSEARCHCV is utilized to conduct grid search of the parameters, various value ranges are set for the n_ estimators, learning _rate and the max_depth parameters for analysis, and the optimal model parameter combination is captured to generate the performance prediction model.
In a sub-step S501, the model is initialized by a gradient hoist algorithm, which uses class GradientBoostingRegressor in the scikit-learn library of Python. First, the data format is a structured data set containing historical performance and related characteristics of the athlete, each row representing a record of the athlete, and the columns containing metrics such as training time, physical quality, goal accuracy, and running speed. At model initialization, setting n_ estimators =100 defines the number of decision trees in the model, learning_rate=0.1 determines the contribution in each tree training process, and max_depth=4 limits the maximum depth of the tree, preventing model overfitting. The process builds a basic predictive model framework aimed at predicting a player's future performance based on its historical data.
In a substep S502, model performance is assessed by a 5-fold cross-validation method, using the cross val score function of the scikit-learn library. The function divides the dataset into 5 different subsets, trains using 4 subsets at a time and tests the model performance on the remaining one subset, repeating this process 5 times. The scoring = R2 parameter specifies the use of R2 as a scoring criterion to quantify the accuracy of the model predictive capability. The cross-validation performance evaluation result generated by the step reveals the average performance of the model on different data subsets, and provides basis for further adjustment of model parameters.
In a substep S503, optimization of model parameters is performed based on the results of the cross-validation, and a parametric grid search is performed using GRIDSEARCHCV. The process involves systematically testing different combinations of parameters within a predetermined parameter range (e.g., different values of n_ estimators, learning _rate, max_depth) to find parameter settings that optimize the model performance. This step determines the model configuration that best improves the prediction accuracy by analyzing the behavior of the model (using R2 scoring criteria) under different parameter combinations. The generated performance prediction model is based on the optimized parameters, has higher prediction accuracy and generalization capability, and can provide more accurate prediction about future performance and growth potential of athletes for coaches.

In the S602 substep, the neural network is trained using the fit method by setting the batch size (batch_size) to 32 and the number of iterations (epochs) to 100. In this process, the model minimizes the prediction error by processing the data batch by batch and updating the weights in each iteration. The choice of batch size and number of iterations balances training efficiency and model performance, ensuring that the model can learn patterns in the data sufficiently without overfitting. After training is completed, the generated deep learning model optimizes the network weight, and accuracy of model prediction skills and strategy evaluation is improved.
