|
DistributedRowMatrix.MatrixEntryWritable | |
MatrixColumnMeansJob |
MatrixColumnMeansJob is a job for calculating the column-wise mean of a
DistributedRowMatrix.
|
MatrixColumnMeansJob.MatrixColumnMeansMapper |
Mapper for calculation of column-wise mean.
|
MatrixColumnMeansJob.MatrixColumnMeansReducer |
The reducer adds the partial column-wise sums from each of the mappers to
compute the total column-wise sum.
|
MatrixMultiplicationJob |
This still uses the old MR api and as with all things in Mahout that are MapReduce is now part of 'mahout-mr'.
