Struct DecayTerm 

pub struct DecayTerm {
    pub feature: ScoreFeature,
    pub half_life: f64,
    pub min_factor: f64,
}

Exponential decay 0.5^(age / half_life) over a distance or timestamp feature, clamped to [min_factor, 1] and multiplied into the combined score.

Fields

feature: ScoreFeature

half_life: f64

min_factor: f64
