| Abstract:This paper discusses a problem of approximate periodicity association rules with multi-granularity time to different attribute states with the single event and the same attribute in the temporal database. Firstly，it presents some symbolic definitions for constructing multi-granularity approximate periodic association rules，and then constructs the corresponding model. Finally，the paper propo ses an algorithm based on SOM network to find approximate periodic association rules with multi-granularity. The experiments results with the stock market data demonstrate the efficiency of the proposed algorithm. |
