Statistical computation of feature weighting schemes through data estimation for nearest neighbor classifiers

作者:

Highlights:

• Redundant features may deteriorate the performance of the Nearest Neighbor rule.

• This paper proposes a new feature weighting classifier to overcome this problem.

• Imputation methods are used to estimate a distribution of values for each feature.

• A statistical test sets weights based on differences of the feature distributions.

• Our proposal outperforms the rest of the classifiers considered in the comparisons.
