    • The ClusteringSolution API is a scriptable object used in Predictive Intelligence stores.

    This API requires the Predictive Intelligence plugin (com.glide.platform_ml) and is provided within the sn_ml namespace.

    The solution setup-to-training flow is as follows:
    1. Create a dataset using the DatasetDefinition API.
    2. Use the constructor to create a clustering solution object.
    3. Add the solution object to the clustering solution store using the ClusteringSolutionStore - add() method.
    4. Train the solution using the submitTrainingJob() method. This creates a version of the object that you can manage using the ClusteringSolutionVersion API.
    注:
    This API runs with full privileges before the Vancouver Patch 7 Hotfix 2b and Washington DC Patch 7 releases. With later releases, grant access using ACLs. For more information see Query ACLs.

    For usage guidelines, refer to Using ML APIs.
