Managing Training Experiments

Training Experiment

Managing many training jobs can become challenging when trying to find or track them. Training experiments can simplify this process. This is a way to group similar jobs together. You can organize jobs into different experiments as needed, with each experiment holding multiple related jobs.

You can add one job to an experiment, create jobs within existing experiments, check the experiment list, view experiment details, or delete experiments as needed.

Adding a Training Job to an Experiment

To add a training job to an experiment, configure Experiment when creating a training job. The options are as follows:

• Create new: An experiment can only be created when you create a training job. If you select this option, enter a new experiment name. After the job is submitted, the experiment is created and the job is added to the new experiment. The experiment name will be checked. If the name is already in use, the job cannot be submitted.
• Use existing: Select an existing experiment from the drop-down list box to add the job to the existing experiment.

• Not required: Select this option if you do not want to manage your job through an experiment. The experiment tab on the training job management page only shows jobs that have been added to an experiment.

Creating a Job to Be Added to an Experiment

Log in to the ModelArts console, choose Model Training > Training Jobs, and click Create Training Job in the upper right corner.

On this page, set Experiment to Create new and enter a name for the new experiment. Then, an experiment is created after you create the training job.

Adding a Created Job to an Experiment

Log in to the ModelArts console, choose Model Training > Training Jobs, and click Copy in the Operation column of the target job. Alternatively, click the job name or ID in the job list. On the job details page, click Copy in the upper right corner.

• For a job that has not been added to an experiment, set Experiment to Create new and enter a name for the new experiment. Then, an experiment is created after you copy the training job.
• For a job that has been added to an experiment, set Experiment to Use existing and select the target experiment.
