Class weka.experiment.RemoteExperiment

- public class RemoteExperiment
- extends Experiment
Holds all the necessary configuration information for a distributed
experiment. This object is able to be serialized for storage on disk.
This class is experimental at present. Has been tested using
CSVResultListener (sending results to standard out) and
DatabaseResultListener (InstantDB + RmiJdbc bridge).
Getting started:
Start InstantDB (with the RMI bridge) on some machine. If using java2
then specify -Djava.security.policy=db.policy to the
virtual machine. Where db.policy is as follows:
grant {
permission java.security.AllPermission;
};
Start RemoteEngine servers on x machines as per the instructons in the
README_Experiment_Gui file. There must be a
DatabaseUtils.props in either the HOME or current directory of each
machine, listing all necessary jdbc drivers.
The machine where a RemoteExperiment is started must also have a copy
of DatabaseUtils.props listing the URL to the machine where the
database server is running (RmiJdbc + InstantDB).
Here is an example of starting a RemoteExperiment:
java -Djava.rmi.server.codebase=file:/path to weka classes/ \
weka.experiment.RemoteExperiment -L 1 -U 10 \
-T /home/ml/datasets/UCI/iris.arff \
-D "weka.experiment.DatabaseResultListener" \
-P "weka.experiment.RandomSplitResultProducer" \
-h rosebud.cs.waikato.ac.nz -h blackbird.cs.waikato.ac.nz -r -- \
-W weka.experiment.ClassifierSplitEvaluator -- \
-W weka.classifiers.NaiveBayes
The "codebase" property tells rmi where to serve up weka classes from.
This can either be a file url (as long as a shared file system is being
used that is accessable by the remoteEngine servers), or http url (which
of course supposes that a web server is running and you have put your
weka classes somewhere that is web accessable). If using a file url the
trailing "/" is *most* important unless the weka classes are in a jar
file.
