- **Number of Trials**: ${NUM_TRIALS}
|
||
- **Max Epochs per Trial**: ${MAX_EPOCHS_PER_TRIAL}
|

- **Early Stopping**: Enabled (epoch 50)

- **Validation Symbols**: ${SYMBOLS[*]}

## Search Space
|

| Hyperparameter | Search Space | Type |
|
||
|----------------|--------------|------|
|
||
| Learning Rate | [0.0001, 0.0003, 0.001] | Categorical |
|
||
| Batch Size | [32, 64, 128, 256] | Categorical |
|
||
| Gamma | [0.95, 0.99] | Categorical |
|

| GAE Lambda | [0.9, 0.95, 0.98] | Categorical |
|
||
| Clip Epsilon | [0.1, 0.2, 0.3] | Categorical |
|
||
| Entropy Coefficient | [0.001, 0.01, 0.1] | Categorical |
|
||
|
||
**Total Combinations**: 648 (intelligent sampling via TPE)
|
||
|
||
## Objective Function
|
||
|
||
\`\`\`
|
||
Combined Objective = 0.7 × Sharpe Ratio + 0.3 × Explained Variance
|
||
\`\`\`
|
||
|
||
### Rationale
|
||
- **Sharpe Ratio (70%)**: Primary metric for risk-adjusted returns
|
||
- **Explained Variance (30%)**: Critical for PPO value network accuracy
|
||
|
||
## Baseline Performance
|
||
|
||
- **Source**: Agent 79 checkpoint analysis
|
||
- **Checkpoint**: Epoch 380
|
||
- **Explained Variance**: 0.4469
|
||
- **Distance from Optimal (0.5)**: 0.0531
|
||
- **Status**: EXCELLENT (within 5% of theoretical optimal)
|
||
|
||
## Best Hyperparameters
|
||
|
||
\`\`\`
|
||
$(cat "${OUTPUT_DIR}/best_hyperparameters.txt" 2>/dev/null || echo "Not available - check tuning job status")
|
||
\`\`\`
|
||
|
||
## Value Network Convergence Analysis
|
||
|
||
### Focus Areas
|
||
1. **Explained Variance Trajectory**: Monitor convergence across trials
|
||
2. **Policy Stability**: Ensure KL divergence remains healthy
|
||
3. **Loss Dynamics**: Track policy loss and value loss evolution
|
||
4. **Entropy Decay**: Verify exploration-exploitation balance
|
||
|
||
### Expected Improvements
|
||
- Target: >5% improvement in combined objective over baseline
|
||
- Explained variance: Approach 0.47+ (vs 0.4469 baseline)
|
||
- Sharpe ratio: Measure risk-adjusted performance across all symbols
|
||
|
||
## Next Steps
|
||
|
||
1. **Validation**: Run comprehensive backtest with best hyperparameters
|
||
2. **Cross-symbol Analysis**: Compare performance across 6E, ZN, ES, NQ
|
||
3. **Production Training**: Execute 500-epoch training with optimized hyperparameters
|
||
4. **Checkpoint Analysis**: Identify optimal checkpoint (may not be final epoch)
|
||
|
||
