EXPERIMENTS DESIGN

The Experiments Design part has the objective of designing the desired experiments using a graphical interface. Doubtless, this is the more innovative tool integrated in this program. The objective is to use available datasets and algorithms to generate a directory structure with all the necessary files needed to run the designed experiments in the local computer selected by the user. Now, you can forget scripts and others parameter files that made arduous the design of an experiment, and begin to use the new windows based interface.

With this program, yon only need to select the input data (datasets), the algorithms you want to use and to make the opportune connections between them. Also it is possible to concatenate methods, insert statistical tests, etc ...

One of the tasks that was more simplified is probably the configuration of the parameters; everything can be done from a simple dialog without requirement of external configuration files.

This part of KEEL has two main objectives: on the one hand, you can use the software as a test and evaluation tool during the development of an algorithm. On the other hand, it is also a good option in order to compare new developments with standard algorithms already implemented and available in KEEL 1.0.

The interface allows the user to add his own algorithms to the experiment being designed. The only requirement is to accept the input and output file format of KEEL (refer to them in KEEL webpage). Even, it is not needed to use the Java language for your own algorithms. You only have to indicate to the program the location of the executable file and it will be automatically copied in the correct directory of the structure generated by the interface. This provides a very flexible way for the user to compare his own methods with the ones in KEEL 1.0.

In the following window, user must select the type of experiment that want to design; it is necessary that he or she selects anyone, because depending on the selection differents DataSets or algoritms will be able to use.

In this figure, you can see a snapshot of the experiment main window.
