It is a good idea to evaluate a number of different “views” of your machine learning dataset. A view of your dataset is nothing more than a subset of features selected by a given feature selection technique. It is a copy of your dataset that you can easily make in Weka. For example,...
where CV is used to assess both the feature selection process (using genetic algorithms) and the final model selection using the features previously selected. In summary, the procedure followed in the above post is:
Feature selection refers to the process of applying statistical tests to inputs, given a specified output. The goal is to determine which columns are more predictive of the output. TheFilter Based Feature Selection componentin the designer provides multiple feature selection algorithms to choose from...
The Forward feature selection technique works in a way wherein at first a single feature is selected from the dataset and later all the features are added to the feature selection instance and later this instance object can be used to evaluate the model parameters. The mlxtend module was used ...
