Nevertheless you can of course start with reducing to 30 variables maybe due to time issues. I am trying to use ant search with default evaluator fuzzy rough subset and CfsSubsetEval for attribute evaluator. Sorry, I do not have a worked example of GAs for feature selection. I am a bit new in Data Mining. I just now want if these results are satisfactory to adaopt this solution. Evaluate the attribute sets and select only the best k. Sorry, I do not have an example.

    Comparison of Feature Selection Strategies for Classification using Rapid Miner. Feature selection is observed to be an lively and vigorous research area in many fields [22] ABSTRACT: Feature selection is an important part in any of the data KEYWORDS: Feature selection, Optimized selection, Genetic algorithm, Rapid miner.
    The 14th attribute representing the class is nominal and consiists of 12 actions that can be performed by the systems.

    It seems that Weka has really helped you in your machine learning journey. Perhaps you could use a smaller sample of your data for feature selection?

    Figure 5: RapidMiner process to automatically analyze the feature weights for 8 different weighting methods.

    , with the objective of building a predictive model, through learning algorithms or data mining techniques to define features and novelty, models for each of the five geographical regions selected (all from . conjuncture changed as big companies are now willing to try cheaper, faster and more elegant. The freely available Weka software has wrapper ability.

    But another way to use wrapperbased feature selection methods cheaply is to use RapidMiner, a GNU.

    1. The population plotter is updated in these generations. Hello Jason Thank for all your great articles, the are very useful.

    2. The latter, BestFirst, is preferred if you can spare the compute time. Yes, you can implement it yourself for use in Weka.

    3. No, sorry. I want to know how weka will know in which column I have placed my deciding variable?
