Hello, I tried to run the "/ca/pfv/spmf/algorithms/frequentpatterns/estDec/MainTest_estDec_saveToFile.java" but I received this error message Exception in thread "main" java.lang.NullPointerException at ca.pfv.spmf.algorithms.frequentpatterns.estDec.MainTest_estDec_saveToFile.fileToPath(MainTest_estDec_saveToFile.java:40) at ca.pfv.spmf.algorithms.frequentpatterns.es

would you please tell me the average size of the transactions and the average size of the maximally potentially large itemsets for the two datasets (Retail and Kosarak) which are taken from FIMI repository. Regards Maya

CfPGrowth code is a converted code from Java to C. and I found a problem in time calcutaion for this algorithm. I will fix it. Thanks alot

Thanks a lot for your reply. but with big datasets sometimes I saw a value of time like this Total time ~ -150 ms I mean with a minus sign? I don't know what to do to avoid this?

Hi, I am trying to run the CFP-Growth++ algorithm with different datasets, but some times I notice the execution time shows a negative value for the time, I don't know why or what shall I do. also when I make run for the algorithm for the same input and same circumstances I notice the execution time is different, again I don't know why or what shall I do? I will be thanksfull if you answer my

HI, I got the code but to sort the MIS array in decreasing order I used this code Arrays.sort(MIS, Collections.reverseOrder()); but I got the following exception: Exception in thread "main" java.lang.Error: Unresolved compilation problem: The method sort(int[]) in the type Arrays is not applicable for the arguments (int[], Comparator<Object> at ca.pfv.spmf.algorithm

Thank you very much for your help. I will try.

I wanted to make experiment on CFP-Growth,and I have a data set,I want to generate MIS(minimum item support) for each item for the mining of multiple support threshold. if you know the way for generating these MIS's, please let me know. Thanks in advanced

Hi, I want to generate a dataset for testing the CFP-Growth++ algorithm, If you know a data set generator for this purpose please provide it to me. Thanks in advanced.
Forum: The Data Mining / Big Data Forum

Thanks alot. I'll try.
Forum: The Data Mining / Big Data Forum

I try do that but I couldn't. but now I need to print the content of the mis tree .I you know please tell me. also in C# or the algorithm to do that. thanks in advanced.
