Description
-
Uses of SimpleFilter in weka.filters
Modifier and TypeClassDescriptionclass
Applies several filters successively.class
This filter is a superclass for simple batch filters.class
This filter is a superclass for simple stream filters. -
Uses of SimpleFilter in weka.filters.supervised.attribute
Modifier and TypeClassDescriptionclass
A filter for adding the classification, the class distribution and an error flag to a dataset with a classifier.class
Converts the values of nominal and/or numeric attributes into class conditional probabilities.class
Merges 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
Modifier and TypeClassDescriptionclass
Reweights the instances in the data so that each class has the same total weight. -
Uses of SimpleFilter in weka.filters.unsupervised.attribute
Modifier and TypeClassDescriptionclass
A filter for performing the Cartesian product of a set of nominal attributes.class
Filter that can set and unset the class index.class
A filter for turning date attributes into numeric ones.class
Converts String attributes into a set of attributes representing word occurrence (depending on the tokenizer) information from the text contained in the strings.class
A filter for detecting outliers and extreme values based on interquartile ranges.class
Converts the given set of data into a kernel matrix.class
Merges all values of the specified nominal attributes that are insufficiently frequent.class
A 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.class
A filter for turning numeric attributes into date attributes.class
A filter for turning numeric attributes into nominal ones.class
A filter that applies filters on subsets of attributes and assembles the output into a new dataset.class
Chooses a random subset of non-class attributes, either an absolute number or a percentage.class
Removes attributes based on a regular expression matched against their names.class
This 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.htmlclass
A filter that can be used to introduce missing values in a dataset.class
A simple filter for sorting the labels of nominal attributes.class
Transposes the data: instances become attributes and attributes become instances. -
Uses of SimpleFilter in weka.filters.unsupervised.instance
Modifier and TypeClassDescriptionclass
Removes all duplicate instances from the first batch of data it receives.class
Filters 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)
