#2988 new feature request

Models of Models

Reported by: msemenki Owned by: msemenki
Priority: medium Milestone: HeuristicLab 3.3.16
Component: ### Undefined ### Version: branch
Keywords: Cc:


The main idea is to use Simple Symbolic Formulas generated offline with the help of the Fast Function Extraction Algorithm as building blocks for Genetic Programming. A map of building block’s set should be generated by means of clustering. All distances between blocks should be calculated offline by using a special metric for symbolic expressions. A mutation operator in Genetic Programming should be modified for work with this kind of map.

28/03/19 11:22:24 r16722: The first version of GP for Evolvement models of models was added.
The main parts:

  • new symbol and new node type,
  • modified grammars for working with the new symbol,
  • modified interpreter for working with the new symbol (SymbolicDataAnalysisExpressionTreeBatchInterpreter.cs),
  • the first variant of a map (EMMMapTreeModel.cs),
  • clustering algorithm for the map preparation (HeuristicLab.Algorithms.EMM/EMMClustering.cs),
  • a mutation that can use these building blocks (HeuristicLab.Algorithms.EMM/EMMMutators.cs),
  • the common algorithm that uses these stuff (HeuristicLab.Algorithms.EMM/EMMAlgorithm.cs).

01/04/19 13:03:13 r16734: Add Model Symbol Frequency Analyzer and Model's Clusters Frequency Analyzer. Fix Bags with Keys. Fix changing during mutation for Variables Types in SubModels. Add the possibility to write and read previously created maps.

04/04/19 14:33:12 r16760: Some new features were added:

  • new type of mutation that respect node type and do not change the trigonometric node to "add" node;
  • variation of previous mutation type that does not change the type of terminal node;
  • some interface adjusting for comfort work with the algorithm;
  • the second variant of the map, that is not "island" map but provide "net" map.
