All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, java.util.concurrent.Future<java.lang.Void>, water.Freezable

Enclosing class:

GLM

public final class GLM.GLMSingleLambdaTsk
extends water.DTask<GLM.GLMSingleLambdaTsk>

Task to compute GLM solution for a particular (single) lambda value. Can be warm-started by passing in a state of previous computation so e.g. incremental strong rules can be applied. The performs iterative reweighted least squares algorithm with elastic net penalty.
