Class InMemory

java.lang.Object

weka.classifiers.evaluation.output.prediction.AbstractOutput

weka.classifiers.evaluation.output.prediction.InMemory

All Implemented Interfaces:

Serializable, OptionHandler

public class InMemory
extends AbstractOutput

* Stores the predictions in memory for programmatic retrieval.
* Stores the instance, a prediction object and a map of attribute names with their associated values if an attribute was defined in a container per prediction.
* The list of predictions can get retrieved using the getPredictions() method.
* File output is disabled and buffer doesn't need to be supplied. *

* Valid options are:

* *

 -p <range>
 *  The range of attributes to print in addition to the classification.
 *  (default: none)

* *

 -distribution
 *  Whether to turn on the output of the class distribution.
 *  Only for nominal class attributes.
 *  (default: off)

* *

 -decimals <num>
 *  The number of digits after the decimal point.
 *  (default: 3)

* *

 -file <path>
 *  The file to store the output in, instead of outputting it on stdout.
 *  Gets ignored if the supplied path is a directory.
