Relative High Utility Itemset Mining

Relative High Utility Itemset Mining (RHUIM) aims to find all itemsets in a transactional database that have utility and utility ratio no less than the user-specified minimum utility and minimum utility ratio constraints.

The algorithms for RHUI-Miner has been written in Java. The command to execute the program is as follows.

compile:

javac RHUIMiner.java

executiion:

java RHUIMiner datasetName outputFile minUtil minUR

specifying threshold values

The minUtil constraint is specified in count. The minUR constraint is specified in the interval (0, 1). (for example 0.5 implies 50%)

To test the repetability of our experiments, we have provided some databases in the datasets folder.

Examples of running above code
