Diversity in the decisions of a classifier ensemble appears as one of the main issues to take into account for its construction and operation. However, the potential relationship between diversity and accuracy, with respect to the resampling method and/or the classifier fusion technique has not been clearly proved. The present paper analyzes the influence of different resampling methods and dynamic weighting schemes on diversity and how this can affect to the accuracy of the classifier ensemble. This is specifically studied in the framework of the Nearest Neighbor classification algorithm.
