Uses of SimpleFilter in weka.filters.unsupervised.attribute
Subclasses of SimpleFilter in weka.filters.unsupervised.attribute Modifier and Type Class Description classCartesianProductA filter for performing the Cartesian product of a set of nominal attributes.classClassAssignerFilter that can set and unset the class index.classDateToNumericA filter for turning date attributes into numeric ones.classFixedDictionaryStringToWordVectorConverts String attributes into a set of attributes representing word occurrence (depending on the tokenizer) information from the text contained in the strings.classInterquartileRangeA filter for detecting outliers and extreme values based on interquartile ranges.classKernelFilterConverts the given set of data into a kernel matrix.classMergeInfrequentNominalValuesMerges all values of the specified nominal attributes that are insufficiently frequent.classNumericCleanerA 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.classNumericToDateA filter for turning numeric attributes into date attributes.classNumericToNominalA filter for turning numeric attributes into nominal ones.classPartitionedMultiFilterA filter that applies filters on subsets of attributes and assembles the output into a new dataset.classRandomSubsetChooses a random subset of non-class attributes, either an absolute number or a percentage.classRemoveByNameRemoves attributes based on a regular expression matched against their names.classRenameAttributeThis filter is used for renaming attributes.
Regular expressions can be used in the matching and replacing.

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)
