abstract = "Genetic programmingnext term (GP) is used to evolve
secondary classifiers for disambiguating between pairs
of handwritten digit images. The inherent property of
feature selection accorded by GP is exploited to make
sharper decision between conflicting classes.
Classification can be done in several steps with an
available feature set and a mixture of strategies. A
two-step classification strategy is presented in this
paper. After the first step of the classification using
the full feature set, the high confidence recognition
result will lead to an end of the recognition process.
Otherwise a secondary classifier designed using a
sub-set of the original feature set and the information
available from the earlier classification step will
help classify the input further. The feature selection
mechanism employed by GP selects important features
that provide maximum separability between classes under
consideration. In this way, a sharper decision on fewer
classes is obtained at the secondary classification
stage. The full feature set is still available in both
stages of classification to retain complete
information. An intuitive motivation and detailed
analysis using confusion matrices between digit classes
is presented to describe how this strategy leads to
improved recognition performance. In comparison with
the existing methods, our method is aimed for
increasing recognition accuracy and reliability.
Results are reported for the BHA test-set and the NIST
test-set of handwritten digits.",
