Abstract: Due to the increasing size of the datasets, instance selection techniques have been applied for reducing the computational resources involved in data mining and machine learning tasks. In this paper, we propose a global density-based approach for selecting instances. The algorithm selects only the densest instances in a given neighborhood and the instances in the boundaries among classes, while excludes potentially harmful instances. Our method was evaluated on 14 well-known datasets used in a classification task. The performance of the proposed algorithm was compared to the performances of 8 prototype selection algorithms in terms of accuracy and reduction rate. The experimental results show that, in general, the proposed algorithm provides a good trade-off between reduction rate and accuracy with reasonable time complexity.
