Enum RidgeDeterminantMode 

pub enum RidgeDeterminantMode {
    Full,
    PositivePartApproximation,
}

Determinant semantics of an objective-accounted ridge.

There is deliberately no Auto: callers must decide whether they are evaluating the exact SPD determinant or a named positive-part approximation before constructing the policy.

Variants

Full

Exact full log-determinant of the ridged SPD matrix.

PositivePartApproximation

Smooth positive-part spectral determinant approximation. This changes the estimand and is therefore explicitly named as an approximation.
