Feature Combination

A Feature Combination packages several features into one named, reusable set. It is the unit an experiment's HTE (Heterogeneous Treatment Effect) Analysis consumes — instead of attaching features one by one, you point the analysis at a single combination. Combinations live under Data Management → Feature Combination.

Where to find this in the console

Data Management → Feature Combination. The page has a search box (Search by keyword) and a Create button.

Columns shown

Column	What it shows
Feature Combination Name	The combination name.

The demo project ships one combination, Core Feature Set, described as the default bundle for HTE analysis — it includes country, device platform, player value tier, max level passed, and ad engagement.

Row actions

• Duplicate — copy the combination as a starting point for a new bundle.
• Log — open the Activity Log panel, which lists each change as operator + action (Create feature / Modify feature) + timestamp.
• Delete — remove the combination.

Create a combination

Create opens the Create Feature Combination dialog:

• Feature Combination Name (required) — accepts Chinese and English; the name must be unique.
• Description — a short note describing the bundle.
• Associated Features (required) — multi-select of existing features to include.

Confirm with Confirm or discard with Cancel.

When to use a combination

• The same set of features should drive HTE analysis across many experiments — define the bundle once and reuse it.
• You want a single object to govern, version, and audit (via Log) instead of several loose features.
