the use of training sets that combine high change tiles with representative cluster members continue
to produce the best classification results. Precision and accuracy values hover around the 50% mark,
while overall accuracy is between 70–80% for the Columbia and Las Vegas datasets. The Natanz dataset
represents an anomaly, because of the relatively small amount of actual change in the dataset; precision
and recall values typically top out no higher than 30%, but overall accuracy is in the mid-90% range.
This occurs because the classifier is able to accurately predict a large number of true negative tiles within
this pair.
