pSeven 6.43 Release
pSeven development team announces the release of pSeven 6.43, a new version of our platform for data analysis and optimization. Take a look what's new in the release below.
New Features
Train models with input and output constraints — in the Build model dialog in Analyze, you can now specify valid input ranges and output thresholds for selected input and output components.
- Specify input ranges if you want to limit the model’s input domain. The trained model will output NaN if the input point is outside the domain (any input is out of the specified range).
- Specify output thresholds when it is known beforehand that output values must be within a certain range — for example, the output represents a physical quantity that cannot get below 0 by definition. The trained model adjusts to those thresholds so its output values are always within the specified thresholds.
Model constraints: for an input component, specifies its valid range; for an output component, sets its lower and upper thresholds. Input constraints limit the model’s input domain. The trained model will output NaN if the input point is outside the domain (any input is out of the specified range).
Output constraints are useful when it is known beforehand that output values must be within a certain range — for example, the output represents a physical quantity that cannot get below 0 by definition; in this case, 0 is the lower threshold. The trained model adjusts to such thresholds so its output values are always within the specified bounds.

Updates and Changes
- Predictive modeling: Removed the training data filter settings from the Build model dialog in Analyze as they are rarely used and may lead to confusion, since the actual training sample is not available in the report if you apply a data filter in the model training settings. It is recommended to use data filtering and export options in the Sample viewer instead.
- Uncertainty quantification block: In the reports generated by the FORM and SORM techniques, the convergence plot now uses logarithmic Y axis scale for better readability.
