Accelerated Frequent Closed Sequential Pattern Mining for uncertain data
作者:
Highlights:
• Compared with basic PFCSM-FF, PFCSM-CF enhances the efficiency by avoiding invalid computation.
• A PFCSM-CC algorithm is implied to reduces the computational cost of frequent closed probability.
• The experiments are conducted to evaluate the performance of PFCSM-CF and PFCSM-CC.
