DRCW-OVO: Distance-based relative competence weighting combination for One-vs-One strategy in multi-class problems

作者:

Highlights:

• The non-competence is an important problem in One-vs-One strategy.

• We develop a distance-based combination strategy, based on Dynamic Classifier Weighting strategies.

• Weights are settled depending on the closeness of the test instance to each one of the classes

• The effect of the non-competent classifiers is reduced.

• The new strategy enhances the results obtained w.r.t. the state-of-the-art aggregations.
