Concentrations for each substance were randomly sampled from a uniform distribution within ranges relevant for bacterial fermentations. This approach ensures that all possible combinations of concentrations have an equal chance of appearing in the dataset, effectively preventing correlations among the substances. Lower concentrations were deliberately oversampled to enhance predictive accuracy for models trained on data within that range.
