Figure 8. Scatter graphs prepared for (a) training, (b) verification and (c) test data sets of
actual surface area and surface area estimated using TreeNet and ANN models
When the prepared scatter graphs are examined, it is seen that the data
are closer to the diagonal in the TreeNet method. As can be understood from
these graphs, the model developed using the TreeNet method gave results
closer to the actual surface area compared to the model developed using the
ANN method.
