Table 3 The averaged ranking based on predictions. We tested the performance of the algorithm by using the essential ions. The test dataset is composed of the structures that are not used in the statistics of ion distributions. The averaged ranks and their standard deviations are summarized. The two best predicted ionic types (Ca²⁺ and Zn²⁺) and the worst case (Mg²⁺) are highlighted in boldface
