SEE: setBoostType

Returns:

automatically generated

setBoostType

public void setBoostType(int val)

getBoostType SEE: getBoostType

Parameters:

val - automatically generated

getWeakCount

public int getWeakCount()

SEE: setWeakCount

Returns:

automatically generated

setWeakCount

public void setWeakCount(int val)

getWeakCount SEE: getWeakCount

create

public static Boost create()

Creates the empty model. Use StatModel::train to train the model, Algorithm::load<Boost>(filename) to load the pre-trained model.

Returns:

automatically generated

load

public static Boost load(String filepath,
 String nodeName)

Loads and creates a serialized Boost from a file Use Boost::save to serialize and store an RTree to disk. Load the Boost from this file again, by calling this function with the path to the file. Optionally specify the node for the file containing the classifier

Parameters:

filepath - path to serialized Boost

nodeName - name of node containing the classifier

Returns:

automatically generated

load

public static Boost load(String filepath)

Loads and creates a serialized Boost from a file Use Boost::save to serialize and store an RTree to disk. Load the Boost from this file again, by calling this function with the path to the file. Optionally specify the node for the file containing the classifier

Parameters:

filepath - path to serialized Boost

Returns:

automatically generated
