摘要
研究了一种从GSM系统报警数据中挖掘序列报警模式的方法。根据报警数据的特点,提出了数据清洗的方法。通过使用时间约束来限制两个报警事件在时间上的差异,利用MSAP挖掘算法获取两个报警事件之间平均的时间偏差,并发现有用的序列报警模式。
Devise a solution procedure for mining sequential alarm patterns from the alarm data of a GSM system. First, by observing the features of the alarm data, develop operations for data cleaning. By utilizing time constraints to restrict the time difference between two alarm events, devise algorithm MSAP to obtain the mean and the standard deviation of two alarm events and discover the useful sequential alarm patterns.
