Description

Class Summary

Arffer	This class exports the data from a table to an ARFF-file.
BagArffer	This class exports the data from a table to an ARFF-file that can be used for MILK (multi instance learning kit, based on Weka). If the bag is not provided the first index is taken in the target table.
DatabaseEngine	This class encapsulates some common code for Engines that access DBs.
Engine	This class provides a simple wrapper for code that needs several arguments.
Flattener	This class flattens a given relational database into one table.
Importer	This class imports the specified datafiles (Prolog or CSV) into a database. If verbose level is >=1 the parser's verbose is set to TRUE, if it is >=2 then also the inserts are printed to stdout (can be pretty much!).
Instancer	This class creates Instances directly from the previously propositionalized database and stores them under the parameter "instances".
Milk	This class starts an MILK classifier with either an ARFF-file (Parameter "type" is then "output") or previously generated Instances (Paramter "type" is then "instances").
MilkClassifier	This class trains a MILK classifier and classifies given instances.
MilkExperimenter	This class runs experiments with a given ARFF-file. It is using MILK (the Multi Instance extension of WEKA).
Propagator	Transforms a tree structure of relations between tables into a star structure with a depth of one, i.e.
Relaggs	This class is a wrapper around RELAGGS (Propositionalization of a relational data model).
ReMilker	This class combines the aggregation from MILK and RELAGGS.
Weka	This class starts a WEKA classifier with either an ARFF-file (Parameter "type" is then "output") or previously generated Instances (Paramter "type" is then "instances").
WekaClassifier	This class trains a WEKA classifier and classifies given instances.
WekaExperimenter	This class runs experiments with a given ARFF-file. It uses the WEKA Experimenter for this.
