New framework views ML evaluation metrics as fair gambles

A new research paper proposes viewing machine learning evaluation metrics through the lens of game-theoretic probability. The authors demonstrate that many common metrics can be understood as averaged outcomes of fair gambles, where a fair gambler is expected to fail against a forecaster. This framework helps to categorize metrics into calibration-type and regret-type, revealing a theoretical equivalence in their evaluative power when appropriately scaled, despite the incomparability of their scores.
