The process of feature weight calculation. First, the Bayesian probabilities for each substructure were calculated. Then, substructures selected based on a log odds ratio threshold were weighted, while others remained binary. When calculating the weight vector, the feature values (x) of selected substructures were amplified by a user parameter n. The constructed weight vector was then multiplied with the original feature matrix
