Constructor Detail

EclatProcess

public EclatProcess(myDataset dataset,
                    double minSupport,
                    double minConfidence)

It creates a new process for the algorithm by setting up its parameters

Parameters:

dataset - The instance of the dataset for dealing with its records

minSupport - The user-specified minimum support for the mined association rules

minConfidence - The user-specified minimum confidence for the mined association rules

Method Detail

run

public void run()

It runs the algorithm for mining association rules

generateRulesSet

public java.util.ArrayList<AssociationRule> generateRulesSet()

It constructs a rules set once the algorithm has been carried out

Returns:

An array of association rules having both minimum confidence and support

printReport

public void printReport(java.util.ArrayList<AssociationRule> rules)

It prints out on screen relevant information regarding the mined association rules

Parameters:

rules - The array of association rules from which gathering relevant information

roundDouble

public static double roundDouble(double number,
                                 int decimalPlace)

Rounds the number applying the BigDecimal rounding mode given.

Parameters:

number - number to be rounded.

decimalPlace - given rounding mode.

Returns:

the rounded number.

printRules

public java.lang.String printRules(java.util.ArrayList<AssociationRule> rules)

saveReport

public void saveReport(java.util.ArrayList<AssociationRule> rules,
                       java.io.PrintWriter w)
