Results
The neuron model of the mechanical system has manifested a high rate of success during the verification
by test sets. The network was taught with random selections of the test items. During testing of the
individual models, the responses of the network were successful in 85–95% of all cases (see Figs. 34.4
and 34.5). Moreover, the estimate of the values K and B that correspond to the parameters is available
within a couple of seconds for the frequency spectrum in the active mode. However, it is possible that a
model with higher quality will be achieved if special optimizing techniques are used in the future.
In summary, the neuron model of the mechanical system described above can be assessed as usable
in practical terms.
