Struct FeedbackDrivenFactor 

pub struct FeedbackDrivenFactor { /* private fields */ }

EWMA-driven correction factor for a single estimated value.

Implementations

impl FeedbackDrivenFactor

pub fn new(estimated: f64) -> Self

Create a factor for estimated with default parameters.

pub fn with_params( estimated: f64, alpha: f64, min_correction: f64, max_correction: f64, ) -> Self

Create a factor with custom parameters.

pub fn estimated(&self) -> f64

The uncorrected estimate.

pub fn set_estimated(&mut self, estimated: f64)

Track a fresh uncorrected estimate while preserving the learned correction factor and feedback history.

pub fn corrected(&self) -> f64

The corrected value: estimated * correction_factor.

pub fn correction_factor(&self) -> f64

The current correction factor.

pub fn feedback_count(&self) -> u64

Number of feedbacks received.

pub fn estimation_confidence(&self) -> f64

Confidence in the correction, based on the feedback count.

Sigmoid in the feedback count; close to 0.9 at 100 feedbacks.

pub fn avg_estimation_error(&self) -> f64

Average estimation error of the correction factor.

pub fn error_std_dev(&self) -> f64

Standard deviation of the correction-factor errors.

pub fn update_with_ratio(&mut self, ratio: f64)

Update the correction factor from an observed estimated-vs-actual ratio (actual / estimated), smoothed with EWMA.

pub fn reset(&mut self)

Reset the correction.

pub fn set_alpha(&mut self, alpha: f64)

Set the EWMA smoothing factor.

pub fn set_correction_range(&mut self, min: f64, max: f64)

Set the correction range.
