Chunkai Zhang, Quanjian Dai, Zilin Du, Wensheng Gan, Jian Weng, Philip S. Yu
2021 arXiv   pre-print
In this paper, we propose a novel algorithm, fast utility-driven contiguous sequential pattern mining (FUCPM), to address the CSPM problem.  ...  Recently, contiguous sequential pattern mining (CSPM) gained interest as a research topic, due to its varied potential real-world applications, such as web log and biological sequence analysis.  ...  Previous studies on CSPM are mostly based on frequency, while only a few studies [25] , [26] , [27] have been conducted to address the problem of utility-driven contiguous sequential pattern mining  ...
