First four layers of a decision tree for zeolite synthesis that Muraoka et al. extracted from a GBDT model fitted on literature data. The percentages give the fractions of the dominant phases for the complete tree with 12 layers. According to this tree, the most important factor for predicting the synthesis result is the Na/(Si + Al) ratio. Figure reprinted from Muraoka et al.⁵³⁰
