Work with AI Catalog assets¶

Search for a specific asset using the search query box.

Use the dropdown to modify the order of all existing assets.

The default sort option is Creation date, except after searching for a specific asset, in which case the default is Relevance.

Under the search query box, you can filter assets by Source, Tags, and/or Owner.

For example, you can filter by any tags manually added to an asset:

The Info tab displays an overview of the asset's details as well as metadata.

	Element	Description
	Name	Name the asset. By default, this is the file name uploaded.
	Description	Enter a helpful description of the asset.
	Tags	Add tags to help when filtering assets in the AI Catalog. DataRobot offers any predefined tags that match the characters you entered. Select one by clicking or continue typing to add a new tag of alphanumeric characters (special characters and symbols are invalid). Either click outside the entry box or in the dropdown to add the tag.
	Overview	An overview of the asset, including the full row count, feature count, and feature types.
	Metadata	Additional metadata, including size, owner, and dataset ID.

Click the pencil icons () to change the asset name, add a description, or add tags to aid in filtering, and then click anywhere outside of the box to save the change.

The Profile tab allows you to preview dataset column names and row data. It can be useful for finding or verifying column names when writing Spark SQL statements for blended datasets.

Note that the preview is a random sample of up to 1MB of the data and may be ordered differently from the original data. To see the complete, original data, use the Download Dataset option.

To preview a dataset, select it in the main catalog and click the pencil icon () to access dataset information (if available).

1. Click the Profile tab to preview the contents of the dataset:

   

2. Use the Columns dropdown to select the number of columns to display on the page and the scroll bars to scroll through those columns. Additionally, you can use the Rows dropdown to cycle through available data, 20 rows at a time.

The Profile tab also displays details for all features in the dataset. To view details for a particular feature, scroll to it in the display and click. The Feature Details listed in the right panel update to reflect statistics for the feature. (These are the same statistics as those displayed on the Data for EDA1.)

You can create new lists and feature transformations for features of any dataset in the catalog. To work with the tools, select the dataset in the main catalog and Feature Lists in the left panel.

When you create feature lists, they are copied to a project upon creation. You can then set the list to use for the project from the Feature List dropdown at the top of the Project Data list. See the section on working with Feature Lists for complete details on creating, modifying, and understanding these lists.

The Feature List tab also provides access to a tool for creating variable type feature transformations. While DataRobot bases variable type assignments on the values seen during EDA, there are times when you may need to change the type. Refer to feature transformations documentation for complete details.

To create a feature list:

1. Use the checkboxes to the left of feature names to select a set of features.

2. Click the Create new feature list from selection link, which becomes active after you select the first feature.

   

3. In the resulting dialog, provide a name for the new list and click Submit. The new list becomes available through the dropdown.

You can delete or rename any feature list you created. You cannot make any changes to the DataRobot default feature lists.

DataRobot’s Feature Discovery capability guides you through creating relationships, which define both the included datasets and how they are related to one another. The end product is a multitude of additional features that are a result of these linkings. The Feature Discovery engine analyzes the included datasets to determine a feature engineering “recipe” and, from that recipe, generates secondary features for training and predictions. Once these relationships are established, you can view them from the catalog.

To view relationships, select the dataset in the main catalog and click the Relationships tab to view, modify, or delete existing relationships:

See complete details of working with relationships before modifying relationship details.

The Version History tab lists all versions of a selected asset. The Status column indicates the snapshot status—green if successful, red if failed, gray if the original version did not have a snapshot.

Click a version to select it. Once selected, you can create a project from the version and download or delete the contents.

The Comments tab allows you to add comments to—even host a discussion around—any item in the catalog that you have access to. Comment functionality is available in the AI Catalog (illustrated below), and also as a model tab from the Leaderboard and in use case tracking. With comments, you can:

• Tag other users in a comment; DataRobot will then send them an email notification.
• Edit or delete any comment you have added (you cannot edit or delete other users' comments).
