چکیده

This paper discusses a genetic implementation of the growing hyperspheres classifier (GHS) for highdimensional data classification. The main idea of the GHS classifier consists in data separation by n-dimensional hyperspheres properly spread over the training data. First, the idea of training data representation is described. Then a brief description of a previous first representation by neural networks is reminded. The main part of this paper is focused on a precise description of the classifier implementation by genetic algorithms. Features of the new approach are discussed and compared. Finally, a task classifying data from a gamma telescope is presented to show the capabilities of the classifier.

Proposing a Novel Cost Sensitive Imbalanced Classification Method based on Hybrid of New Fuzzy Cost Assigning Approaches, Fuzzy Clustering and Evolutionary Algorithms

In this paper, a new hybrid methodology is introduced to design a cost-sensitive fuzzy rule-based classification system. A novel cost metric is proposed based on the combination of three different concepts: Entropy, Gini index and DKM criterion. In order to calculate the effective cost of patterns, a hybrid of fuzzy c-means clustering and particle swarm optimization algorithm is utilized. This ...
