This is just a short blog post to let you know that a new version of the SPMF library has been released, called version 2.52.
This new version contains two new algorithms for high utility itemset mining and one for high utility quantitative itemset mining.
- The TKU-CE algorithm for heuristically mining the top-k high-utility itemsets with cross-entropy (thanks to Wei Song, Lu Liu, Chuanlong Zheng et al., for the original code)
- The TKU-CE+ algorithm for heuristically mining the top-k high-utility itemsets with cross-entropy with optimizations (thanks to Wei Song, Lu Liu, Chuanlong Zheng et al., for the original code)
- The TKQ algorithm for mining the top-k quantitative high utility itemsets (thanks to Nouioua, M. et al., for the original code)
Besides, since December, four more algorithms have been released (in SPMF 2.50 and 2.51):
- The SFU-CE algorithm for mining skyline frequent high utility itemsets using the cross-entropy method (thanks to Wei Song, Chuanlong Zheng et al., for the original code)
- The POERMH algorithm for mining partially ordered episode rules in a sequence of events, using the head support (thanks to Yangming Chen et al. for the original code)
- The SFUI_UF algorithm for mining skyline utility itemsets using utility filtering (thanks to Wei Song, Chuanlong Zheng et al., for the original code)
- The HAUIM-GMU algorithm for mining high average utility itemsets (thanks to Wei Song, Lu Liu, et al. for the original code)
Need your contributions!
For the SPMF project, we are always looking for new contributors. If you are interested to participate (e.g. contributing code of new algorithms, bug fixes, etc.), you can contact with me at philfv AT qq.com.
