thank you sir. one more doubt sir, You have used Candidate generation in SPAM, We could not understand the S-step process which you have used in it. could you please explain us on what basis your selected the k bit , i.e. the index and how are you assigning 0's and 1's to the transormed bitmap? Please explain the process using the figure 4 in the base paper of SPAM you provided

hi, can any one explain me why we used relative minsup for prefix-span and obsolete minsup for SPAM in frame work??

hello, my dataset is of 1.51mb. problem is ,i want to compare prefixspan and spam for same large dataset with same minsupport but prefix want 1% to 5% minsup to get more patterns whereas spam is running out of memory with that minsup... so im not able to make analysis for this 2 algorithms takin large datasets.i want any medium datasets for my analysis??

In SPAM algorithm if i increment BIT_PER_SECTION i was able to get Frequent sequences count upto 1053 for kosarat datasets(converted to text) but coming to prefix-span im getting just count 6. can i know any changes i have to do in prefixspan too for kosarat-datasets?

Its showing same result as count and memory 0, with all varying support..

Hello philiphe, i tried to execute the prefix span using the dataset which u gave i.e.BMS converted to text but its not giving the result and showing as Total time ~ 228 ms Frequent sequences count : 0 Max memory (mb) : 0.00 with minsup as 0.5 any solution?

thank you tisonet and philippe. can i get normal large and small data sets so that i can use them directly with out need to change the code in SPMF framework ?? Because i don't have so good hand-on experience in doing java code. so i await for this favor in doing my analysis part between prefix-span and SPAM.

I came across of algorithm SPADE in this mining process... post me criterion based analysis...among these algorithms.

hi everyone. In frequent pattern mining algorithms like prefix-span or SPAM or among any other algorithms which one would be efficient?? If you cant say directly, can you clarify me which one would be efficient considering criteria's like time,memory,no. of counts etc...?? Ill be glad if anyone help me in this analysis.

hello sir, i have problem in executing SPAM algorithm in SPMF FRAMEWORK. can you please tell me what integer should i give in minsup(minimum support count) for that inputfile you gave?? please clear me difference in relative minsup(%) used in prefix-span and absolete minsup(integer) used in SPAM??

hi My favorite too is prefix span but in SPMF frame work its implemented only to small file with integers and strings. can you upload a source code for some large data bases like transactional data???
