Figure 2

(a) Classification error as a function of the link density of the parenclitic networks. Black squares, black circles, and blue triangles, respectively, represent the error for the classification for the original raw features, for the classification using parenclitic features alone, and for the classification with all features. (b) Error reduction, in percentage, when using only parenclitic features (black circles) and the full set of features (blue triangles), with respect to the use of the raw data set.
