Struct CostMatrix 

pub struct CostMatrix {
    pub false_positive_cost: f64,
    pub false_negative_cost: f64,
    pub true_positive_cost: f64,
    pub true_negative_cost: f64,
}

Cost matrix for cost-sensitive evaluation.

Fields

false_positive_cost: f64

Cost of false positive

false_negative_cost: f64

Cost of false negative

true_positive_cost: f64

Cost of true positive (usually 0 or negative for reward)

true_negative_cost: f64

Cost of true negative (usually 0)
