-  stop growing tree earlier
 -  post-prune the tree
 -  separate set of examples - training and validation set approach
- even if the training set is mislead by random errors the validation
set is unlikely to exhibit the same random fluctuations - 2/3
training, 1/3 validation
 -  statistical test
 -  measure for complexity of encoding
