Data¶

The Data tab lists all datasets currently linked to the selected Use Case by you and other team members. To access this tab, open a Use Case and click Data.

From this tab, you can:

Explore data¶

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:

1. In a Use Case, navigate to the Data tab.

2. Click the More options icon next to the dataset you want to view and select Explore. Alternatively, click the dataset name to view its insights.

   

3. For each feature in the dataset, DataRobot displays various feature details, including a histogram and summary statistics.

   

4. To drill down into a specific feature, click its histogram chart along the top.

   

Data explore page¶

The data explore view, accessed by clicking Explore in more options () on the right of a dataset, includes the following improvements to profile and work with your datasets:

• View a version history of the dataset that displays all snapshot datasets created from the live data, allowing you to easily work with and view multiple dataset versions from the same page.
• The Feature list tab provides a dedicated page to work with feature lists.

Dataset versioning¶

The data explore page supports dataset versioning, allowing you to access a history of data snapshots as well as create new snapshots from the same page. To access dataset versions, click the dropdown next to Data actions or open Dataset Versions in the right panel.

Feature list view¶

The Feature list view replaces the dropdown with a dedicated page to view, manage, and create feature lists.

To control the columns displayed here, click Settings and select the box next to the columns you want to view. Then, click Apply.

Dataset actions¶

From the data explore page, you can perform the following actions:

Feature lists¶

After adding a dataset to your Use Case, DataRobot generates feature lists as part of EDA. Feature lists control the subset of features that DataRobot uses to build models and make predictions. Each model has a feature list associated to it.

You might want to use feature lists to:

• Remove features that cannot be used in the model for any reason, for example, a feature that is causing target leakage.
• Make predictions faster by removing unimportant features (i.e., ones that don't improve the model's performance).

You can use one of the automatically created lists—Informative and Raw—or create a custom feature list.

View feature lists¶

Before setting up an experiment, use exploratory data insights to explore different feature lists before choosing the appropriate one to use for modeling.

To explore insights for a feature list:

1. In the Data tab, click the More options icon next to the dataset you want to view and select Explore. Alternatively, click the dataset name.

   

2. To access your feature lists, click the dropdown at the top of the page and select an available feature list. The preview updates to show only the features in the selected list.

   

Create a feature list¶

To create a custom feature list:

1. While exploring a dataset, click the dropdown at the top of the page and select + New feature list. This opens the Features view.

   

2. Select the box next to each feature you want to include in your custom list. Then, click Create feature list.

   

3. Enter a name and description (optional) for the new feature list.

   

4. Click Save changes. You can now access the new feature list in the dropdown.

Next steps¶

From here, you can:

• Add more data.
• Perform data wrangling for datasets added via a data connection.
• Use the dataset to set up an experiment and start modeling.
