Struct DecomposedPrediction

Source

pub struct DecomposedPrediction {
    pub location_base: f64,
    pub scale_base: f64,
    pub location_contributions: Vec<f64>,
    pub scale_contributions: Vec<f64>,
}

Expand description

Decomposed prediction showing each tree’s contribution.

Fields§

§location_base: f64

Base location prediction (mean of initial targets).

§scale_base: f64

Base scale prediction (log-sigma of initial targets).

§location_contributions: Vec<f64>

Per-step location contributions: learning_rate * tree_prediction. location_base + sum(location_contributions) = μ.

§scale_contributions: Vec<f64>

Per-step scale contributions: learning_rate * tree_prediction. scale_base + sum(scale_contributions) = log(σ).
