OutputTable
[Optional] Specify a name for the output table.
TargetColumns
Specify the names of the InputTable columns for which to output polynomial combinations for features (no more than five).
IncludeBias
[Optional] Specify whether the output table is to include a bias column for the feature in which all polynomial powers are zero (that is, a column of ones). A bias column acts as an intercept term in a linear model.
Default: true
InteractionOnly
[Optional] Specify whether to output polynomial combinations only for interaction features (features that are products of at most degree distinct input features).
Default: false
Degree
[Optional] Specify the maximum degree of the input features for which to output polynomial combinations, an integer in the range [1,2,3].
Default: 2
