From: Differentiating Thamnocalamus Munro from Fargesia Franchet emend. Yi (Bambusoideae, Poaceae): novel evidence from morphological and neural-network analyses

Figure 5

Trained classification structure model (A) and weight structure (B,C and D) of the SOM neural network. We converted the 46 morphological characters into normalized vectors of codon usage x(t), and 32 accessions were classified by character factors. Symmetrical effects and differences among the samples are more obvious and significant, although off-diagonal weight points are observed.
