DTrees

Objective-C

@interface DTrees : StatModel

Swift

class DTrees : StatModel

The class represents a single decision tree or a collection of decision trees.

The current public interface of the class allows user to train only a single decision tree, however the class is capable of storing multiple decision trees and using them for prediction (by summing responses or using a voting schemes), and the derived from DTrees classes (such as RTrees and Boost) use this capability to implement decision tree ensembles.

Methods

  • See

    -setPriors:

    Declaration

    Objective-C

    - (nonnull Mat *)getPriors;

    Swift

    func getPriors() -> Mat

  • Creates the empty model

     The static method creates empty decision tree with the specified parameters. It should be then
 trained using train method (see StatModel::train). Alternatively, you can load the model from
 file using Algorithm::load\<DTrees\>(filename).

    Declaration

    Objective-C

    + (nonnull DTrees *)create;

    Swift

    class func create() -> DTrees

  • Loads and creates a serialized DTrees from a file

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

    Declaration

    Objective-C

    + (nonnull DTrees *)load:(nonnull NSString *)filepath
                nodeName:(nonnull NSString *)nodeName;

    Swift

    class func load(filepath: String, nodeName: String) -> DTrees

    Parameters

    filepath

    path to serialized DTree
    nodeName

    name of node containing the classifier

  • Loads and creates a serialized DTrees from a file

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

    Declaration

    Objective-C

    + (nonnull DTrees *)load:(nonnull NSString *)filepath;

    Swift

    class func load(filepath: String) -> DTrees

    Parameters

    filepath

    path to serialized DTree
