Detailed Description

This class encapsulates the C4.5 Algorithm used to generate a decision tree (see Grail.Simulation.DecisionTree) based on the dataset provided.

Template Parameters

TDecisionType

Member Function Documentation

ConstructTree()

std::unique_ptr< DecisionNode< ISimulatedGameAction > > grail::simulation::C45Algorithm::ConstructTree	(	Dataset &	dataset,
		int	maxDepth = decisionTreeMaxDepth
	)

Constructs a new decision tree based on the provided dataset. The decision type is given by generic argument TDecisionType.

Parameters

dataset	A dataset that contains training data for the decision tree
maxDepth	Optionally, you may limit the depth of the decision tree to @maxDepth most important levels

Returns

GetUsedColumns()

const std::unordered_set< int > & grail::simulation::C45Algorithm::GetUsedColumns

(

)

const

Gets indices of columns in the dataset used for learning with the C4.5 Algorithm that were actually used when creating the decision tree.
