Uses of UnsupervisedFilter in weka.filters.unsupervised.attribute
 

Classes in weka.filters.unsupervised.attribute that implement UnsupervisedFilter
 class 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.
 class Add
          An instance filter that adds a new attribute to the dataset.
 class AddCluster
          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 AddExpression
          An instance filter that creates a new attribute by applying a mathematical expression to existing attributes.
 class AddID
          An instance filter that adds an ID attribute to the dataset.
 class AddNoise
          An instance filter that changes a percentage of a given attributes values.
 class AddValues
          Adds the labels from the given list to an attribute if they are missing.
 class Center
          Centers all numeric attributes in the given dataset to have zero mean (apart from the class attribute, if set).
 class ChangeDateFormat
          Changes the date format used by a date attribute.
 class 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).
 class Copy
          An instance filter that copies a range of attributes in the dataset.
 class Discretize
          An instance filter that discretizes a range of numeric attributes in the dataset into nominal attributes.
 class 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.
 class KernelFilter
          Converts the given set of predictor variables into a kernel matrix.
 class MakeIndicator
          A filter that creates a new dataset with a boolean attribute replacing a nominal attribute.
 class MathExpression
          Modify numeric attributes according to a given expression

Valid options are:

 class MergeManyValues
          Merges many values of a nominal attribute into one value.
 class MergeTwoValues
          Merges two values of a nominal attribute into one value.
 class NominalToBinary
          Converts all nominal attributes into binary numeric attributes.
 class NominalToString
          Converts a nominal attribute (i.e.
 class Normalize
          Normalizes all numeric values in the given dataset (apart from the class attribute, if set).
 class 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.
 class NumericTransform
          Transforms numeric attributes using a given transformation method.
 class Obfuscate
          A simple instance filter that renames the relation, all attribute names and all nominal (and string) attribute values.
 class PKIDiscretize
          Discretizes numeric attributes using equal frequency binning, where the number of bins is equal to the square root of the number of non-missing values.

Ying Yang, Geoffrey I.
 class 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.
 class RandomProjection
          Reduces the dimensionality of the data by projecting it onto a lower dimensional subspace using a random matrix with columns of unit length (i.e.
 class Remove
          An filter that removes a range of attributes from the dataset.
 class RemoveType
          Removes attributes of a given type.
 class RemoveUseless
          This filter removes attributes that do not vary at all or that vary too much.
 class Reorder
          A filter that generates output with a new order of the attributes.
 class ReplaceMissingValues
          Replaces all missing values for nominal and numeric attributes in a dataset with the modes and means from the training data.
 class Standardize
          Standardizes all numeric attributes in the given dataset to have zero mean and unit variance (apart from the class attribute, if set).
 class StringToNominal
          Converts a string attribute (i.e.
 class StringToWordVector
          Converts String attributes into a set of attributes representing word occurrence (depending on the tokenizer) information from the text contained in the strings.
 class SwapValues
          Swaps two values of a nominal attribute.
 class 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.
 class 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.
 

Uses of UnsupervisedFilter in weka.filters.unsupervised.instance
 

Classes in weka.filters.unsupervised.instance that implement UnsupervisedFilter
 class NonSparseToSparse
          An instance filter that converts all incoming instances into sparse format.
 class Randomize
          Randomly shuffles the order of instances passed through it.
 class RemoveFolds
          This filter takes a dataset and outputs a specified fold for cross validation.
 class RemoveFrequentValues
          Determines which values (frequent or infrequent ones) of an (nominal) attribute are retained and filters the instances accordingly.
 class RemoveMisclassified
          A filter that removes instances which are incorrectly classified.
 class RemovePercentage
          A filter that removes a given percentage of a dataset.
 class RemoveRange
          A filter that removes a given range of instances of a dataset.
 class RemoveWithValues
          Filters instances according to the value of an attribute.
 class Resample
          Produces a random subsample of a dataset using either sampling with replacement or without replacement.
 class ReservoirSample
          Produces a random subsample of a dataset using the reservoir sampling Algorithm "R" by Vitter.
