In this tutorial, we show how to build association rule on a large dataset using an external program.
Our implementation of A PRIORI is fast but needs a lot of memory that limits its performances when we treat a big dataset or generate numerous rules. I have discovered the Christian BORGELT’s work, he proposes a very powerful association rule generator, which can handle huge dataset and is very fast.
To execute its implementation, we integrated a new approach in TANAGRA: the launching and the control of an external program. At the time of the execution, we create a temporary file, which we transmit to his program (APRIORI.EXE). Then the rules are automatically downloaded and displayed.
