Description

Multiplies features, build polynomial features x1, x1^2, x1x2, x2, x2^2… The output should be cached otherwise the transform will recompute the features each time it is needed. Use CacheTransform.

Parameters

Name Short name Default Description
columns col   Features columns (a vector)
degree d 2 Highest degree of the polynomial features
numThreads nt   Number of threads used to estimate allowed by the transform.
