What the math gives to ML
The paper’s transferable contribution is a binary testing reduction that keeps false-positive and false-negative targets separate instead of combining them into one error probability. This suggests a practical calibration objective for safety classifiers, OOD detectors, abstention gates, and reward models with asymmetric risk requirements. The most useful adaptation is to impose independent empirical constraints on type-I and type-II errors, while using the resulting directed KL and Jeffreys divergences as a separation regularizer for the model’s scalar score.

Add a calibration loss that explicitly enforces independently prescribed false-positive and false-negative targets rather than optimizing symmetric accuracy or cross-entropy alone. Apply it to binary classifiers, OOD detectors, safety heads, or abstention gates, and use the binary Jeffreys divergence to encourage robust separation between null and alternative score distributions.
