Field Detail

seed

@API(help="Seed for random number generator; set to a value other than -1 for reproducibility.",
     level=secondary)
public long seed

max_models

@API(help="Maximum number of models to build (optional). Always set this parameter to ensure AutoML reproducibility: all models are then trained until convergence and none is constrained by a time budget.",
     level=secondary)
public int max_models

max_runtime_secs

@API(help="This argument specifies the maximum time that the AutoML process will run for. If both max_runtime_secs and max_models are specified, then the AutoML run will stop as soon as it hits either of these limits. If neither max_runtime_secs nor max_models are specified, then max_runtime_secs defaults to 3600 seconds (1 hour).",
     level=secondary)
public double max_runtime_secs

max_runtime_secs_per_model

@API(help="Maximum time to spend on each individual model (optional). Note that models constrained by a time budget are not guaranteed reproducible.",
     level=secondary)
public double max_runtime_secs_per_model

stopping_rounds

@API(help="Early stopping based on convergence of stopping_metric. Stop if simple moving average of length k of the stopping_metric does not improve for k:=stopping_rounds scoring events (0 to disable)",
     level=secondary)
public int stopping_rounds

stopping_metric

@API(help="Metric to use for early stopping (AUTO: logloss for classification, deviance for regression)",
     valuesProvider=AutoMLBuildSpecV99.AutoMLMetricProvider.class,
     level=secondary)
public hex.ScoreKeeper.StoppingMetric stopping_metric

stopping_tolerance

@API(help="Relative tolerance for metric-based stopping criterion (stop if relative improvement is not at least this much)",
     level=secondary)
public double stopping_tolerance
