Managing Training Job Versions

During model building, you may need to frequently tune the data, training parameters, or the model based on the training results to obtain a satisfactory model. ModelArts allows you to manage training job versions to effectively train your model after the tuning. Specifically, ModelArts generates a version each time when a training is performed. You can quickly get the difference between different versions.

Viewing Training Job Versions

  1. Log in to the ModelArts management console. In the left navigation pane, choose Training Management > Training Jobs. By default, the system switches to the Training Jobs page.
  2. In the training job list, click the name of a training job.
    By default, the basic information about the latest version is displayed. If there are multiple available versions, click Select Version in the upper left corner to view a certain version. Click the downward arrow to the left of the version to display job details. For details about the training job, see Training Job Details.

Comparing Versions of a Training Job

On the Version Manager page, click View Comparison Result to view the comparison of all or selected versions of the current training job. The comparison result involves the following information: Running Parameter, F1 Score, Recall, Precision, and Accuracy.

The F1 Score, Recall, Precision, and Accuracy parameters of a training job are displayed only when the job is created using a built-in algorithm. For training jobs created using frequently-used frameworks or custom images, define the output of these parameters in your training script code. These parameters cannot be viewed on the GUI.
