    • Quinlan went on to create C5.0 and See5 (C5.0 for Unix/Linux, See5 for Windows) which he markets commercially. C5.0 offers a number of improvements on C4.5. Some of these are: [1] [2]
      • Speed - C5.0 is significantly faster than C4.5 (several orders of magnitude)
      • Memory usage - C5.0 is more memory efficient than C4.5
      • Smaller decision trees - C5.0 gets similar results to C4.5 with considerably smaller decision trees.
      • Support for boosting - Boosting improves the trees and gives them more accuracy.
      • Weighting - C5.0 allows you to weight different cases and misclassification types.
      • Winnowing - a C5.0 option automatically winnows the attributes to remove those that may be unhelpful.
    • Source for a single-threaded Linux version of C5.0 is available under the GPL.
  • Is See5/C5.0 Better Than C4.5?
