针对用户行为轨迹数据挖掘PrefixSpan算法构造投影数据库过程中重复扫描而造成时空开销过大的问题,提出一种改进的序列模式挖掘算法TDM-PrefixSpan(trajectory data mining based on prefixSpan algorithm)。依据时间序列分布特征,采用...
This paper aims to propose the sequential pattern discovery method of Deoxyribonucleic Acid (DNA) sequence database in order to identify cancer disease. The DNA which is composed of amino acids of gene P53 is mutated....
