Control group configuration for predictions
Valid from Pega Version 8.5
You can now configure a control group for your predictions in Prediction Studio. Based on the control group, Prediction Studio calculates a lift score for each prediction that you can later use to monitor the success rate of your predictions.
For more information, see Customizing predictions.
Convert data instances into decision parameter rules
Valid from Pega Version 7.1.8
The Convert groups wizard is available in the Hierarchy landing page when the list of your propositions include decision data records.
Click Convert groups at the top of the landing page to use the wizard and to convert data instances into decision parameter rules. This conversion is necessary to make the existing proposition data instances available for revision management.
Response timeout configuration for predictions
Valid from Pega Version 8.5
You can now set a response timeout for your predictions in Prediction Studio. By setting a response timeout, you control how Prediction Studio registers customer responses that later serve as feedback data for your predictions.
For more information, see Customizing predictions.
Update text analytics models instantly through an API
Valid from Pega Version 8.1
Use the pxUpdateModels API to automatically retrain text analytics models for which you gathered feedback as a result of the pxCaptureTAFeedback activity. The pxUpdateModels API provides an option to update the model with the latest feedback without having to open Prediction Studio. Instead, you can use the activity from your application, for example, through a button control.
For more information, see Feedback loop for text analytics.
Data Flow transformation shapes cannot be used in combination with the Compose or Merge shapes
Valid from Pega Version 7.1.8
When you reference another data flow from a data flow that contains the Compose or shape, the referenced data flow cannot contain transformation shapes (, , ).
Data flow validation does not currently prevent you from designing a data flow that goes against this design pattern. Make sure that your data flows follow this design pattern by checking the referenced and referencing data flows.
Improved performance of decision strategies
Valid from Pega Version 8.1
Strategy rule performance has been improved through the implementation of a new engine. You can perform single and batch test runs to analyze strategy performance, locate and prevent potential issues, and optimize strategy components. Test runs now support data sets and data flows with multiple key properties. The redesigned Test run panel improves the display of information and highlights the most immediately relevant details.
