abstract = "In this paper the authors describe the identification
of variable interaction networks based on the analysis
of medical data. The main goal is to generate
mathematical models for medical parameters using other
available parameters in this data set. For each
variable the authors identify those features that are
most relevant for modelling it; the relevance of a
variable can in this context be defined via the
frequency of its occurrence in models identified by
evolutionary machine learning methods or via the
decrease in modeling quality after removing it from the
data set. Several data based modeling approaches
implemented in HeuristicLab have been applied for
identifying estimators for selected continuous as well
as discrete medical variables and cancer diagnoses:
Genetic programming, linear regression,
k-nearest-neighbour regression, support vector machines
(optimized using evolutionary algorithms), and random
forests. In the empirical section of this paper the
authors describe interaction networks identified for a
medical data base storing data of more than 600
patients. The authors see that whatever modeling
approach is used, it is possible to identify the most
important influence factors and display those in
interaction networks which can be interpreted without
domain knowledge in machine learning or informatics in
general.",
