class
An abstract instance filter that assumes instances form time-series data and
performs some merging of attribute values in the current instance with
attribute attribute values of some previous (or future) instance.
class
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.
Either the clustering algorithm gets built with the first batch of data or
one specifies are serialized clusterer model file to use instead.
class
An instance filter that creates a new attribute by
applying a mathematical expression to existing attributes.
class
An instance filter that adds an ID attribute to the
dataset.
class
An instance filter that changes a percentage of a
given attribute's values.
class
A filter that adds new attributes with user
specified type and constant value.
class
Adds the labels from the given list to an attribute
if they are missing.
class
Centers all numeric attributes in the given dataset to have zero mean (apart from the class attribute, if set).
class
Changes the date format used by a date attribute.
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
An instance filter that discretizes a range of
numeric attributes in the dataset into nominal attributes.
class
This instance filter takes a range of N numeric
attributes and replaces them with N-1 numeric attributes, the values of which
are the difference between consecutive attribute values from the original
instance.
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
Converts the given set of data into
a kernel matrix.
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
Merges many values of a nominal attribute into one
value.
class
Merges two values of a nominal attribute into one
value.
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
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
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
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.

Ying Yang, Geoffrey I.
class
Performs a principal components analysis and
transformation of the data.
Dimensionality reduction is accomplished by choosing enough eigenvectors to
account for some percentage of the variance in the original data -- default
0.95 (95%).
Based on code of the attribute selection scheme 'PrincipalComponents' by Mark
Hall and Gabi Schmidberger.
class
Reduces the dimensionality of the data by projecting it onto a lower dimensional subspace using a random matrix with columns of unit length.
class
An filter that removes a range of attributes from
the dataset.
class
Removes attributes of a given type.
class
This filter removes attributes that do not vary at
all or that vary too much.
class
Renames the values of nominal attributes.
class
A filter that generates output with a new order of
the attributes.
class
Replaces all missing values for nominal and numeric
attributes in a dataset with the modes and means from the training data.
class
Replaces all missing values for nominal, string,
numeric and date attributes in the dataset with user-supplied constant
values.
class
A filter that can be used to introduce missing values in a dataset.
class
Standardizes all numeric attributes in the given dataset to have zero mean and unit variance (apart from the class attribute, if set).
class
Converts a range of string attributes (unspecified
number of values) to nominal (set number of values).
class
Converts string attributes into a set of numeric attributes representing word occurrence
information from the text contained in the strings.
class
Swaps two values of a nominal attribute.
class
An instance filter that assumes instances form time-series data and replaces attribute values in the current instance with the difference between the current value and the equivalent attribute attribute value of some previous (or future) instance.
class
An instance filter that assumes instances form time-series data and replaces attribute values in the current instance with the equivalent attribute values of some previous (or future) instance.
class
Transposes the data: instances become attributes and attributes become instances.
