Class AlgoTRuleGrowth

java.lang.Object

ca.pfv.spmf.algorithms.sequential_rules.trulegrowth.AlgoTRuleGrowth

public class AlgoTRuleGrowth
extends java.lang.Object

This is the original implementation of the TRULEGROWTH algorithm for mining sequential rules with a window size constraint. The TRuleGrowth algorithm is a variation of the RuleGrowth algorithm described in this paper:

Fournier-Viger, P., Wu, C.-W., Tseng, V.S., Nkambou, R. (2012). Mining Sequential Rules Common to Several Sequences with the Window Size Constraint. Proceedings of the 25th Canadian Conf. on Artificial Intelligence (AI 2012), Springer, LNAI 7310, pp.299-304.

Method Detail

runAlgorithm

public void runAlgorithm(double minSupport,
                         double minConfidence,
                         java.lang.String input,
                         java.lang.String output,
                         int windowSize)
                  throws java.io.IOException

Run the algorithm.

Parameters:

minSupport - Minsup as a percentage (ex: 0.05 = 5 %)

minConfidence - minimum confidence (a value between 0 and 1).

input - the input file path

output - the output file path

windowSize - a window size

Throws:

java.io.IOException - exception if there is an error reading/writing files

runAlgorithm

public void runAlgorithm(java.lang.String input,
                         java.lang.String output,
                         int relativeMinSupport,
                         double minConfidence,
                         int windowSize)
                  throws java.io.IOException

Run the algorithm.

Parameters:

relativeMinSupport - the minsup parameter as a a relative value (integer)

minConfidence - minimum confidence (a value between 0 and 1).

input - the input file path

output - the output file path

windowSize - a window size

Throws:

java.io.IOException - exception if there is an error reading/writing files

printStats

public void printStats()

Print statistics about the last algorithm execution to System.out.

getTotalTime

public double getTotalTime()

Get the total runtime of the last execution.

Returns:

the time as a double.
