Ranking is based on absolute mean relevance values across all samples per classifier. Species are ordered according to the number of classifiers by which they were top-ranked. All - all classifiers; svm - linear SVM; rf - Random Forest; nsc - Nearest Shrunken Centroids; lr - L2-regularized Logistic Regression
