NSPG-Miner: Mining Repetitive Negative Sequential Patterns
Yan Li, Zhulin Wang, Jing Liu +4
Sequential pattern mining (SPM) with gap constraints (or repetitive SPM or tandem repeat discovery in bioinformatics) can find frequent repetitive subsequences satisfying gap const…
Order-preserving pattern mining with forgetting mechanism
Yan Li, Chenyu Ma, Rong Gao +4
Order-preserving pattern (OPP) mining is a type of sequential pattern mining method in which a group of ranks of time series is used to represent an OPP. This approach can discover…
Co-occurrence order-preserving pattern mining
Youxi Wu, Zhen Wang, Yan Li +4
Recently, order-preserving pattern (OPP) mining has been proposed to discover some patterns, which can be seen as trend changes in time series. Although existing OPP mining algorit…
Repetitive nonoverlapping sequential pattern mining
Meng Geng, Youxi Wu, Yan Li +4
Sequential pattern mining (SPM) is an important branch of knowledge discovery that aims to mine frequent sub-sequences (patterns) in a sequential database. Various SPM methods have…
