pSeven 6.19 Release
DATADVANCE development team announces the release of pSeven 6.19, a new version of our flagship platform for data analysis and optimization.
New Features
- Added a more convenient way to set up leave-n-out cross validation in ApproxBuilder and the Model builder in Analyze in the manual configuration mode. Use the GTApprox/IVSubsetSize option to set n — for example, to perform leave-one-out cross-validation. Use the updated GTApprox/IVTrainingCount option to limit the number of model retraining sessions. See option descriptions for full details.
Updates and Changes
- Design space exploration block:
- Improved uniformity and variability of DoE generated by the Adaptive design technique in the uniform distribution mode (no adaptive responses) and in certain tasks with discrete variables.
- Predictive modeling:
- The GBRT technique now handles NaN values of variables in the training sample in a specific way. If you set the GTApprox/InputNanMode option, it keeps points where some (but not all) variables are NaN and actually uses them in training.
pSeven 6.19 also includes bugfixes – please see the release changelog for a full list. You can also contact us to get more information and pSeven updates.
