Input

A trained model operator to export.

Restrictions

Currently, the following model configurations are not supported for PMML (Predictive Model Markup Language) export.

  • SVM Classification: Only Hadoop SVM is supported for linear kernel type models (not Gaussian or polynomial).
  • Alpine Forest: Only Hadoop Alpine Forest model export is currently supported.

To enable the export of models to TIBCO® ModelOps, perform the following steps:

  1. The system administrator should add the following configuration to the alpine.conf file.

    modelops
    {
     enabled = true
     hostname = "modelops_hostname"
     https = true
    }
    Note:

    Replace the hostname parameter with the hostname of the TIBCO ModelOps instance. For example, hostname = "modelops-1.devmodelops120.streamingaz.tibcocloud.com"

  2. Restart the Chorus container.

Configuration

If the TIBCO® ModelOps is not configured, users have the following parameters.

Parameter Description
Notes Notes or helpful information about this operator's parameter settings. When you enter content in the Notes field, a yellow asterisk appears on the operator.
Export Format Format of the exported model.

  • Analytics Model Format (the default)
  • PFA
  • PMML
File Name The file name for the exported model.

Default value: @flow_name_model_0

For more information about the variables used for the default name, see Workflow Variables.

Ancestry Depth A value between 1 (the default) and 3, representing how many (supported) operators prior to the model should be exported when using Analytics Model or PFA formats.

If the TIBCO® ModelOps is available and configured, the following parameters are also available, in addition to those described above.

Export Location

Options:

  • Workspace (the default)
  • TIBCO ModelOps
Username The user name for your TIBCO® ModelOps account.

Default value: empty, but it can be configured by an administrator.

Password The password for your TIBCO® ModelOps account.

Default value: empty, but can be configured by an administrator.

Project Select a TIBCO® ModelOps project to store the exported model. The drop-down list includes all projects that are available to the user specified in the credentials above.
Overwrite? Choose whether to overwrite an existing model in the specified TIBCO® ModelOps project.

  • If Yes (the default) and the TIBCO® ModelOps Project has an existing model with the same name as specified in File Name, then AMS checks out the existing model and commits a new version.
  • If No, the operator fails with a warning that a model already exists in the project.

Output

Work file Output

The exported PMML (Predictive Model Markup Language), PFA (Portable Format for Analytics), or Analytics Model file is exported and saved as a work file within the current workspace, or in the specified project on the Artifact Management Server.
