Struct LinUcbConditionDiagnostics 

pub struct LinUcbConditionDiagnostics {
    pub arm: usize,
    pub min_cholesky_diagonal: f64,
    pub max_cholesky_diagonal: f64,
    pub condition_indicator: f64,
}

Available on crate feature bandit only.

Numerical diagnostics for one LinUCB arm’s ridge matrix.

Fields

arm: usize

Zero-based arm index.

min_cholesky_diagonal: f64

Smallest diagonal entry of the Cholesky factor.

max_cholesky_diagonal: f64

Largest diagonal entry of the Cholesky factor.

condition_indicator: f64

A cheap condition indicator (max_diag / min_diag)^2.

This is not an exact matrix condition number, but a large value is a useful signal that the arm state is becoming poorly conditioned.
