Deprecated.

Constructor for a nominal split in binary format. 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 - all nominal split values in the order of their integer mapping

splitMappingsLeft - the integer mapping values for the nominal values that fall into the left partition

splitMappingsRight - the integer mapping values for the nominal values that fall into the right partition

children - the children split according to the split values

Method Detail

getClassCounts

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

Deprecated.

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

Overrides:

getClassCounts in class DecisionTreeNodeSplitNominal

Parameters:

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

row - input pattern

spec - the corresponding table spec

Returns:

HashMap class/count

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)

Deprecated.

Add colors for a pattern given as a row of values.

Overrides:

addCoveredColor in class DecisionTreeNodeSplitNominal

Parameters:

Deprecated.

Overrides:

getStringSummary in class DecisionTreeNodeSplitNominal

Returns:
