lib/folder
- New subsampling, one-hot-encoding and cobweb plot functions now available in the
Enhancements
- General:
- Standardized the examples for improved readability
- Documentation:
- Added the outputs of
uq_printto all manuals - Added comments on the default values used in the minimal working examples
- General readability and consistency improvements
- Added the outputs of
- Reliability analysis module:
- AKMCS:
- Added a convergence criterion on beta
- IS:
- One instrumental density function can now be specified for each model output
- AKMCS:
- Sensitivity analysis module:
- Removed the requirement for an input object for SRC / Correlation-based sensitivity analyses when a sample is provided
Changes
- General:
- Changes in
uq_displayfor many modules to optimize readability
- Changes in
- Metamodeling modules:
- Polynomial chaos expansions:
- Default degree for Quadrature set equal to
3, for degree-adaptive methods to1:3 - Fixed issues that broke the evaluation of a quadrature PCE for multiple outputs models
- Initialization sets the maximum degree either from the provided degree or custom truncation. If both are provided, the custom truncation will be used.
- Stability fixes for arbitrary polynomials (fix for integration waypoints)
- Default degree for Quadrature set equal to
- Kriging:
- Specification
ExpDesign.Sampling = 'user'or'data'is no longer necessary when providing the samples manually - Removed
ExpDesign.timefrom results - Moved
ExpDesign.muXand.sigmaXfromResultstoInternal
- Specification
- Polynomial chaos expansions:
Bug fixes
- Reliability analysis module:
- SORM: can now be run on a pre-existing FORM analysis
- IS: Removed warning in initialization if no instrumental density distribution is provided
- Sensitivity analysis module:
- Small stability fixes to sensitivity- and PCE- related calculations
- Fixed the assembling of the PCE-based Sobol’ indices to avoid problems when using constant variables
- Fixed LRA-based Sobol’ indices to prevent failing for models with multiple outputs
- Sobol’ indices can be plotted as a pie-diagram
