Improved data-analytical tools are needed to exploit all information from these biological datasets, taking into account the peculiarities of microbiome data, i.e., compositional, heterogeneous and sparse nature of these datasets. Microbiome risk scores (MRSs) with the identified features were constructed with SHapley Additive exPlanations (SHAP). There are two main paradigms used in microbiome research: unsupervised learning (learning from unlabelled data) and supervised learning (learning from labeled data). Microbiome.
