Fig. 1From: Feature extraction with spectral clustering for gene function prediction using hierarchical multi-label classificationExample of global and local methods for hierarchical multi-label classification. Given a hierarchy of classes (r, a, b, c, d, e, and f), the dashed boxes show the number of classifiers required for each method. Note that the lcn, lcpn, lcl, and global classifiers require 6, 4, 3, and 1 predictors, respectivelyBack to article page
