Explore data¶

The Data assets tile lists all datasets and recipes currently linked to the selected Use Case. From here, you can manage your assets and launch various data actions:

	Element	Description
1	Add Data	Click to open the Add data modal, allowing you to add datasets to the current Use Case.
2	Search	Search for a specific dataset.
3	Asset type icons	Each asset is preceded by one of the following icons: : Indicates that the asset is a registered dataset. : Indicates that the asset is a wrangling recipe.
4	Actions menu	Click the Actions menu to interact with a data asset. For datasets you can: Edit dataset name: Rename the dataset. Explore: View exploratory data insights and manage feature lists. Wrangle/Continue Wrangling: Perform data wrangling on datasets retrieved from a data connection. Feature Discovery: Perform Feature Discovery when working with two or more datasets. Start modeling: Set up an experiment using the dataset. Remove from Use Case: Remove the dataset from the Use Case, also removing access for any team members. The dataset is still available via the Data Registry. For recipes you can: Edit: Modify the wrangling recipe. Clone: Create a duplicate entry of the wrangling recipe. Remove from Use Case: Remove the recipe from the Use Case.
5	Sort	Sort the dataset columns.

While a dataset is being registered in Workbench, DataRobot also performs exploratory data analysis (EDA1)—analyzing and profiling every feature to detect feature types, automatically transform date-type features, and assess feature quality. Once registration is complete, you can explore the information uncovered while computing EDA1.

To open the data explore page, click the Actions menu next to the dataset you want to view and select Explore. Alternatively, click the dataset name to view its insights.

Select version: Opens Dataset Versions in the right panel.
2	Dataset Versions	Displays a version history of the dataset. Click a dataset to view a different version.
3	+ Create snapshot / Upload new version	Allows you to add additional versions of the dataset, and after registration is complete, the new dataset is displayed in the version history. Additionally, it is added to the Use Case and Data Registry. If the snapshot policy of the original dataset is dynamic or snapshot,the + Create snapshot button is available, which creates a snapshot of the dataset you're viewing. If the original dataset is static (i.e., uploaded as a local file), the Upload new version button is available, which allows you to upload updated local versions of the dataset.

Data actions for snapshot policies

The data explore page supports the following snapshot policies:

Dynamic: DataRobot is connected to the data source and uses live data to perform the selected data action.
Snapshot: A fixed snapshot that is stored in DataRobot and used to perform the selected data action. This policy is recommended for repeatable experimentation if live data often changes.
Static: A local file used to perform the selected data action.

Data actions¶

You can perform the following actions on the data explore page (note that these actions persist no matter what view is currently selected):

	Element	Description
1	Dataset name	To rename the dataset, click on its name. To save your changes, click outside of the text field.
2	Data actions	Open the Data actions dropdown to perform one of the following actions with the dataset you're currently viewing: Start wrangling: Perform data wrangling on the dataset. Only available for dynamic datasets. Start modeling: Set up an experiment using the currently selected dataset version. By default, the latest version of the dataset is used. Start feature discovery: Use Feature Discovery to perform multi-dataset, interaction-based feature creation Download dataset: Download the dataset locally. Only available for snapshotted datasets. Remove dataset: Remove the dataset from the Use Case. It will no longer be visible on the Data tab, however, it will be available in Data Registry and will not affect experiments created with the dataset.
