A fast and stable granular ball generation method (GBG++) for classification is proposed in this paper.
GBG++ method improves the stability and efficiency of existing granular ball generation methods by using the attention mechanism.
The proposed GBG++ method calculates the distances from the data-driven center to undivided samples, resulting in improved effectiveness, robustness, and efficiency.
Experimental results show that the GBG++ method outperforms existing granular ball-based classifiers and classical machine learning classifiers on 24 public benchmark datasets.
