Tackling Ant Colony Optimization Meta-Heuristic as Search Method in Feature Subset Selection Based on Correlation or Consistency Measures
Description
This paper introduces the use of an ant colony optimization
(ACO) algorithm, called Ant System, as a search method in two wellknown
feature subset selection methods based on correlation or consistency
measures such as CFS (Correlation-based Feature Selection) and
CNS (Consistency-based Feature Selection). ACO guides the search using
a heuristic evaluator. Empirical results on twelve real-world classification
problems are reported. Statistical tests have revealed that InfoGain is a
very suitable heuristic for CFS or CNS feature subset selection methods
with ACO acting as search method. The use of InfoGain is shown to be
the significantly better heuristic over a range of classifiers. The results
achieved by means of ACO-based feature subset selection with the suitable
heuristic evaluator are better for most of the problems comparing
with those obtained with CFS or CNS combined with Best First search.
