ISmDecisionTree

The ISmDecisionTree interface is used to substitute missing data in series values using a decision tree.

Inheritance Hierarchy

Comments

The method uses categorical data. In Foresight Analytics Platform categorical data must be presented as an integer array, in which numbers correspond to appropriate categories.

If ISmDecisionTree.Explained[i] = -1, this means that the i-th observation is missing: that is, it has not been clustered and should be classified as a member of one of the known classes using a decision tree.

Each of the series in the collection ISmDecisionTree.Explained must be defined with an array of non-negative integers that represent categories.
