#3087 accepted enhancement

Integrate Ceres with the native interpreter and extend features

Reported by: bburlacu Owned by: bburlacu
Priority: medium Milestone: HeuristicLab 3.3.x Backlog
Component: Problems.DataAnalysis.Symbolic.Regression Version: branch
Keywords: Cc:


We can use Eigen/Ceres inside the native interpreter and be able to:

  • use Eigen for evaluation
  • optimize model coefficients using nonlinear least squares
  • pass solver options to Ceres
  • get a report from the solver (successful steps, error, etc)

Change History (11)

r17844: Implement NativeInterpreter and ParameterOptimizer classes. The ParameterOptimizer offers an interface to Ceres and its options and to the variable projection optimization method. Added unit tests.

  • Status changed from new to accepted

r17853: Add accidentally omitted files.

r17989 updated native dlls for NativeInterpreter to a version that runs on Hive infrastructure. Some smaller changes because of deviations in the independently developed implementations (in particular enum types).

I have not tested this version for a few months.

TODO: the SymbolicDataAnalysisExpressionTreeNativeInterpreter can be deleted (replaced by NativeInterpreter) but first the inconsistencies between the two interpreters should be checked.
