ai.sklearn4j.preprocessing.label.MultiLabelBinarizer

public class MultiLabelBinarizer
extends TransformerMixin<List<Set<Object>>,NumpyArray<Long>>

Transform between iterable of iterables and a multilabel format. Although a list of sets or tuples is a very intuitive format for multilabel data, it is unwieldy to process. This transformer converts between this intuitive format and the supported multilabel format: a (samples x classes)

MultiLabelBinarizer

public MultiLabelBinarizer()

Instantiate a new object of MultiLabelBinarizer.

Method Detail

setClasses

public void setClasses(List<Object> value)

Sets the A copy of the `classes` parameter when provided. Otherwise it corresponds to the sorted set of classes found when fitting.

Parameters:

value - The new value for classes.

getClasses

public List<Object> getClasses()

Gets the A copy of the `classes` parameter when provided. Otherwise it corresponds to the sorted set of classes found when fitting.

setCachedDict

public void setCachedDict(Map<String,Object> value)

Sets the value of CachedDict

Parameters:

value - The new value for CachedDict.

getCachedDict

public Map<String,Object> getCachedDict()

Gets the value of CachedDict

transform

public NumpyArray<Long> transform(List<Set<Object>> array)

Takes the input array and transforms it.

Specified by:

transform in class TransformerMixin<List<Set<Object>>,NumpyArray<Long>>

Parameters:

array - The array to transform.

Returns:

The transformed array.

inverseTransform

public List<Set<Object>> inverseTransform(NumpyArray<Long> array)

Takes a transformed array and reveres the transformation.

Specified by:

inverseTransform in class TransformerMixin<List<Set<Object>>,NumpyArray<Long>>

Parameters:

array - The array to apply reveres transform.

Returns:

The inversed transform of array.
