Structural Entropy vs. GC-comp. and MFE. 3D-plot of features MFE, Length and Structural Entropy of the training set sequences classifier under the RND model. Grid-view of different sets of sequences are shown in the top and Bottom views, riboswitches, E. coli UTRs, and antisense sequences. Axes R
D/L and M
E/L show Structural Entropy and MFE normalized by the length of the sequence, respectively. Euclidean distance to actual values was used to generate the grids.
