Method Detail

weightedMean

public double weightedMean()

map

public void map(Chunk response,
       Chunk weight,
       Chunk offset)

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<FrameUtils.WeightedMean>

reduce

public void reduce(FrameUtils.WeightedMean 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<FrameUtils.WeightedMean>
