abstract = "This paper presents G-REX, a versatile data mining
framework based on genetic programming. What differs
G-REX from other GP frameworks is that it doesn't
strive to be a general purpose framework. This allows
G-REX to include more functionality specific to data
mining like preprocessing, evaluation- and optimization
methods, but also a multitude of predefined
classification and regression models. Examples of
predefined models are decision trees, decision lists,
k-NN with attribute weights, hybrid kNN-rules,
fuzzy-rules and several different regression models.
The main strength is, however, the flexibility, making
it easy to modify, extend and combine all of the
predefined functionality. G-REX is, in addition,
available in a special Weka package adding useful
evolutionary functionality to the standard data mining
tool Weka.",
