Itemset Utility Calculator

This webpage provides a tool to calculate the utility of an itemset in the context of high utility itemset mining.

The calculations are displayed step-by-step.

This tool is not designed to be efficient but rather to be used as a tool for experimenting with the concept of utility for students. For efficient implementations of high utility itemset mining algorithms, please see the SPMF software.

To use this webpage, you need to enter a transaction database with quantities in a text area and the unit price of each item in another text area. Then you need to enter an itemset in a text field. Then you need to click a button "Calculate utility". At this moment, the step by step calculation of the utility of that itemset will be displayed to you as well as the final result.

Here is an example of a transaction database with quantities:

T1: A:2 B:3 C:1
T2: A:1 B:2 C:3 D:2
T3: A:3 B:1 C:2 D:1 E:2
T4: B:2 C:4 D:3 E:1
T5: A:2 C:3 D:2 E:3

Here is an example of the unit price of each item:

A: 5
B: 10
C: 8
D: 12
E: 15

Here is an example of an itemset:

A, C, E

Please enter your own inputs below and click the button to see the calculation.
