Struct LinUcbArmScore 

pub struct LinUcbArmScore {
    pub arm: usize,
    pub exploitation: f64,
    pub exploration_bonus: f64,
    pub total_score: f64,
}

Available on crate feature bandit only.

Explainable score components for one LinUCB arm.

exploration_bonus already includes the configured alpha multiplier, so total_score = exploitation + exploration_bonus.

Fields

arm: usize

Zero-based arm index.

exploitation: f64

Estimated reward theta_a^T x.

exploration_bonus: f64

Confidence bonus alpha * sqrt(x^T A_a^-1 x).

total_score: f64

The exact score used by selection.
