Struct BatchUpperConfidenceBound 

pub struct BatchUpperConfidenceBound {
    pub batch_size: usize,
    pub kappa: f64,
}

Batch Upper Confidence Bound (q-UCB) using fantasized observations.

Similar to q-EI but uses UCB as the base acquisition function.

Fields

batch_size: usize

Batch size.

kappa: f64

Exploration parameter.

Implementations

impl BatchUpperConfidenceBound

pub fn new(batch_size: usize, kappa: f64) -> Self
