Detailed Description

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.

Member Function Documentation

◆ fromPtr()

static new DTrees OpenCVForUnity.MlModule.DTrees.__fromPtr__ ( IntPtr addr )

static

◆ create()

static DTrees OpenCVForUnity.MlModule.DTrees.create ( )

static

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).

◆ Dispose()

override void OpenCVForUnity.MlModule.DTrees.Dispose ( bool disposing )

protectedvirtual

Reimplemented from OpenCVForUnity.CoreModule.Algorithm.

Reimplemented in OpenCVForUnity.MlModule.RTrees.

◆ load() [1/2]

static DTrees OpenCVForUnity.MlModule.DTrees.load ( string filepath )

static

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

Parameters

filepath	path to serialized DTree
nodeName	name of node containing the classifier

◆ load() [2/2]

static DTrees OpenCVForUnity.MlModule.DTrees.load	(	string	filepath,

static

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

Parameters

filepath	path to serialized DTree
nodeName	name of node containing the classifier
