Class NormalizeSignalOperation

java.lang.Object

com.emphysic.myriad.core.data.ops.NormalizeSignalOperation

All Implemented Interfaces:

DatasetOperation, ObjectMap, com.esotericsoftware.kryo.KryoSerializable

public class NormalizeSignalOperation
extends java.lang.Object
implements DatasetOperation

NormalizeSignalOperation - normalizes an input by subtracting the minimum value in the input and dividing by the total range i.e. for an input array M the output is Oij = (Mij - min(M))/(max(M) - min(M)).

NormalizeSignalOperation

public NormalizeSignalOperation()

Method Detail

run

public Dataset run(Dataset input)

Normalizes a Dataset by subtracting its minimum and dividing by the total range (max - min).

Specified by:

run in interface DatasetOperation

Parameters:

input - Dataset on which to operate

Returns:

normalized Dataset, or null if input was 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

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
