Struct CalibratorCore 

Source 
pub struct CalibratorCore { /* private fields */ }
Expand description

Lightweight online calibrator that rescales a base 256-way PDF by context/bin.

The calibrator keeps per-context logits over probability bins and applies an exponential tilt p' ∝ p * exp(w_bin) followed by normalization.

Implementations§

Source§

impl CalibratorCore

Source

pub fn new( context: CalibrationContextKind, bins: usize, learning_rate: f64, bias_clip: f64, ) -> Self

Create a calibrator with bounded bin count and stable learning parameters.

Source

pub fn apply_pdf(&mut self, base: &[f64], out: &mut [f64])

Apply the learned calibration transform to base, writing a normalized PDF to out.

base/out are expected to be 256-byte distributions.

Source

pub fn update(&mut self, symbol: u8, calibrated_pdf: &[f64])

Update the active bin weight from the observed symbol and calibrated distribution.

Source

pub fn reset_context(&mut self)

Reset only the dynamic context state while preserving fitted weights.

Source

pub fn update_context_only(&mut self, symbol: u8)

Advance context state without updating fitted calibration weights.
