Specifically, the proposed model can select the most significant synthetic factors for the generation of (6,12)-ring-containing structure. First, a random subspace method is employed to prerank the synthetic factors based on the predictive performance of a support vector machine. Then, the Fisher score is presented to rank the synthetic factors for getting a fusion weight. Finally, a sequential forward search method is utilized to select the most significant synthetic factors in view of the highest predictive performance. Specially, the principal-component-analysis method is adopted as guidance for estimating the random subspace dimension. The results are judged on the numerical prediction of (6,12)-ring-containing AlPO structures. Simultaneously, we compare our method with several classical feature selection methods. The experimental results show that the proposed model exhibits higher predictive accuracy with less synthetic factors. The results also provide an important guidance for the rational design and synthesis of microporous materials.
