|---|---|
| DistributedRowMatrix |
DistributedRowMatrix is a FileSystem-backed VectorIterable in which the vectors live in a
SequenceFile
|
| 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'.

| TimesSquaredJob | |
| TimesSquaredJob.TimesMapper | |
| TimesSquaredJob.TimesSquaredMapper<T extends org.apache.hadoop.io.WritableComparable> | |
| TimesSquaredJob.VectorSummingReducer | |
| TransposeJob |
