Hi, Thank you very much, your answers have been most helpful to me. From your writting, I understood that is better to go with sequence rules that periodically appear inside each sequence, opposed to periodically appearing in the whole dataset. I'm writting this paper by myself and sometimes it can be confusing, so thank you also for additional instructions, they really helped me a lot.

Hi, I started with a topic of periodic sequential rule mining and adapted RuleGrowth algorithm for that purpose, but its only one method and constraint different than the original algorithm. I was wandering is it a good idea to search for periodic sequential rules in each sequence individualy, like in sequential patterns common in multiple sequences, but for seq rules. Does that idea make some se

Thank you for directions. It is very helpful.

Hi, I have a question about possible research topic based on MRCPPS paper. In the "Conclusion" section of the paper it's proposed adapting algorithm for periodic sequential rules in sequences. Does that mean an algorithm that finds rare correlated periodic sequential rules in sequences, or just periodic sequential rules. Do rare sequential rules have importance or just top k rules?

Thank you very much, This solved the problem. I previously created separate program to group transactions by 3, because in his code he used needGroup=false and I couldn't get the same result. I am trying to recreate his results, so I can write new paper based on his. Thank you very much again, I am very greateful

I need help recreating results from paper "Discovering Rare Correlated Periodic Patterns in Multiple Sequences" (MRCPPS algorithm) for FIFA dataset. I grouped 3 itemsets per transaction and set maxsup=5. For minRa, minBond and maxStd = 0 i have 6 443 patterns found, and in Table 3. of paper it's 21 639 patterns. Am I missing something in database processing or something else?
