An experiment domain can contain one or more experiment layers. Each experiment layer carries all the traffic of the experiment domain. In an experiment domain, the traffic between all experiment layers is mutually independent, and the parameters associated with the experiment layers are mutually exclusive. This topic describes how to create and manage an experiment layer.
Prerequisites
An experiment project is created. For more information, see Create an experiment project.
Create an experiment layer
Go to the ABTest page.
Log on to the PAI console.
In the left-side navigation pane, click Workspaces. On the Workspaces page, click the name of the workspace that you want to manage.
In the left-side navigation pane, choose .

Parameter
Description
Name
The name of the experiment layer.
Description
The description of the experiment layer.
Experiment Project
Select an experiment project from the drop-down list. If no experiment project is available, click Create Project to create an experiment project.
Experiment Domain
You can select an experiment domain only after you select an experiment project. Select an experiment domain from the drop-down list. If no experiment domain is available, click Create Experiment Domain to create an experiment domain.
Click OK.
Manage an experiment layer
After you create an experiment layer, you can view the experiment layer in the experiment layer list and perform the following operations on the experiment layer.

Modify the experiment layer.
Click Edit in the Actions column to modify the description.
Delete the experiment layer.
Click Delete in the Actions column to delete the experiment layer that you no longer use.
