Struct DiverseBeamConfig 

pub struct DiverseBeamConfig {
    pub beam_width: usize,
    pub n_groups: usize,
    pub max_steps: usize,
    pub vocab_size: usize,
    pub eos_id: usize,
    pub diversity_strength: f32,
    pub length_norm_alpha: f32,
}

Configuration for Diverse Beam Search (Vijayakumar et al. 2018).

Fields

beam_width: usize

Total beam width B. Must be divisible by n_groups.

n_groups: usize

G: number of diversity groups. Each group gets beam_width / n_groups beams.

max_steps: usize

Maximum decoding steps.

vocab_size: usize

Vocabulary size (number of tokens).

eos_id: usize

Token ID for end-of-sequence.

diversity_strength: f32

λ: Hamming diversity penalty strength.

length_norm_alpha: f32

GNMT-style length normalisation exponent. 0.0 = no normalisation.
