Model evaluation is the next step in the model lifecycle when you evaluate a trained model using the test dataset. The test dataset is used to see how well the model performs on data it has not seen earlier.

Model evaluation generates an evaluation report that displays a number of metrics to monitor the model performance. The details of the evaluation report are discussed in the following section.

If the "Enable Model Evaluation" option is not selected for BYOM model, the Model Evaluation step will not be available on the Model Lifecycle page. In that case, you can directly go to the Approval step after Training the model version.
  1. On the Model Version Lifecycle page, select Evaluate.
  2. In the Basic tab, set the following properties:
    Property Description
    Model The name of the model in read-only format.
    Dataset Template Specifies the required dataset template.

    For details, see Dataset Templates.

    Dataset Specifies the dataset to be used for evaluation job.

    For details, see Datasets.

  3. In the Advanced tab, set the following properties:
    Property Description
    Engine Specifies the engine to evaluate the model.
    Docker Image Specifies the docker image to be used to run evaluation script.
    Resource Template Allows you to use a predefined set of resources, including CPU and memory, which are the properties of the container created to run evaluation script in.

    Select S Standard, M Medium, L Large or Custom from the dropdown list.

    With Custom selection, there are three additional Properties:
    • Memory: Free text to specify memory resource.
    • CPU: Free text to specify container CPU resource.
    • GPU: Specifies the GPU resource for the container.
  4. Select Evaluate Model.

    Dataset ID Displays the testing dataset ID used to evaluate the job.

    You can select View Dataset Statistics and View Dataset to see the dataset details. For details, see Datasets.

    Dataset Name Displays the testing dataset name used to evaluate the job.
    Resources Specifies the resources utilized in the evaluation job including CPU and Memory.
    Job Progress Lists down all phases of the evaluation job. The job progress information includes:
    • Status: Status of each phase as Created, Scheduled, Running, Evaluated, Completed
    • Start Date: Start date and time for each phase
    • End Date: End date and time for each phase
