All Implemented Interfaces:

DatasetOperation, ObjectMap, com.esotericsoftware.kryo.KryoSerializable

public class BinarizeOperation
extends java.lang.Object
implements DatasetOperation

BinarizeOperation - returns a new Dataset with binarized values: values less than the threshold are set to 0, values greater than the threshold are set to 1.

Constructor Detail

BinarizeOperation

public BinarizeOperation(double threshold)

Creates a new BinarizeOperation with the specified threshold.

Parameters:

threshold - binarization threshold.

BinarizeOperation

public BinarizeOperation()

Creates a new BinarizeOperation with a threshold of 0.

Method Detail

run

public Dataset run(Dataset input)

Binarizes a Dataset - elements less than the threshold are set to 0, elements greater than the threshold are set to 1.

Specified by:

run in interface DatasetOperation

Parameters:

input - input dataset

Returns:

new binarized Dataset or null if input is null

getSerializationVersion

public long getSerializationVersion()

Description copied from interface: ObjectMap

Returns the current version of the serialization format. Increments when the serialization format changes, i.e. backwards compatibility is broken.

Specified by:

getSerializationVersion in interface ObjectMap

Returns:

serialization version

getVersion

public int getVersion()

Description copied from interface: ObjectMap

Returns the current class version. Class version increments when the class changes but doesn't necessarily break compatibility with serialization.

Specified by:

getVersion in interface ObjectMap

Returns:

class version

getObjectMap

public java.util.Map<java.lang.String,java.lang.Object> getObjectMap()

Description copied from interface: ObjectMap

Creates a map of the important fields for the instance, suitable for serialization.

Specified by:

getObjectMap in interface ObjectMap

Returns:

"object map" of the instance

initCurrentVersion

public void initCurrentVersion(java.util.Map<java.lang.String,java.lang.Object> objectMap)

Description copied from interface: ObjectMap

Initializes an instance with a current-version object graph.

Specified by:

initCurrentVersion in interface ObjectMap

Parameters:

objectMap - object graph for initialization

getThreshold

public double getThreshold()

Threshold for binarization

setThreshold

public void setThreshold(double threshold)

Threshold for binarization
