This paper describes an improved version of a previously developed ANOVA and Functional Networks Feature Selection method. This wrapper feature selection method is based on a functional decomposition that grows exponentially as the number of features increases. Since exponential complexity limits the scope of application of the method, a new version is proposed that subdivides this functional decomposition and increases its complexity gradually. The improved version can be applied to a broader set of data. The performance of the improved version was tested against several real datasets. The results obtained are comparable, or better, to those obtained by other standard and innovative feature selection methods.
