All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, java.util.concurrent.Future<java.lang.Void>, ForkJoinPool.ManagedBlocker, Freezable<VecUtils.MeanResponsePerLevelTask>

Enclosing class:

VecUtils

public static class VecUtils.MeanResponsePerLevelTask
extends MRTask<VecUtils.MeanResponsePerLevelTask>

Compute the mean (weighted) response per categorical level Skip NA values (those are already a separate bucket in the tree building histograms, for which this is designed)

Method Detail

map

public void map(Chunk c,
                Chunk w,
                Chunk r)

Description copied from class: MRTask

Override with your map implementation. This overload is given three local input Chunks. All map variants are called, but only one is expected to be overridden.

Overrides:

map in class MRTask<VecUtils.MeanResponsePerLevelTask>

reduce

public void reduce(VecUtils.MeanResponsePerLevelTask mrt)

Description copied from class: MRTask

Override to combine results from 'mrt' into 'this' MRTask. 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 MRTask<VecUtils.MeanResponsePerLevelTask>

postGlobal

protected void postGlobal()

Overrides:

postGlobal in class MRTask<VecUtils.MeanResponsePerLevelTask>
