In the final series of ANN models, data from all Australian
and South American sites were pooled and models
were trained on data from five sites to predict the severity
class for the remaining sixth site. Of the six cross-continent
ANN models developed in this way, the model developed
without the data from Planaltina was the most accurate,
successfully predicting severity on >85% of days. The
ANN model without the Carimagua data correctly predicted
severity on only 54% of days at this site. The other
four models were accurate on >73% of days (Table 2).
The prediction errors of these models were considerably
higher than for the continent-wise ANN models (Table 1)
for all sites except Samford and Planaltina.
