My project is about Data mining (in MATLAB) and want to use Apriori and FP-GRowth to extract rules (Associate Rule Mining).
I read in somewhere on the internet, FP-Growth should be faster than Apriori because FP-Growth using tree but I'm wondering Apriori is very faster than FP-Growth why?
Is that normal? Is it a bug or something in my codes? or it can be because of my 11 features, it's too much?
My Data set have 11 Items(Columns/features) and only 118 Rows(observation) like:
1 4 9 12 13 16 19 23 27 30 31
1 4 7 10 13 17 19 23 26 29 31
I found this link on mathworks.com and another user reported a same issue but the author didn't answer me and him.
This is my project (link) to downloading and testing on google drive (NO VIRUS).
This sample is really important to me, if you have any idea please let me know.
Thanks All
