Enum CalibrationState 

pub enum CalibrationState {
    Calibrated {
        theta_hat: f64,
        rho: f64,
    },
    Stale {
        backoff_theta: f64,
        last_theta: f64,
    },
}

Calibration state of the conformal threshold.

Variants

Calibrated

Calibrated and exchangeable: the conformal bound may be asserted.

Fields

theta_hat: f64

rho: f64

Stale

Stale: exchangeability broken. The bound is NOT asserted; a back-off threshold applies and recalibration runs in the background.

Fields

backoff_theta: f64

last_theta: f64

Implementations

impl CalibrationState

pub fn calibrate(samples: &[CalibrationSample], rho: f64) -> Result<Self>

Build a calibrated state from samples.

pub fn mark_stale(&self) -> Self

Transition to a stale state with a conservative back-off (the threshold is inflated toward 1.0 to accept fewer candidates).

pub fn bound_is_asserted(&self) -> bool

Whether the conformal accepted-unsafe bound may currently be asserted. Only true while calibrated and exchangeable (PSP-8 System 7).

Trait Implementations

impl Clone for CalibrationState

fn clone(&self) -> CalibrationState

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for CalibrationState

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for CalibrationState

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for CalibrationState

fn eq(&self, other: &CalibrationState) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Serialize for CalibrationState

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
