Decision – New in Hub 4.5

Blue Prism® Decision provides Blue Prism users with the ability to train and deploy intelligent machine‑learning decision‑making models within their Digital Workforce, without requiring any data science expertise. Blue Prism Decision's simple and intuitive user interface allows users to:

  • Define a model – Add a title, description, decision type, and decision variables.
  • Train the model – Use active learning based on defined input variables specified by the model service, without needing any data science knowledge to produce statistically accurate machine‑learning models.
  • Calibrate the model – Review model inputs and outcome predictions, and overwrite model decisions if required.

Blue Prism Decision is a new license-controlled plugin available in 4.5. For more information, see Decision in the online help.

Blue Prism recommends that Decision is only installed if you have a mature understanding of IT policies around Docker Container infrastructure, as this release is dependent on installing both Hub and a Docker Container. The next release in 2022 will also be made available via an MSI.

Interact

For the Interact plugin improvements and fixes, see the Interact 4.5 release notes.
