sklearn-weka-plugin - Release v0.0.8 Latest Release

Published by fracpete 6 months ago

using scikit-learn instead of deprecated sklearn dependency for scikit-learn (https://github.com/fracpete/sklearn-weka-plugin/pull/10)

sklearn-weka-plugin - Release v0.0.7

Published by fracpete over 1 year ago

WekaEstimator (module sklweka.classifiers) now has a custom score method that distinguishes between classification and regression to return the correct score.
renamed data to X and targets to y, since some sklearn schemes use named arguments
added dummy argument sample_weight=None to fit, score and fit_predict methods
fixed: when supplying Classifier or JBObject instead of classname/options, classname/options now get determined automatically
method to_instance (module: sklweka.dataset) now performs correct missing value check
method to_nominal_labels (module: sklweka.dataset) generates nicer labels now

sklearn-weka-plugin - Release v0.0.6

Published by fracpete over 2 years ago

WekaEstimator (module sklweka.classifiers) and WekaCluster (module sklweka.clusters) now allow specifying how many labels a particular nominal attribute or class attribute has (to avoid error message like Cannot handle unary class attribute! if there is only one label present in a particular split)

sklearn-weka-plugin - Release v0.0.5

Published by fracpete over 2 years ago

the to_nominal_attributes method in the sklearn.dataset module requires now the indices parameter (incorrectly declared as optional); can parse a range string now as well
fixed the fit, set_params and __str__ methods fo the MakeNominal transformer (module sklweka.preprocessing)
WekaEstimator (module sklweka.classifiers) and WekaCluster (module sklweka.clusters) now allow specifying which attributes to turn into nominal ones, which avoids having to manually convert the data (either as list with 0-based indices or range string with 1-based indices)
set_params methods now ignore empty dictionaries

sklearn-weka-plugin - Release v0.0.4

Published by fracpete almost 3 years ago

fixed sorting of labels in to_instances method in module sklweka.dataset
redoing X when no class present in load_arff method (module sklweka.dataset)
added load_dataset method in module sklweka.dataset that uses Weka to load the data before converting it into sklearn data structures (slower, but more flexible)
