Score

Score Node icon

The Clario Score node is used to score a data stream with either a linear or logistic regression model. There are two data inputs to Score. First, you need the results of either a Linear Regression or Logistic Regression node. Connect a Linear or Logistic node to the upper input connector. Or, if you’ve written the results to a file using a Write File node, connect a Read File node referencing the appropriate results file to the upper input connector. A properly formatted results file is comprised of 3 fields: COMPONENT, DESCRIPTION, and VALUE.

The following example illustrates one possible logistic result that could be read into a Score node.

Once the results are connected to the upper input connector, you need the data stream you wish to score, that contains all of the predictor attributes. Connect the data stream to the lower input connector.

Configuration

Score has only one configuration tab.

Configuration Tab

Configuration Tab

The only user input for Score is the name of the model score attribute. Simply type this into the text box provided. See tips on Valid Characters for Attribute Names. If invalid keys are pressed when the text box is open, nothing will appear.

Results

There is one results set with one tab (Model Score Equation) for the Score node. The Model Score Equation tab is used to process your input data stream and compute the Model Score Attribute.

Output Stream

The data output stream from the Score node contains the original data stream with the addition of one attribute, the score attribute you named on the configuration tab. You can connect the Score node to a Write File node to write out a dataset, or to a number of other nodes to continue processing.
