Expand description

Aggregation model for converting user feedback to fitness

Variants§

§

DirectRating

Direct rating average

Simply averages all ratings received for each candidate. Uses default_rating for candidates with no ratings.

Fields

§default_rating: f64

Default rating for unevaluated candidates

§

Elo

Elo rating system

Classic chess-style rating from pairwise comparisons. Good for transitive preference modeling.

Fields

§initial_rating: f64

Initial rating for new candidates

§k_factor: f64

K-factor controlling rating volatility

§

BradleyTerry

Bradley-Terry model

Maximum likelihood estimation for pairwise comparison data. Provides more statistically principled estimates than Elo. Now supports proper MLE with Newton-Raphson or MM algorithms.

Fields

§initial_strength: f64

Initial strength parameter

§optimizer: BradleyTerryOptimizer

Optimizer configuration (Newton-Raphson or MM)

§

BradleyTerrySimple

Legacy Bradley-Terry model (for backward compatibility)

Uses the simplified iterative MM approach from earlier versions.

Fields

§initial_strength: f64

Initial strength parameter

§learning_rate: f64

Learning rate for iterative updates

§iterations: usize

Number of iterations

§

ImplicitRanking

Implicit ranking from batch selections

Assigns bonuses to selected candidates and penalties to non-selected candidates in each batch.

Fields

§selected_bonus: f64

Fitness bonus for being selected

§not_selected_penalty: f64

Fitness penalty for not being selected

§base_fitness: f64

Base fitness for all candidates
