doIt

public SharedTreeModelBuilder.Score doIt(Model model,
                                Frame fr,
                                Job.ValidatedJob.Response2CMAdaptor vadaptor,
                                boolean oob,
                                boolean build_tree_one_node)

Compute CM and MSE on either the training or testing dataset. It expect already adapted validation dataset which is adapted to a model and contains a response which is adapted to confusion matrix domain. Uff :)

Parameters:

model - a model which is used to perform computation

fr - a model training frame

vadaptor - an adaptor which helps to adapt model/validation response to confusion matrix domain.

oob - perform out-of-bag validation on training frame

build_tree_one_node -

Returns:

this score object

map

public void map(Chunk[] chks)

Description copied from class: MRTask2

Override with your map implementation. This overload is given an array of local input Chunks, for Frames with arbitrary column numbers. All map variants are called, but only one is expected to be overridden.

Overrides:

map in class MRTask2<SharedTreeModelBuilder.Score>

reduce

public void reduce(SharedTreeModelBuilder.Score t)

Description copied from class: MRTask2

Override to combine results from 'mrt' into 'this' MRTask2. Both 'this' and 'mrt' are guaranteed to either have map() run on them, or be the results of a prior reduce(). Reduce is optional if, e.g., the result is some output vector.

Overrides:

reduce in class MRTask2<SharedTreeModelBuilder.Score>

report

public SharedTreeModelBuilder.Score report(Log.Tag.Sys tag,
                                  int ntree,
                                  DTree[] trees)
