Field Detail

_initialPrediction

public double _initialPrediction

Initially predicted value (for zero trees)

_ntrees

public int _ntrees

Number of trees actually in the model (as opposed to requested)

_treeKeys

public water.Key<hex.tree.CompressedTree>[][] _treeKeys

Trees get big, so store each one seperately in the DKV.

_mse_train

public double[] _mse_train

Train and validation errors per-tree (scored). Zero index is the no-tree error, guessing only the class distribution. Not all trees are scored, NaN represents trees not scored.

_mse_valid

public double[] _mse_valid

_varimp

public hex.VarImp _varimp

Variable Importance, if asked for
