A propositionalization filter inspired by the RELAGGS algorithm.
It processes all relational attributes that fall into the user defined range (all others are skipped, i.e., not added to the output). Currently, the filter only processes one level of nesting.
The class attribute is not touched.

For more information see:

M.-A. Krogel, S. Wrobel: Facets of Aggregation Approaches to Propositionalization. In: Work-in-Progress Track at the Thirteenth International Conference on Inductive Logic Programming (ILP), 2003.


The table below describes the options available for RELAGGS.

Option Description
debug Turns on output of debugging information.
invertSelection Set attribute selection mode. If false, only selected attributes in the range will be worked on; if true, only non-selected attributes will be processed.
maxCardinality The maximum number of values a nominal attribute can have before it's skipped.


The table below describes the capabilites of RELAGGS.

Capability Supported
Class Numeric class, Date class, Binary class, Nominal class, No class, Missing class values
Attributes Empty nominal attributes, Relational attributes, Date attributes, Nominal attributes, Numeric attributes, Binary attributes, Missing values, Unary attributes
Min # of instances 0
