Task 2: Defining a machine learning provider in Decision Designer

You import and explore a new decision service. Then, you define a machine learning provider using Watson Machine Learning.

Step 1: Importing a sample decision service

You import a sample decision service into your decision automation. This decision service applies several criteria to determine a borrower’s loan eligibility. One key factor is risk, which is predicted by the machine learning model.

  1. Sign in to Decision Intelligence using your instance credentials.
  2. Create a decision automation.
  3. Click New decision +.
  4. Click Discovery tutorials and select Machine learning complete tutorial - Loan approval. Then, click Import.
  5. Open the Complete machine learning loan approval decision service.
  6. Explore the imported decision service:
    1. Open the Loan Validation Data data model in the Data tab to review the defined types. Note that the risk probabilities type is used by the predictive model.
    2. Navigate back to the decision service name in the breadcrumbs and open the Loan Validation Decision Model. This model determines whether a loan can be approved. One key decision is the Risk Score node, which currently uses a static value. You will update this to use a predictive model.

Step 2: Defining a machine learning provider

You associate a new machine learning provider with your decision automation to access the model deployed in Task 1. For more information about machine learning providers, see Managing local machine learning providers.

  1. Navigate back to your decision automation.
  2. Click the Settings Settings icon icon in the menu bar of your decision automation.
  3. Open the Machine learning providers tab.
  4. Click New + to create a provider:
    1. Type: Select WatsonX Machine Learning (IAM).
    2. Name: Enter wml-complete.
    3. Description: Enter Provider for the machine learning complete tutorial.
    4. Enter the following credentials obtained in Task 1:
      • API key
      • Space ID
      • URL
      • Authentication URL
  5. Click Save. Wait until the Status shows Running to confirm the provider is ready.
  6. Navigate back to your decision automation.
