The Multiclass ROC Front method for cost-sensitive classification

作者:

Highlights:

• We propose a new method for multiclass cost-sensitive classification when misclassification costs are unknown during training.

• It is based on a multi-model approach and can suit to any cost-sensitive environment in prediction.

• It makes use of ROC-based multi-objective optimization algorithms.

• The method is compared to a cost-insensitive method and a state-of-the-art cost-sensitive optimization method.

• It outperforms both methods for most of the datasets tested.
