Stream descriptions

For each stream that you create, IBM® SPSS® Modeler produces a stream description containing information on the contents of the stream. This can be useful if you are trying to see what a stream does but you do not have IBM SPSS Modeler installed, for example when accessing a stream through IBM SPSS Collaboration and Deployment Services.

The stream description is displayed in the form of an HTML document consisting of a number of sections.

General Stream Information

This section contains the stream name, together with details of when the stream was created and last saved.

Description and Comments

This section includes any:

  • Stream annotations (see Annotations)
  • Comments not connected to specific nodes
  • Comments connected to nodes in both the modeling and scoring branches of the stream

Scoring Information

This section contains information under various headings relating to the scoring branch of the stream.

  • Comments. Includes comments linked only to nodes in the scoring branch.
  • Inputs. Lists the input fields together with their storage types (for example, string, integer, real and so on).
  • Outputs. Lists the output fields, including the additional fields generated by the modeling node, together with their storage types.
  • Parameters. Lists any parameters relating to the scoring branch of the stream and which can be viewed or edited each time the model is scored. These parameters are identified when you click the Scoring Parameters button on the Deployment tab of the stream properties dialog box.
  • Model Node. Shows the model name and type (for example, Neural Net, C&R Tree and so on). This is the model nugget selected for the Model node field on the Deployment tab of the stream properties dialog box.
  • Model Details. Shows details of the model nugget identified under the previous heading. Where possible, predictor importance and evaluation charts for the model are included.

Modeling Information

Contains information relating to the modeling branch of the stream.

  • Comments. Lists any comments or annotations that are connected to nodes in the modeling branch.
  • Inputs. Lists the input fields together with their role in the modeling branch (in the form of the field role value, for example, Input, Target, Split and so on).
  • Parameters. Lists any parameters relating to the modeling branch of the stream and which can be viewed or edited each time the model is updated. These parameters are identified when you click the Model Build Parameters button on the Deployment tab of the stream properties dialog box.
  • Modeling node. Shows the name and type of the modeling node used to generate or update the model.
