Struct Ucb1Config 

#[non_exhaustive]
pub struct Ucb1Config {
    pub exploration_constant: f64,
}

Available on crate feature bandit only.

Configuration for Ucb1.

Examples

use rill_ml::bandit::Ucb1Config;

let mut config = Ucb1Config::default();
config.exploration_constant = 2.0;
assert!((config.exploration_constant - 2.0).abs() < 1e-12);

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

exploration_constant: f64

Exploration constant c in the UCB formula. Controls the exploration/exploitation trade-off. Higher values favor exploration.

Must be finite and positive. With the formula used by this type, the classic UCB1 value is 1.0.

Implementations
