ai.h2o.automl.AutoML

All Implemented Interfaces:

H2ORunnable, TimedH2ORunnable, java.io.Externalizable, java.io.Serializable, java.lang.Cloneable, water.Freezable<AutoML>

public final class AutoML
extends water.Lockable<AutoML>
implements TimedH2ORunnable

H2O AutoML AutoML is used for automating the machine learning workflow, which includes automatic training and tuning of many models within a user-specified time-limit. Stacked Ensembles will be automatically trained on collections of individual models to produce highly predictive ensemble models which, in most cases, will be the top performing models in the AutoML Leaderboard.
