This page describes how to tune, pause, resume, delete, and list recommendation models. For help with creating a new recommendation model, see Create recommendation models.
Tune a model
Discovery for Media Recommendations uses the input data you provide to your model to adjust hyperparameters for training.
Tuning takes 2-4 days, during which the model continues to work as usual. For tuning cost details, see Pricing.
Set a model's tuning frequency
We recommend you periodically tune your model. This keeps model training optimal as data changes and customer behavior differs throughout the year. In addition, some internal major model upgrades can only be applied after the model has been tuned.
When creating the model, you can set it to automatically tune every three months, or choose to only tune it manually. Regardless of the setting you choose, the model automatically tunes one time after creation.
You can change the tuning status setting at any time. Changing this setting doesn't affect currently running tuning processes.
To edit a model's tuning status setting:
Go to the Discovery Engine Models page in the Google Cloud console.
Go to the Models pageYou can see the tuning status of every model under Tuning status.
Click a model name to view its details page.
Click Edit edit next to Tuning status.
From the drop-down list, select a setting:
- Every three months. Automatically tunes when the last tune was 90 days ago.
- Manual tune only. Tunes only when you manually tune.
Click Done done to save your setting.
Manually tune a model
Manual tune triggers a one-time tune of your model. You might manually tune your model when there is a significant change in your datastore (such as size increase or change in hierarchy) or events (such as backfilling historical events or a change in data distribution after promoting certain groups of items).
To manually tune a model:
Go to the Discovery Engine Models page in the Google Cloud console.
Go to the Models pageClick a model name to view its details page.
Click Manual Tune in the button bar.
Tuning takes 2-4 days, during which the model continues to work as usual.
Pause and resume training for a model
If your model is active (not paused), the model is trained at least once a week, but no more often than once a day. For consistent retraining, make sure that you upload user event data no more than 24 hours after the event occurs.
You can pause your model to stop retraining. You might want to do this if you have imported bad data or to stay under the limit of 10 active models per project. If you have fewer than 10 active models, you can restart a paused model at any time.
For training cost details, see Pricing.
You can start up to 5 model operations per minute. Limited model operations include creation, deletion, pause, and resume.
To pause or restart a model:
Go to the Discovery Engine Models page in the Google Cloud console.
Go to the Models pageYou can see the training status of every model under Training status.
To pause an active model (Training status of TRAINING), click Pause pause.
To start a paused model (Training status of PAUSED), click Resume play_arrow.
List your models
To see a list of all of your models, including their training and query status and settings, go to the Models page.
Delete a model
You can start up to 5 model operations per minute. Limited model operations include creation, deletion, pause, and resume.
You delete a model by opening its details page from the models list.
Go to the Discovery Engine Models page in the Google Cloud console.
Go to the Models pageClick the name of the model you want to delete to open its details page.
Click Deletedelete in the button bar.
Reenter the model name and click Confirm.
