Struct EpsilonGreedyConfig 

#[non_exhaustive]
pub struct EpsilonGreedyConfig {
    pub epsilon: f64,
    pub decay: f64,
    pub min_epsilon: f64,
}

Available on crate feature bandit only.

Configuration for EpsilonGreedy.

Examples

use rill_ml::bandit::EpsilonGreedyConfig;

let mut config = EpsilonGreedyConfig::default();
config.epsilon = 0.1;
config.decay = 0.999;
config.min_epsilon = 0.01;
assert!((config.epsilon - 0.1).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.

epsilon: f64

Initial exploration probability. Must be in [0, 1].

0.0 means pure exploitation, 1.0 means pure exploration.

decay: f64

Exponential decay factor applied to epsilon after each update.

Set to 1.0 for no decay (fixed epsilon). Must be in (0, 1]. After each update, epsilon becomes max(min_epsilon, epsilon * decay).

min_epsilon: f64

Lower bound for epsilon after decay. Must be in [0, epsilon].
