Struct MixtureSyntheticUser 

pub struct MixtureSyntheticUser {
    pub thetas: Vec<Vec<f64>>,
}

A simulated user whose taste has several islands: true utility is the max over component tastes (“I love a great drone OR a great pluck”). A single linear θ provably cannot represent this — it is the ground truth for the K > 1 mixture gate.

Fields

thetas: Vec<Vec<f64>>

Component ground-truth weight vectors.

Implementations

impl MixtureSyntheticUser

pub fn utility(&self, phi: &[f64]) -> f64

True utility: best component’s score.

pub fn duel<R: Rng>(&self, rng: &mut R, a: &[f64], b: &[f64]) -> bool

Sample a duel outcome (true = chose A), Bradley–Terry noise on the max-utility.

pub fn observe_duel<R: Rng>( &self, rng: &mut R, a: Vec<f64>, b: Vec<f64>, session: usize, ) -> Observation

Generate a full duel observation on the given pair.
