Overview
An analysis pattern that aggregates evaluation metrics across multiple application versions into a comparison leaderboard for systematic quality assessment.
Description
Leaderboard Analysis provides a programmatic way to compare multiple application versions by their aggregate feedback scores. The leaderboard computes mean scores for each feedback function across all records for each app version, producing a DataFrame ranked by quality.
This enables data-driven decisions about which application version to deploy, and supports A/B testing and iterative improvement workflows.
Usage
Use this principle after recording multiple application versions with the same feedback functions. Query the leaderboard to compare versions programmatically or view it in the dashboard.
Theoretical Basis
Leaderboard Analysis implements a Statistical Aggregation pattern over evaluation results, computing per-version summary statistics to enable cross-version comparison.
