Uses of SimpleFilter in weka.filters
Subclasses of SimpleFilter in weka.filtersModifier and TypeClassDescriptionclassApplies several filters successively.classThis filter is a superclass for simple batch filters.classThis filter is a superclass for simple stream filters. -
Uses of SimpleFilter in weka.filters.supervised.attribute
Subclasses of SimpleFilter in weka.filters.supervised.attributeModifier and TypeClassDescriptionclassA filter for adding the classification, the class distribution and an error flag to a dataset with a classifier.classConverts the values of nominal and/or numeric attributes into class conditional probabilities.classMerges values of all nominal attributes among the specified attributes, excluding the class attribute, using the CHAID method, but without considering re-splitting of merged subsets. -
Uses of SimpleFilter in weka.filters.supervised.instance
Subclasses of SimpleFilter in weka.filters.supervised.instanceModifier and TypeClassDescriptionclassReweights the instances in the data so that each class has the same total weight. -
Uses of SimpleFilter in weka.filters.unsupervised.attribute
Subclasses of SimpleFilter in weka.filters.unsupervised.attributeModifier and TypeClassDescriptionclassA filter for performing the Cartesian product of a set of nominal attributes.classFilter that can set and unset the class index.classA filter for turning date attributes into numeric ones.classConverts String attributes into a set of attributes representing word occurrence (depending on the tokenizer) information from the text contained in the strings.classA filter for detecting outliers and extreme values based on interquartile ranges.classConverts the given set of data into a kernel matrix.classMerges all values of the specified nominal attributes that are insufficiently frequent.classA filter that 'cleanses' the numeric data from values that are too small, too big or very close to a certain value, and sets these values to a pre-defined default.classA filter for turning numeric attributes into date attributes.classA filter for turning numeric attributes into nominal ones.classA filter that applies filters on subsets of attributes and assembles the output into a new dataset.classChooses a random subset of non-class attributes, either an absolute number or a percentage.classRemoves attributes based on a regular expression matched against their names.classThis filter is used for renaming attributes.
Regular expressions can be used in the matching and replacing.
See Javadoc of java.util.regex.Pattern class for more information:
http://java.sun.com/javase/6/docs/api/java/util/regex/Pattern.htmlclassA filter that can be used to introduce missing values in a dataset.classA simple filter for sorting the labels of nominal attributes.classTransposes the data: instances become attributes and attributes become instances. -
Uses of SimpleFilter in weka.filters.unsupervised.instance
Subclasses of SimpleFilter in weka.filters.unsupervised.instanceModifier and TypeClassDescriptionclassRemoves all duplicate instances from the first batch of data it receives.classFilters instances according to a user-specified expression.
Examples:
- extracting only mammals and birds from the 'zoo' UCI dataset:
(CLASS is 'mammal') or (CLASS is 'bird')
- extracting only animals with at least 2 legs from the 'zoo' UCI dataset:
(ATT14 >= 2)
- extracting only instances with non-missing 'wage-increase-second-year'
from the 'labor' UCI dataset:
not ismissing(ATT3)
