Struct LinUcbConfig 

#[non_exhaustive]
pub struct LinUcbConfig {
    pub alpha: f64,
    pub arm_count: usize,
    pub feature_count: usize,
}

Available on crate feature bandit only.

Configuration for LinUcb.

Examples

use rill_ml::bandit::LinUcbConfig;

let mut config = LinUcbConfig::default();
config.alpha = 1.0;
config.arm_count = 3;
config.feature_count = 2;
assert_eq!(config.arm_count, 3);

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.

alpha: f64

Exploration parameter alpha. Controls the exploration/exploitation trade-off. Higher values favor exploration. Must be finite and positive.

The original paper suggests alpha = 1.0 as a reasonable default.

arm_count: usize

Number of arms (actions). Must be greater than zero.

feature_count: usize

Number of features in the context vector. Must be greater than zero.

Implementations
