public class GenISplineGamOneColumn
extends water.MRTask<GenISplineGamOneColumn>

Gamified one gam column at a time using I-spline. See doc in the GH issue: https://github.com/h2oai/h2o-3/issues/7261. This one is different from AddISGamColumns because it generates the penalty matrix, zTranform if applicable and perform scaling of the penalty matrix apart from performing gamification.
