NetNCSP: Nonoverlapping closed sequential pattern mining

Y Wu, C Zhu, Y Li, L Guo, X Wu - Knowledge-based systems, 2020 - Elsevier
Sequential pattern mining (SPM) has been applied in many fields. However, traditional SPM
neglects the pattern repetition in sequence. To solve this problem, gap constraint SPM was …

Parameter-free probabilistic API mining across GitHub

J Fowkes, C Sutton - Proceedings of the 2016 24th ACM SIGSOFT …, 2016 - dl.acm.org
Existing API mining algorithms can be difficult to use as they require expensive parameter

Y Wu, Y Tong, X Zhu, X Wu - IEEE transactions on cybernetics, 2017 - ieeexplore.ieee.org
Sequence pattern mining aims to discover frequent subsequences as patterns in a single
sequence or a sequence database. By combining gap constraints (or flexible wildcards) …

The long and the short of it: summarising event sequences with serial episodes

N Tatti, J Vreeken - Proceedings of the 18th ACM SIGKDD international …, 2012 - dl.acm.org
An ideal outcome of pattern mining is a small set of informative patterns, containing no
redundancy or noise, that identifies the key structure of the data at hand. Standard frequent …

NetNMSP: Nonoverlapping maximal sequential pattern mining

Y Li, S Zhang, L Guo, J Liu, Y Wu, X Wu - Applied Intelligence, 2022 - Springer
