Note that this is for learning an RDN. The basic version boosts a single conditional relational probability distribution.

Simple Usage:

• java -cp BoostSRL.jar edu.wisc.cs.Boosting.RDN.RunBoostedRDN [Args]
• java -jar BoostSRL.jar [Args]

Arguments [Args]:

• -l : enable training (learning).

• -i : enable testing (inference).

• -noBoost : disable Boosting (i.e., learns a single relational regression tree).

• -train <Training directory> : Path to the training directory in predicate logic format.

• -test <Testing directory> : Path to the testing directory in predicate logic format format.

• -model <Model directory> : Path to the directory with the stored models [or where they will be stored].

  Default location: "Training directory"/models

• -target <target predicates> : Comma separated list of predicates to be learned/inferred.

• -trees <Number of trees> : Number of Boosting trees.

  Default: 20. Ignored if -noBoost is set.

• -step <Step Length> : Default step length for functional gradient.

  Default: 1.

• -modelSuffix <suffix> : All the trees/models are saved with this suffix appended to the file names.

• -aucJarPath <path to auc.jar> : If this is not set, AUC values are not computed.

• -testNegPosRatio <Negative/Positive ratio> : Ratio of negatives to positive for testing.

  Default: 2. Set to -1 to disable sampling.

Sample Calls:

Try to follow along with what each of these are doing:

From the Getting Started tutorial:

• java -jar BoostSRL.jar -l -combine -train train/ -target father -trees 10

• java -jar BoostSRL.jar -i -model train/models -test test/ -target father -trees 10

From the Boston Housing Dataset (notice the different classpath):

• java -cp BoostSRL.jar edu.wisc.cs.will.Boosting.Regression.RunBoostedRegressionTrees -reg -l -train train/ -target medv -trees 20

From the CiteSeer Dataset:

• java -jar BoostSRL.jar -l -train train/ -target infield_fauthor,infield_ftitle,infield_fvenue -trees 5
