water.automl.api.schemas3.AutoMLBuildSpecV99.AutoMLBuildControlV99

All Implemented Interfaces:

java.io.Externalizable, java.io.Serializable, java.lang.Cloneable, water.Freezable

Enclosing class:

AutoMLBuildSpecV99

public static final class AutoMLBuildSpecV99.AutoMLBuildControlV99
extends water.api.Schema<AutoMLBuildSpec.AutoMLBuildControl,AutoMLBuildSpecV99.AutoMLBuildControlV99>

The specification of overall build parameters for the AutoML process. TODO: this should have all the standard early-stopping functionality like Grid does.

Field Detail

project_name

@API(help="Optional project name used to group models from multiple AutoML runs into a single Leaderboard; derived from the training data name if not specified.")
public java.lang.String project_name

stopping_criteria

@API(help="Model performance based stopping criteria for the AutoML run.",
     direction=INPUT)
public hex.schemas.HyperSpaceSearchCriteriaV99.RandomDiscreteValueSearchCriteriaV99 stopping_criteria

nfolds

@API(help="Number of folds for k-fold cross-validation (defaults to 5, must be >=2 or use 0 to disable). Disabling prevents Stacked Ensembles from being built.",
     direction=INPUT)
public int nfolds

balance_classes

@API(help="Balance training data class counts via over/under-sampling (for imbalanced data).",
     level=secondary,
     direction=INOUT)
public boolean balance_classes

class_sampling_factors

@API(help="Desired over/under-sampling ratios per class (in lexicographic order). If not specified, sampling factors will be automatically computed to obtain class balance during training. Requires balance_classes.",
     level=expert,
     direction=INOUT)
public float[] class_sampling_factors

max_after_balance_size

@API(help="Maximum relative size of the training data after balancing class counts (defaults to 5.0 and can be less than 1.0). Requires balance_classes.",

     direction=INOUT)
public float max_after_balance_size

keep_cross_validation_predictions

@API(help="Whether to keep the predictions of the cross-validation predictions. If set to false then running the same AutoML object for repeated runs will cause an exception as CV predictions are required to build additional Stacked Ensemble models in AutoML.",
     direction=INPUT)
public boolean keep_cross_validation_predictions

keep_cross_validation_models

@API(help="Whether to keep the cross-validated models. Deleting cross-validation models will save memory in the H2O cluster.",
