摘　　要：传统的挖掘方法在进行羽毛球后场正手高远球速度变化规律挖掘时没有针对挖掘节点进行并行化改进,因此支持度阈值高。针对这一问题,提出羽毛球后场正手高远球速度变化规律挖掘方法。从局部特征、关联规则、孤立点三个分析角度进行高远球速度变化规律挖掘种类判定,得出种类判定表达式;针对3种情况下的挖掘节点进行并行化改进,得出该信息在高远球速度变化规律挖掘种类中所处的真实位置。实验结果表明,设计的挖掘方法在相同的执行时间中支持度阈值明显低于实验对照组,验证了设计方法在羽毛球后场正手高远球速度变化规律挖掘中的高效性。Due to the traditional method,there is no parallel improvement for nodes in the exploration of the velocity variation law of forehand high clear in badminton backcourt,so the support threshold is high.In order to solve this problem,a method for exploring the velocity variation law of forehand high clear in badminton backcourt is proposed.Based on the analysis of local characteristics,association rules and outliers,the classification determination of the law is made,and the expression of the classification determination is obtained.The real position of the information in the variety of high clear velocity is obtained by improving the parallel of the exploration nodes in three cases.The experimental results show that the support threshold of the design method is significantly lower than that of the experimental control group in the same execution time,which verifies the efficiency of the design method in the exploration of the velocity variation law of forehand high clear in badminton backcourt.
