Chiraz Jlassi, Ameni Filali, Najet Arous . Dimensionality Reduction with Ensemble Learning using Growing Hierarchical Adaptive Self-Organizing Map. International Journal of Computer Applications. 187, 82 ( Feb 2026), 17-23. DOI=10.5120/ijca2026926428
Feature selection is a technique designed to reduce the complexity of learning models by selecting the most relevant features, thereby enhancing the interpretability of the models while maintaining strong generalization performance. This study addresses the challenge of choosing a subset of the most important features for each cluster within a dataset. The proposed method extends the Random Forests approach by incorporating growing hierarchical adaptive self-organizing maps (GH_AdSOM) variant for unlabelled data. It assesses the out-of-bag feature importance across multiple partitions, each generated through various bootstrap samples and a random subset of features. The GH_AdSOM represents a neural network architecture that synergizes the benefits of two key enhancements to the self-organizing map: dynamic growth and hierarchical structure. This approach allows for adaptability in map size as well as a layered organization, resulting in a powerful and flexible neural network model.
