Ensemble Coordinator Quick Reference
Quick Start
use ml::ensemble::coordinator_extended::{ExtendedEnsembleCoordinator, EnsembleConfig};
use ml::ModelPrediction;
// Create ensemble with default config
let config = EnsembleConfig::default();
let coordinator = ExtendedEnsembleCoordinator::new(config);
// Register all 6 models
coordinator.register_model("DQN".to_string(), 0.167).await?;
coordinator.register_model("PPO".to_string(), 0.167).await?;
coordinator.register_model("TFT".to_string(), 0.167).await?;
coordinator.register_model("MAMBA-2".to_string(), 0.167).await?;
coordinator.register_model("Liquid".to_string(), 0.167).await?;
coordinator.register_model("TLOB".to_string(), 0.165).await?;
// Get predictions from all models
let predictions = vec![
dqn.predict(&features).await?,
ppo.predict(&features).await?,
tft.predict(&features).await?,
mamba2.predict(&features).await?,
liquid.predict(&features).await?,
tlob.predict(&features).await?,
];
// Make ensemble decision
let decision = coordinator.predict(predictions).await?;
// Record outcomes for adaptive weighting
coordinator.record_outcome("DQN", return_value).await?;
// Get current state
let weights = coordinator.get_weights().await;
let diversity = coordinator.get_diversity_metrics().await;
let attribution = coordinator.get_performance_attribution().await;
Configuration
EnsembleConfig {
adaptive_weighting: true, // Enable adaptive weighting
min_correlation_threshold: 0.7, // Diversity threshold
diversity_adjustment_factor: 0.2, // Diversity weight bonus
performance_window_size: 1000, // Rolling window size
min_weight: 0.05, // 5% minimum per model
max_weight: 0.40, // 40% maximum per model
}
