| Class | Description |
|---|---|
| AbstractTimeSeries |
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.
|
| Add |
An instance filter that adds a new attribute to the
dataset.
|
| AddCluster |
A filter that adds a new nominal attribute
representing the cluster assigned to each instance by the specified
clustering algorithm.

An instance filter that creates a new attribute by
applying a mathematical expression to existing attributes.

An instance filter that adds an ID attribute to the
dataset.

An instance filter that changes a percentage of a
given attribute's values.

A filter that adds new attributes with user
specified type and constant value.

A filter for performing the Cartesian product of a set of nominal attributes.
|
| Center |
Centers all numeric attributes in the given dataset to have zero mean (apart from the class attribute, if set).
|
| ChangeDateFormat |
Changes the date format used by a date attribute.
|
| ClassAssigner |
Filter that can set and unset the class index.
|
| ClusterMembership |
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).
|
| Copy |
An instance filter that copies a range of
attributes in the dataset.
|
| DateToNumeric |
A filter for turning date attributes into numeric ones.
|
| Discretize |
An instance filter that discretizes a range of
numeric attributes in the dataset into nominal attributes.
|
| FirstOrder |
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.
|
| FixedDictionaryStringToWordVector |
Converts String attributes into a set of attributes
representing word occurrence (depending on the tokenizer) information from
the text contained in the strings.
|
| InterquartileRange |
A filter for detecting outliers and extreme values
based on interquartile ranges.
|
| KernelFilter |
Converts the given set of data into
a kernel matrix.
|
| MakeIndicator |
A filter that creates a new dataset with a Boolean
attribute replacing a nominal attribute.
|
| MathExpression |
Modify numeric attributes according to a given
mathematical expression.
|
| MergeInfrequentNominalValues |
Merges all values of the specified nominal attributes that are insufficiently frequent.
|
| MergeManyValues |
Merges many values of a nominal attribute into one
value.
|
| MergeTwoValues |
Merges two values of a nominal attribute into one
value.
|
| NominalToBinary |
Converts all nominal attributes into binary numeric
attributes.
|
| NominalToString |
Converts a nominal attribute (i.e.
|
| Normalize |
Normalizes all numeric values in the given dataset
(apart from the class attribute, if set).
|
| NumericCleaner |
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.
|
| NumericToBinary |
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.
|
| NumericToDate |
A filter for turning numeric attributes into date attributes.
|
| NumericToNominal |
A filter for turning numeric attributes into
nominal ones.
|
| NumericTransform |
Transforms numeric attributes using a given
transformation method.
|
| Obfuscate |
A simple instance filter that renames the relation,
all attribute names and all nominal attribute values.
|
| OrdinalToNumeric |
An attribute filter that converts ordinal nominal attributes into numeric ones
Valid options are: |
| PartitionedMultiFilter |
A filter that applies filters on subsets of
attributes and assembles the output into a new dataset.
|
| PKIDiscretize |
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.
For more information, see: Ying Yang, Geoffrey I. |
| PotentialClassIgnorer |
This filter should be extended by other unsupervised attribute filters to
allow processing of the class attribute if that's required.
|
| PrincipalComponents |
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. |
| RandomProjection |
Reduces the dimensionality of the data by projecting it onto a lower dimensional subspace using a random matrix with columns of unit length.
|
| RandomSubset |
Chooses a random subset of non-class attributes, either an absolute number or a percentage.
|
| Remove |
An filter that removes a range of attributes from
the dataset.
|
| RemoveByName |
Removes attributes based on a regular expression
matched against their names.
|
| RemoveType |
Removes attributes of a given type.
|
| RemoveUseless |
This filter removes attributes that do not vary at
all or that vary too much.
|
| RenameAttribute |
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.html Valid options are: |
| RenameNominalValues |
Renames the values of nominal attributes.
|
| Reorder |
A filter that generates output with a new order of
the attributes.
|

Replaces all missing values for nominal and numeric
attributes in a dataset with the modes and means from the training data.
|
| ReplaceMissingWithUserConstant |
Replaces all missing values for nominal, string,
numeric and date attributes in the dataset with user-supplied constant
values.
|

A filter that can be used to introduce missing values in a dataset.
|
| SortLabels |
A simple filter for sorting the labels of nominal
attributes.
|
| SortLabels.CaseInsensitiveComparator |
Represents a case-insensitive comparator for two strings.
|
| SortLabels.CaseSensitiveComparator |
Represents a case-sensitive comparator for two strings.
|
| Standardize |
Standardizes all numeric attributes in the given dataset to have zero mean and unit variance (apart from the class attribute, if set).
|
| StringToNominal |
Converts a range of string attributes (unspecified
number of values) to nominal (set number of values).
|
| StringToWordVector |
Converts string attributes into a set of numeric attributes representing word occurrence
information from the text contained in the strings.
|
| SwapValues |
Swaps two values of a nominal attribute.
|
| TimeSeriesDelta |
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.
|
| TimeSeriesTranslate |
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.
|
| Transpose |
