JAIR is pleased to announce the publication of the following article:

Quinlan, J.R. (1996)
  "Improved Use of Continuous Attributes in C4.5", 
   Volume 4, pages 77-90.

   Available in Postscript (414K) and compressed Postscript (124K).

   More detailed instructions are below.

   Abstract: A reported weakness of C4.5 in domains with continuous
   attributes is addressed by modifying the formation and evaluation of
   tests on continuous attributes.  An MDL-inspired penalty is applied to
   such tests, eliminating some of them from consideration and altering
   the relative desirability of all tests.  Empirical trials show that
   the modifications lead to smaller decision trees with higher
   predictive accuracies.  Results also confirm that a new version of
   C4.5 incorporating these changes is superior to recent approaches that
   use global discretization and that construct small trees with
   multi-interval splits.
