## How to Run Extended Training
|
|
|
|
### Option 1: Agent F6 Script (Recommended)
|
|
|
|
```bash
|
|
# Fix build lock first
|
|
pkill -f cargo && sleep 2 && cargo clean
|
|
|
|
# Run 100-epoch training with tuned hyperparameters
|
|
cargo run -p ml --example train_ppo_extended --release --features cuda -- \
|
|
--epochs 100 \
|
|
--learning-rate 0.0001 \
|
|
--value-coef 1.0 \
|
|
--entropy-coef 0.05 \
|
|
--no-early-stopping
|
|
|
|
# Training time: ~15 minutes
|
|
# Output: /home/jgrusewski/Work/foxhunt/ml/trained_models/ppo_extended/
|
|
```
|
|
|
|
### Option 2: Original Script with Custom Args
|
|
|
|
```bash
|
|
cargo run -p ml --example train_ppo --release --features cuda -- \
|
|
--epochs 100 \
|
|
--learning-rate 0.0001 \
|
|
--no-early-stopping
|
|
```

## Next Steps
|
|
|
|
### Immediate (This Week)
|
|
1. **Execute 100-epoch training** (~15 min)
|
|
2. **Validate improvements** (explained variance >0.5, value loss <15.0)
|
|
3. **Document optimal hyperparameters** for 225-feature retraining
|
|
|
|
### Short-Term (1-2 Weeks)
|
|
4. **Backtest 20-epoch vs 100-epoch** (compare Sharpe, win rate)
|
|
5. **Deploy 100-epoch model to staging** (1-2 days paper trading)
|
|
|
|
### Medium-Term (4-6 Weeks) 🔴 CRITICAL
|
|
6. **Retrain with 225 features** (201 Wave C + 24 Wave D)
|
|
7. **Expected: +25-50% Sharpe improvement**
|
|
8. **Production readiness: 85-90% → 100%**

## Critical Blockers
|
|
|
|
1. **Build System Lock** 🔴
|
|
- Fix: `pkill -f cargo && sleep 2 && cargo clean`
|
|
- Time: 5 minutes
|
|
|
|
2. **16-Feature Limitation** 🔴
|
|
- Fix: Retrain with 225 features (4-6 weeks)
|
|
- Impact: +25-50% Sharpe improvement
|
|
