public AbstractErrorScaler()

Method Detail

getCapabilities

public abstract weka.core.Capabilities getCapabilities()

Returns the capabilities of this object. Returns what types of classes the scaler can handle.

Specified by:

getCapabilities in interface weka.core.CapabilitiesHandler

Returns:

the capabilities of this object

Capabilities

scale

public abstract ArrayList<Integer> scale(ArrayList data)

Scales the errors.

Parameters:

data - the data containing the errors to scale

Returns:

the scaled errors

toString

public String toString()

Returns the commandline of this object.

Overrides:

toString in class AbstractOptionHandler

Returns:

the commandline

compareTo

public int compareTo(Object o)

Compares this object with the specified object for order. Returns a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object.

Only compares the commandlines of the two objects.

Parameters:

o - the object to be compared.

Returns:

a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object.

Throws:

ClassCastException - if the specified object's type prevents it from being compared to this object.

equals

public boolean equals(Object o)

Returns whether the two objects are the same.

Only compares the commandlines of the two objects.

Overrides:

equals in class Object

Parameters:

o - the object to be compared

Returns:

true if the object is the same as this one

shallowCopy

public AbstractErrorScaler shallowCopy()

Returns a shallow copy of itself, i.e., based on the commandline options.

Returns:

the shallow copy

shallowCopy

public AbstractErrorScaler shallowCopy(boolean expand)

Returns a shallow copy of itself, i.e., based on the commandline options.

Parameters:

expand - whether to expand variables to their current values

Returns:

the shallow copy

getErrorScalers

public static String[] getErrorScalers()

Returns a list with classnames of scalers.

Returns:

the scaler classnames

forName

public static AbstractErrorScaler forName(String classname,
                                          String[] options)

Instantiates the scaler with the given options.

Parameters:

classname - the classname of the scaler to instantiate

options - the options for the scaler

Returns:

the instantiated scaler or null if an error occurred

forCommandLine

public static AbstractErrorScaler forCommandLine(String cmdline)

Instantiates the scaler from the given commandline (i.e., classname and optional options).

Parameters:

cmdline - the classname (and optional options) of the scaler to instantiate

Returns:

the instantiated scaler or null if an error occurred
