Fig. 8.5 Distribution of the formalistic items
8.4.2 Formalistic Items Distribution
The overall output distribution graph of formalistic items is shown in Fig. 8.5. The
directions of the two axis of X and Y are respectively named Round-Flat and PressedPulled. These given names are based on the context and distribution of the items in
the graph. Also this analysis was done for samples to show the distribution of samples
according to characteristic formalistic items.
8.4.3 Samples Formalistic Distribution and Clusters
To classify the samples according to their formalistic features, the linkage distance
across fusion steps may help (Milligan and Cooper 1985). The axis directions have
been named Round-Flat and Pressed-Pulled according to the distribution of formalistic items. In a same formalistic distribution of the cars, the names of axes suggested
by Abdulrahman et al. are “round-boxy” and “heap-disperse” (Rahman et al. 2013).
As the formalistic items and our given names to the axes are so close to the abovementioned research, the same names with some changes for X and Y axes are used
in these research: Round Face—Boxy Face and Heap—Disperse.
The chosen cut-off for the clustering algorithm has yielded five clusters Fig. 8.6,
which marked from CL1 to CL5. The cut-off line is made to have meaningful
groupings for understanding of the relationship between various vehicles.
