Field Detail

fields

public static java.lang.String[] fields

balance_classes

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

For imbalanced data, balance training data class counts via over/under-sampling. This can result in improved predictive accuracy.

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

Desired over/under-sampling ratios per class (lexicographic order). Only when balance_classes is enabled. If not specified, they will be automatically computed to obtain class balance during training.

max_after_balance_size

@API(help="Maximum relative size of the training data after balancing class counts (can be less than 1.0). Requires balance_classes.",
     level=expert,
     direction=INOUT)
public float max_after_balance_size

When classes are balanced, limit the resulting dataset size to the specified multiple of the original dataset size.

max_confusion_matrix_size

@API(help="[Deprecated] Maximum size (# classes) for confusion matrices to be printed in the Logs",
     level=secondary,
     direction=INOUT)
public int max_confusion_matrix_size

For classification models, the maximum size (in terms of classes) of the confusion matrix for it to be printed. This option is meant to avoid printing extremely large confusion matrices.

laplace

@API(help="Laplace smoothing parameter",
     gridable=true)
public double laplace

min_sdev

@API(help="Min. standard deviation to use for observations with not enough data",
     gridable=true)
public double min_sdev

eps_sdev

@API(help="Cutoff below which standard deviation is replaced with min_sdev",
     gridable=true)
public double eps_sdev

min_prob

@API(help="Min. probability to use for observations with not enough data",
     gridable=true)
public double min_prob

eps_prob

@API(help="Cutoff below which probability is replaced with min_prob",
     gridable=true)
public double eps_prob

compute_metrics

@API(help="Compute metrics on training data",
     gridable=true)
public boolean compute_metrics

seed

@API(help="Seed for pseudo random number generator (only used for cross-validation and fold_assignment=\"Random\" or \"AUTO\")",
     level=expert,
     direction=INOUT,
     gridable=true)
public long seed
