Class CvBoostParams

java.lang.Object

org.opencv.ml.CvDTreeParams

org.opencv.ml.CvBoostParams

public class CvBoostParams
extends CvDTreeParams

Boosting training parameters.

There is one structure member that you can set directly:

Splitting criteria used to choose optimal splits during a weak tree construction. Possible values are:

• CvBoost.DEFAULT Use the default for the particular boosting method, see below.

// C++ code:

• CvBoost.GINI Use Gini index. This is default option for Real AdaBoost; may be also used for Discrete AdaBoost.
• CvBoost.MISCLASS Use misclassification rate. This is default option for Discrete AdaBoost; may be also used for Real AdaBoost.
• CvBoost.SQERR Use least squares criteria. This is default and the only option for LogitBoost and Gentle AdaBoost.

The structure is derived from "CvDTreeParams" but not all of the decision tree parameters are supported. In particular, cross-validation is not supported.

All parameters are public. You can initialize them by a constructor and then override some of them directly if you want.
