Optunity provides a variety of solvers for hyperparameter tuning problems. The software offers a diverse set of solvers to optimize hyperparameters.

The first major release of Optunity (stable). For documentation, please refer to Optunity is compatible with Python 2.7 and above.

The following features are available:

Wide variety of solvers:

  • particle swarm optimization
  • Nelder-Mead
  • grid search
  • random search
  • CMA-ES (requires DEAP and NumPy)

Generic cross-validation functionality:

  • support for strata and clusters
  • folds are reusable for multiple learning algorithm/solver combinations

Various quality metrics for models (score/loss functions).

Univariate domain constraints on hyperparameters.

Support for parallel objective function evaluations.

This release provides Optunity functionality in the following environments: MATLAB R

Changes to previous version:

Bugfixes related to Python 3. Added smoke tests for all solvers to prevent similar issues in the future.
