DecisionTreeNodeSplitNominal

DecisionTreeNodeSplitNominal()

Deprecated.

Empty Constructor visible only within package.

DecisionTreeNodeSplitNominal

public DecisionTreeNodeSplitNominal(Node xmlNode,
                                    DataCellStringMapper mapper)

Deprecated.

Constructor of derived class. Read all type-specific information from XML File.

Parameters:

xmlNode - XML node info

mapper - map translating column names to DataCells and vice versa

DecisionTreeNodeSplitNominal

public DecisionTreeNodeSplitNominal(int nodeId,
                                    DataCell majorityClass,
                                    LinkedHashMap<DataCell,Double> classCounts,
                                    String splitAttribute,
                                    DataCell[] splitValues,
                                    DecisionTreeNode[] children)

Deprecated.

Constructor of base class. The necessary data is provided directly in the constructor.

Parameters:

nodeId - the id of this node

majorityClass - the majority class of the records in this node

classCounts - the class distribution of the data in this node

splitAttribute - the attribute name on which to split

splitValues - the split values used to partition the data

children - the children split according to the split values

Method Detail

getClassCounts

public LinkedHashMap<DataCell,Double> getClassCounts(DataCell cell,
                                                     DataRow row,
                                                     DataTableSpec spec)

Deprecated.

Determine class counts for a new pattern given as a row of values. Returns a HashMap listing counts for all classes.

Specified by:

getClassCounts in class DecisionTreeNodeSplit

Parameters:

cell - the call to be used for classification at this node

row - input pattern

spec - the corresponding table spec

Returns:

HashMap class/count

addCoveredPattern

public void addCoveredPattern(DataCell cell,
                              DataRow row,
                              DataTableSpec spec,
                              double weight)
                       throws Exception

Deprecated.

Add patterns given as a row of values if they fall within a specific node. Usually only Leafs will actually hold a list of RowKeys, all intermediate nodes will collect "their" information recursively.

Specified by:

addCoveredPattern in class DecisionTreeNodeSplit

Parameters:

cell - the cell to be used for classification at this node

row - input pattern

spec - the corresponding table spec

weight - the weight of this row (between 0.0 and 1.0)

Throws:

Exception - if something went wrong (unknown attribute for example)

addCoveredColor

public void addCoveredColor(DataCell cell,
                            DataRow row,
                            DataTableSpec spec,
                            double weight)
                     throws Exception

Deprecated.

Add colors for a pattern given as a row of values. This is a leaf so we will simply add the color to our list.

Specified by:

addCoveredColor in class DecisionTreeNodeSplit

Parameters:

cell - the cell to be used for the split at this level

row - input pattern

spec - the corresponding table spec

weight - the weight of the row (between 0.0 and 1.0)

Throws:

Exception - if something went wrong (unknown attriubte for example)

coveredPattern

public Set<RowKey> coveredPattern()

Deprecated.

Specified by:

coveredPattern in class DecisionTreeNodeSplit

Returns:

set of data cells which are the row keys that are covered by all nodes of this branch

getStringSummary

public String getStringSummary()

Deprecated.

Specified by:

getStringSummary in class DecisionTreeNode

Returns:

string summary of node content (split, leaf info...)

addNodeToTreeDepthFirst

public boolean addNodeToTreeDepthFirst(DecisionTreeNode node,
                                       int ix)

Deprecated.

Add a new node to the tree structure based on a depth-first indexing strategy.

Overrides:

addNodeToTreeDepthFirst in class DecisionTreeNodeSplit

Parameters:

node - node to be inserted

ix - index of this node in depth first traversal order

Returns:

true only if the node was successfully inserted

saveNodeSplitInternalsToPredParams

public void saveNodeSplitInternalsToPredParams(ModelContentWO pConf)

Deprecated.

save internal SplitNode settings to a ModelContent object.

Specified by:

saveNodeSplitInternalsToPredParams in class DecisionTreeNodeSplit

Parameters:

pConf - configuration object to save decision tree to

Deprecated.

Load internal SplitNode settings from a ModelContent object.

Specified by:

loadNodeSplitInternalsFromPredParams in class DecisionTreeNodeSplit

Parameters:

pConf - configuration object to load decision tree from.

Throws:
