Rapids AI Scoring

The Rapids AI Scoring node performs Rapids AI Scoring by utilizing the columns of a data table as input to a trained classifier and adds columns containing predictions and associated probabilities of each class.

Prerequisites

  • An Execution Profile with an active session linked to the workflow

  • A model data frame generated by the Rapids AI node

Steps

  1. From the Machine Learning group of the Nodes tabbed page, drag and drop the Rapids AI Scoring node to the workflow canvas.

  2. Connect the output of the model to the Model socket and a new data table to the Table Socket of the Rapids AI Scoring node.

  3.  

  4. Configure the Rapids AI Scoring node by double-clicking the node or using the Open option provided in the node menu.

  5. The Rapids AI Scoring node configuration tabbed page displays columns from both the Model and Table side by side and the matching columns are auto mapped.

     

    You can manually select and map the appropriate columns from the Model and Tables lists if the names in the scoring table differ from those in the training table.

    You can rename the table name as well.  

  6. Click Save and Run.

  7. The Rapids AI Scoring Result object node is created with the scoring fields added to the original table.

     

    Double click the Scoring Result object node to view information such as Variable Information, Chart, Column metrics, and so on.

    The prediction columns that were not present in the test data set are now added to the Rapids AI Scoring node.
