<p><b>Abstract</b>—Discretization can turn numeric attributes into discrete ones. Feature selection can eliminate some irrelevant and/or redundant attributes. Chi2 is a simple and general algorithm that uses the χ<super>2</super> statistic to discretize numeric attributes repeatedly until some inconsistencies are found in the data. It achieves feature selection via discretization. It can handle <it>mixed</it> attributes, work with <it>multiclass</it> data, and remove <it>irrelevant</it> and <it>redundant</it> attributes.</p>
Discretization, feature selection, pattern classification.
