Constructor Detail

Score

public Score(SharedTree bldr,
     boolean oob)

Compute CM and MSE on the 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.

Parameters:

bldr - a tree-model builder with a (possibly partial) model built

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

map

public void map(water.fvec.Chunk[] chks)

Overrides:

map in class water.MRTask<Score>

reduce

public void reduce(Score t)

Overrides:

reduce in class water.MRTask<Score>
