Zusammenfassung
This paper describes one aspect of a machine-learning
system called HELPR that blends the best aspects of
different evolutionary techniques to bootstrap-up a
complete recognition system from primitive input data.
HELPR uses a multi-faceted representation consisting of
a growing sequence of non-linear mathematical
expressions. Individual features are represented as
tree structures and manipulated using the techniques of
genetic programming. Sets of features are represented
as list structures that are manipulated using genetic
algorithms and evolutionary programming. Complete
recognition systems are formed in this version of HELPR
by attaching the evolved features to multiple
perceptron discriminators. Experiments on datasets from
the University of California at Irvine (UCI)
machine-learning repository show that HELPR's
performance meets or exceeds accuracies previously
published.
