WebbAn interpretable machine learning framework for imbalanced high-dimensional big data of clinical microbial samples was developed to identify 14 oral microbiome features associated with oral diseases. Microbiome risk scores (MRSs) with the identified features were constructed with SHapley Additive exPlanations (SHAP). WebbFeature selection is an area of research of great importance in machine learning. At the end of the last century, when a special issue on relevance including several papers on variable and feature selection was published [1], very few domains used more than 40 features in their models ([2]). The situation has changed drastically over the years, due
