This package for Weka >= 3.7.10
...
provides
...
several
...
jobs
...
for
...
executing
...
learning
...
tasks
...
inside
...
of
...
Hadoop.
...
These
...
include:
...
- Determining
...
- ARFF
...
- meta
...
- data
...
- and
...
- summary
...
- statisitics
...
- Computing
...
- a
...
- correlation
...
- or
...
- covariance
...
- matrix
...
- Training
...
- a
...
- Weka
...
- classifier
...
- or
...
- regressor
...
- Generating
...
- randomly
...
- shuffled
...
- (and
...
- stratified)
...
- input
...
- data
...
- chunks
...
- Evaluating
...
- a
...
- Weka
...
- classifier
...
- or
...
- regressor
...
- via
...
- cross-validation
...
- or
...
- a
...
- hold-out
...
- set
...
- Scoring
...
- using
...
- a
...
- training
...
- classifier
...
- or

interface
...
is
...
available
...
along
...
with
...
GUI
...
Knowledge
...
Flow
...
components
...
for
...
job
...
orchestration.
...
Predictive
...
models
...
learned
...
in
...
Hadoop
...
are
...
fully
...
compatible
...
with
...
Pentaho
...
Data
...
Integration's
