Method Configuration filesIn KEEL, every method uses a configuration file to extract the values of the parameters which will be employed during its execution. Although it is generated automatically by the KEEL GUI (by using the information contained in the corresponding method description file, and the values of the parameters specified by the user), it is important to fully describe its structure because any KEEL method must be able to completely read it, in order to get the values of its parameters specified in each execution. Each configuration file has the following structure:
Input filesThe files in the inputData list must be separated by one space, being each one surrounded by quotation marks (""). If a validation file is employed by the method, the files will appear in the following order: input data= <training file> <validation file> <test file> If not, the order employed will be: input data= <training file> <test file> The validation file is a copy of the original train data employed at the start of the experiment. It is often employed for comparison tasks between the initial data and training data when it has been preprocessed. Finally, if the method perform tasks of unsupervised learning, no validation and test files are employed. Thus, the files employed will be: input data= <training file> Output files
Additional output files can be specified in this list. Although the will be not managed by other KEEL methods, it is possible to employ them to extract useful information from the execution of the method (representation of models extracted, additional outputs, performance measures...). They must be marked with the extension .txt. ParametersThe rest of the configuration file is used to describe the values of the parameters. In each line appears one parameter, followed by a "=" sign and its assigned value. If the method needs a seed to initialize a random number generator, it must be the first parameter described, employing seed as name of the parameter. Example of useThis is a valid example of a Method Configuration file (data files lists are not fully shown): |
