Field Detail

seed

public long seed

Seed for random number generator; set to a value other than -1 for reproducibility.

max_models

public int max_models

Maximum number of models to build (optional).

max_runtime_secs

public double max_runtime_secs

Maximum time to spend building models (optional).

stopping_rounds

public int stopping_rounds

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)

stopping_metric

public ScoreKeeperStoppingMetric stopping_metric

Metric to use for early stopping (AUTO: logloss for classification, deviance for regression)

stopping_tolerance

public double stopping_tolerance

Relative tolerance for metric-based stopping criterion Relative tolerance for metric-based stopping criterion (stop if relative improvement is not at least this much)
