An efficient Pareto-based feature selection algorithm for multi-label classification.

Multi-label learning algorithms have significant challenges due to high-dimensional feature space and noises in multi-label datasets. Feature selection methods are effective techniques to deal with these problems. ParetoCluster is an effective multi-label feature selection algorithm based on Pareto dominance and cluster analysis concepts which considers each label an objective function. This algorithm loses its effectiveness to differentiate features when dealing with high labeled datasets and makes most features incomparable (e.g., when most features fall into the first layer). Thus, a cluster analysis criterion in ParetoCluster will play a decisive role in determining the most relevant features. Bearing this in mind, in this paper, we have modeled the multi-label feature selection problem into a bi-objective optimization problem regarding the relevancy and redundancy degree of the features. We then handle it using Pareto dominance in this bi-objective domain. To illustrate the optimality and efficiency of the proposed method, we have compared our approach against some similar techniques. [ABSTRACT FROM AUTHOR]
