8. Discover and Create Features with FeatureByte Copilot

FeatureByte offers two primary methods for feature creation:

Manually: Utilize the SDK declarative framework
Automatically: Employ FeatureByte Copilot

In this tutorial, we'll focus on automatic feature creation using FeatureByte Copilot.

Note

If you want to learn how to manually create features, please consult our SDK tutorials.

Step 1: Select Your Use Case¶

Navigate to Feature Ideation from the Create section of the menu.

Choose the use case: "In-Store Prediction of Customer Spending on a given Product Group next 2 Weeks".

Step 2: Run Semantics Detection¶

Click "Run Semantics Detection" to let FeatureByte identify and tag relevant tables and data columns.

Name

If the columns aren’t tagged correctly, check the suggested tags and make adjustments.

Note

The accuracy of suggestions improves with more detailed data descriptions. Refer to our tutorial "Add descriptions and Tag Semantics" to update table and columns descriptions.

Step 3: Initiate Feature Ideation¶

Start the Feature Ideation process by clicking "Start Feature Ideation".

Step 4: Evaluate Feature Engineering Strategy¶

Review Copilot’s data aggregation and filtering suggestions.

Note

Not all use cases require filtering. In some scenarios, like the one in this example, filtering might be unnecessary.

Filtering becomes relevant when specific types of columns, such as "event type" and "event status," are present. For instance, in Credit Card Transactions, you might encounter columns indicating transaction type (e.g., "Purchase", "Cash Advance", "Reversal", ...) and transaction status (e.g., "Authorized", "Rejected", "Cancelled"). In such cases, Generative AI will recommend filters that are pertinent to the specific use case.
