# Ensemble Coordinator Quick Reference
|
|
|
|
## Quick Start
|
|
|
|
```rust
|
|
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
|
|
|
|
```rust
|
|
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
|
|
}
|
|
```
|
|
|
|
## Key Methods
|
|
|
|
| Method | Purpose | Returns |
|
|
|--------|---------|---------|
|
|
| `register_model(id, weight)` | Add model to ensemble | `MLResult<()>` |
|
|
| `predict(predictions)` | Make ensemble decision | `MLResult<EnsembleDecision>` |
|
|
| `record_outcome(id, return)` | Track performance | `MLResult<()>` |
|
|
| `get_weights()` | Current model weights | `HashMap<String, f64>` |
|
|
| `get_diversity_metrics()` | Correlation data | `DiversityMetrics` |
|
|
| `get_performance_attribution()` | Sharpe/win rates | `PerformanceAttribution` |
|
|
| `get_weight_history()` | Weight evolution | `Vec<WeightSnapshot>` |
|
|
| `get_correlation_heatmap()` | Pairwise correlations | `Vec<(String, String, f64)>` |
|
|
|
|
## Testing
|
|
|
|
```bash
|
|
# Run 6-model test (1000 predictions)
|
|
cargo run -p ml --example six_model_ensemble --release
|
|
|
|
# Generate visualizations
|
|
cd ensemble_viz
|
|
python3 generate_plots.py
|
|
```
|
|
|
|
## Expected Performance
|
|
|
|
- **Ensemble Sharpe**: 2.7-3.0 (17-30% improvement over best individual)
|
|
- **Win Rate**: 60% (vs 58% for DQN)
|
|
- **Latency**: <5ms per ensemble prediction
|
|
- **Diversity**: 25-35% disagreement rate
|
|
|
|
## Supported Models
|
|
|
|
1. **DQN** - Deep Q-Network (momentum-based RL)
|
|
2. **PPO** - Proximal Policy Optimization (policy gradient RL)
|
|
3. **TFT** - Temporal Fusion Transformer (attention-based)
|
|
4. **MAMBA-2** - State Space Model (SSM architecture)
|
|
5. **Liquid** - Liquid Neural Network (adaptive dynamics)
|
|
6. **TLOB** - Temporal Limit Order Book (microstructure)
