New in Release 2.08
- Differential misclassification costs
-
See5/C5.0's handling of
misclassification costs
has been revised, particularly when the application
has more than two classes. Decision trees are pruned more carefully,
and the confidence of predictions is now calculated differently.
- Faster rulesets
-
Rulesets are now generated more quickly, especially for large applications.
For example,
the time to generate a ruleset for one dataset with 750,000 cases
was reduced by more than 10%.
- Bug fix: pruning
-
A minor bug that could affect pruning of decision trees has been corrected.
The problem could arise in applications with many attributes and a
large number of missing values. (This bug only trivially affected the
output of See5/C5.0 and had no noticeable impact on the trees'
predictive accuracy.)
