Class AlgoMSApriori

java.lang.Object

ca.pfv.spmf.algorithms.frequentpatterns.MSApriori.AlgoMSApriori

public class AlgoMSApriori
extends java.lang.Object

This is an implementation of the MSApriori algorithm as described by :

Bing Liu et al. (1999). Mining Association Rules with Multiple Minimum Supports, Proceedings of KDD 1999.

This implementation was made by AZADEH SOLTANI based on the Apriori implementation by Philippe Fournier-Viger

runAlgorithm

public void runAlgorithm(java.lang.String input,
                         java.lang.String output,
                         double beta,
                         double LS)
                  throws java.io.IOException

Run the algorithm

Parameters:

input - an input file containing a transaction database

output - an output file path for writing the result

beta - the parameter Beta for generating MIS values for all items (see paper)

LS - the parameter LS for generating MIS values for all items (see paper)

Throws:

java.io.IOException - exception if error while writing the output file

printStats

public void printStats()

Print statistics about the latest execution of the algorithm to System.out.
