0.1.0 - Apr. 04/07
|
||||
* ID3 algorithms for continuous and discrete cases
|
||||
* Graphviz component to visualize the learned tree
|
||||
|
||||
0.2.0 - Jul. 07/07
|
||||
* Modified and improved by Jose Ignacio (joseignacio.fernandez@gmail.com)
|
||||
* Added support for multiple, and symbolic outputs and graphing of continuos trees.
|
||||
* Modified to return the default value when no branches are suitable for the input.
|
||||
* Refactored entropy code.
|
||||
|
||||
0.3.0 - Sept. 15/07
|
||||
* ID3Tree can now handle inconsistent datasets.
|
||||
* Ruleset is a new class that trains an ID3Tree with 2/3 of the training data,
|
||||
converts it into a set of rules and prunes the rules with the remaining 1/3
|
||||
of the training data (in a C4.5 way).
|
||||
* Bagging is a bagging-based trainer (quite obvious), which trains 10 Ruleset
|
||||
trainers and when predicting chooses the best output based on voting.
