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. |
class |
AddExpression
Applys a mathematical expression involving attributes and numeric constants to a dataset. |
class |
AddNoise
Introduces noise data a random subsample of the dataset by changing a given attribute (attribute must be nominal) Valid options are: -C col Index of the attribute to be changed. |
class |
ClusterMembership
A filter that uses a clusterer to obtain cluster membership probabilites for each input instance and outputs them as new instances. |
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. eg: Original attribute values 0.1, 0.2, 0.3, 0.1, 0.3
New attribute values 0.1, 0.1, 0.1, -0.2, -0.2
The range of attributes used is taken in numeric order. |
class |
MakeIndicator
Creates a new dataset with a boolean attribute replacing a nominal attribute. |
class |
MergeTwoValues
Merges two values of a nominal attribute. |
class |
NominalToBinary
Converts all nominal attributes into binary numeric attributes. |
class |
Normalize
Normalizes all numeric values in the given dataset. |
class |
NumericToBinary
Converts all numeric attributes into binary attributes (apart from the class attribute): 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. |
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 (It will reduce the number of attributes in the data while preserving much of its variation like PCA, but at a much less computational cost). |
class |
Remove
An instance filter that deletes a range of attributes from the dataset. |
class |
RemoveType
A filter that removes attributes of a given type. |
class |
RemoveUseless
This filter removes attributes that do not vary at all or that vary too much. |
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. |
class |
StringToNominal
Converts a string attribute (i.e. unspecified number of values) to nominal (i.e. set number of values). |
class |
StringToWordVector
Converts String attributes into a set of attributes representing word occurrence 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 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
A filter that converts all incoming instances into sparse format. |
class |
Randomize
This filter 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 |
RemoveMisclassified
A filter that removes instances which are incorrectly classified. |
class |
RemovePercentage
This filter removes a given percentage of a dataset. |
class |
RemoveRange
This filter takes a dataset and removes a subset of it. |
class |
RemoveWithValues
Filters instances according to the value of an attribute. |
class |
Resample
Produces a random subsample of a dataset. |
class |
SparseToNonSparse
A filter that converts all incoming sparse instances into non-sparse format. |
