Enum DriftDetector 

pub enum DriftDetector {
    Psi {
        threshold: f64,
    },
    KolmogorovSmirnov {
        p_value: f64,
    },

Drift detection strategy.

Variants

Psi

Population Stability Index with a configurable threshold (default 0.25).

Fields

threshold: f64

PSI threshold for drift detection.

KolmogorovSmirnov

Kolmogorov–Smirnov two-sample test with a configurable p-value significance level (default 0.05).

Fields

p_value: f64

Significance level for the KS test.

Adwin

ADWIN online adaptive windowing with a configurable delta (default 0.002).

Fields

delta: f64

ADWIN confidence parameter.

Implementations

impl DriftDetector

pub fn detect(&self, training: &[f64], current: &[f64]) -> DriftReport

Run drift detection.

• training: the reference distribution the model was trained on.
• current: the current/production data.

Trait Implementations

impl Clone for DriftDetector

fn clone(&self) -> DriftDetector

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DriftDetector

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

Formats the value using the given formatter.

impl Default for DriftDetector

fn default() -> Self

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for DriftDetector

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Serialize for DriftDetector

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

where __S: Serializer,

Serialize this value into the given Serde serializer.
