Changes in classification error in validation data sets with an
increasing number of iterations for artificial neural network models:
models were trained on data from Australian and South American sites
to predict disease severity class at South American (dotted line) and
Australian (solid line) sites, respectively; other models for Samford (),
Springmount (), Southedge (), Campo Grande (), Planaltina ()
and Carimagua () were trained on data for all sites except the site
being used for prediction.
