Struct PerformanceMetrics 

pub struct PerformanceMetrics {
    pub mitigation_overhead: f64,
    pub stability_score: f64,
}

Fields

mitigation_overhead: f64

stability_score: f64

Real, data-driven performance score in [0, 1], refreshed on every call to Self::update from the most recently mitigated measurements/gradients: 1.0 means measurements land tightly on ideal computational-basis outcomes and gradients are small/stable, 0.0 means measurements are maximally uncertain and gradients are large. Starts at 1.0 (optimistic / no adaptation needed) before any data has been observed.

Implementations

impl PerformanceMetrics

pub fn new() -> Self

pub fn update( &mut self, measurements: &Array2<f64>, gradients: &Array1<f64>, ) -> Result<()>

Recompute Self::stability_score (and a matching overhead proxy) from real, observed data: the empirical per-shot error rate of measurements (distance from the nearest ideal {0, 1} outcome) and the mean absolute magnitude of gradients (large gradients indicate an unstable, still-noisy optimization landscape).

pub fn current_performance(&self) -> f64

Trait Implementations

impl Default for PerformanceMetrics

fn default() -> PerformanceMetrics

Returns the “default value” for a type.
