An instance filter that adds a new attribute to the dataset.class
A filter that adds a new nominal attribute representing the cluster assigned to each instance by the specified clustering algorithm.

Changes the date format used by a date attribute.class
Filter that can set and unset the class index.class
A filter that uses a density-based clusterer to generate cluster membership values; filtered instances are composed of these values plus the class attribute (if set in the input data).class
An instance filter that copies a range of attributes in the dataset.class
A filter for turning date attributes into numeric ones.class
An instance filter that discretizes a range of numeric attributes in the dataset into nominal attributes.class
A filter for detecting outliers and extreme values based on interquartile ranges.class
A filter that creates a new dataset with a Boolean attribute replacing a nominal attribute.class
Modify numeric attributes according to a given mathematical expression.class
Merges all values of the specified nominal attributes that are insufficiently frequent.class

Converts all nominal attributes into binary numeric attributes.class
Converts a nominal attribute (i.e.class
Normalizes all numeric values in the given dataset (apart from the class attribute, if set).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
Converts all numeric attributes into binary attributes (apart from the class attribute, if set): if the value of the numeric attribute is exactly zero, the value of the new attribute will be zero.class
A filter for turning numeric attributes into date attributes.class
A filter for turning numeric attributes into nominal ones.class
Transforms numeric attributes using a given transformation method.class
A simple instance filter that renames the relation, all attribute names and all nominal attribute values.class
An attribute filter that converts ordinal nominal attributes into numeric ones
Valid options are:class
A filter that applies filters on subsets of attributes and assembles the output into a new dataset.class
Discretizes numeric attributes using equal frequency binning and forces the number of bins to be equal to the square root of the number of values of the numeric attribute.

Removes attributes based on a regular expression matched against their names.class
Removes attributes of a given type.class
This filter removes attributes that do not vary at all or that vary too much.class
This filter is used for renaming attributes.
Regular expressions can be used in the matching and replacing.
