# PPO Hyperparameter Tuning - Quick Start
|
||
|
||
**Duration**: 8-12 hours | **Trials**: 50 | **Objective**: 0.7 × Sharpe + 0.3 × ExplainedVar
|
||
|
||
---
|
||
|
||
## One-Line Execution
|
||
|
||
```bash
|
||
cd /home/jgrusewski/Work/foxhunt && ./run_ppo_comprehensive_tuning.sh
|
||
```
|
||
|
||
That's it! The script handles everything.
|
||

|
||
|
||
## What Gets Optimized
|
||
|
||
| Hyperparameter | Choices | Current Best (Epoch 380) |
|
||
|----------------|---------|--------------------------|
|
||
| Learning Rate | [0.0001, 0.0003, 0.001] | 1e-4 |
|
||
| Batch Size | [32, 64, 128, 256] | 64 |
|
||
| Gamma | [0.95, 0.99] | 0.99 |
|
||
| GAE Lambda | [0.9, 0.95, 0.98] | 0.95 |
|
||
| Clip Epsilon | [0.1, 0.2, 0.3] | 0.2 |
|
||
| Entropy Coef | [0.001, 0.01, 0.1] | 0.05 |
|
||
|
||
**Search Space**: 648 combinations → 50 intelligent trials (TPE sampling)

## Monitoring Progress
|
||
|
||
### Real-Time Monitoring
|
||
|
||
```bash
|
||
# Progress bar with ETA
|
||
./run_ppo_comprehensive_tuning.sh
|
||
# (automatically monitors progress)
|
||
```
|
||
|
||
### Manual Status Check
|
||
|
||
```bash
|
||
# Get job ID from job_id.txt
|
||
export JOB_ID=$(cat ml/trained_models/tuning/ppo_comprehensive/job_id.txt)
|
||
|
||
# Check status
|
||
cargo run -p tli -- tune status --job-id $JOB_ID
|
||
```
|
||
|
||

|
||
|
||
## Results Location
|
||
|
||
After completion (8-12 hours):
|
||
|
||
```
|
||
ml/trained_models/tuning/ppo_comprehensive/
|
||
├── best_hyperparameters.txt ← USE THIS FOR PRODUCTION
|
||
├── TUNING_SUMMARY_REPORT.md ← SHARE WITH TEAM
|
||
└── tuning_execution.log ← DEBUG IF NEEDED
|
||
```
|
||

|
||
|
||
## Success Criteria
|
||
|
||
✅ **Target**: 5-10% improvement over baseline
|
||
✅ **Baseline**: Epoch 380 (explained_var=0.4469, EXCELLENT)
|
||
✅ **Expected**: Sharpe > 1.5, ExplainedVar > 0.45

|
||
|
||
## After Tuning
|
||
|
||
### Step 1: Production Training (6-8 hours)
|
||
|
||
```bash
|
||
# Use best hyperparameters for 500-epoch training
|
||
cargo run -p ml --example train_ppo_production \
|
||
--config best_hyperparameters.txt \
|
||
--epochs 500
|
||
```
|
||
|
||
### Step 2: Checkpoint Analysis
|
||
|
||
```bash
|
||
# Find optimal checkpoint (may not be epoch 500)
|
||
cargo run -p ml --example analyze_ppo_checkpoints \
|
||
--checkpoint-dir ml/trained_models/production/ppo_tuned/
|
||
```
|
||
|
||
### Step 3: Backtesting
|
||
|
||
```bash
|
||
# Test on all 4 symbols
|
||
cargo run -p backtesting_service --example comprehensive_backtest \
|
||
--model ppo_tuned/ppo_final_epoch500.safetensors \
|
||
--symbols 6E.FUT,ZN.FUT,ES.FUT,NQ.FUT
|
||
```

||
## Troubleshooting
|
||
|
||
| Issue | Fix |
|
||
|-------|-----|
|
||
| GPU OOM | Auto-handled (batch size <= 230) |
|
||
| Service down | `cargo run -p ml_training_service --release &` |
|
||
| Missing data | Check `test_data/*.dbn.zst` files |
|
||
| Slow progress | Check `nvidia-smi` (GPU utilization) |
