|
|
|
|
## Current Status (Live)
|
|
|
|
```bash
|
|
# Check real-time status
|
|
/home/jgrusewski/Work/foxhunt/scripts/monitor_tuning.sh
|
|
|
|
# Or with auto-refresh (every 30 seconds)
|
|
watch -n 30 /home/jgrusewski/Work/foxhunt/scripts/monitor_tuning.sh
|
|
```
|
|
|
|
**Current Progress**: DQN tuning running (Trial 12/50, 24% complete)
|
|
**ETA**: 19:25 CEST (2025-10-14)
|
|
|
|

|
|
|
|
## Quick Commands
|
|
|
|
### Monitor DQN Progress
|
|
```bash
|
|
# Tail log (live updates)
|
|
tail -f /tmp/tuning_run.log
|
|
|
|
# Count completed trials
|
|
grep -c "Trial .* completed" /tmp/tuning_run.log
|
|
|
|
# Check process status
|
|
ps aux | grep 3911478
|
|
|
|
# GPU utilization
|
|
nvidia-smi
|
|
```
|
|
|
|
### Launch Next Model (PPO)
|
|
```bash
|
|
# Manual launch (after DQN completes)
|
|
/home/jgrusewski/Work/foxhunt/target/release/examples/tune_hyperparameters \
|
|
--model PPO \
|
|
--num-trials 50 \
|
|
--epochs-per-trial 50 \
|
|
--data-dir test_data/real/databento/ml_training \
|
|
--output results/ppo_tuning_50trials.json \
|
|
> /tmp/ppo_tuning_run.log 2>&1 &
|
|
|
|
echo $! > /tmp/ppo_tuning.pid
|
|
|
|
# Automatic launch (waits for DQN, then starts PPO)
|
|
nohup /home/jgrusewski/Work/foxhunt/scripts/auto_launch_ppo.sh > /tmp/auto_launch_ppo.log 2>&1 &
|
|
```
|
|
|
|
### Sequential Tuning (All Models)
|
|
```bash
|
|
# Launch all 5 models sequentially (12-14 hours total)
|
|
nohup /home/jgrusewski/Work/foxhunt/scripts/sequential_tuning_launcher.sh \
|
|
> /tmp/sequential_tuning.log 2>&1 &
|
|
```
|
|

|
|
|
|
## Results Location
|
|
|
|
After tuning completes, results will be in:
|
|
```
|
|
/home/jgrusewski/Work/foxhunt/results/
|
|
├── dqn_tuning_50trials.json # DQN best hyperparameters
|
|
├── ppo_tuning_50trials.json # PPO best hyperparameters
|
|
├── tft_tuning_50trials.json # TFT best hyperparameters
|
|
├── mamba2_tuning_50trials.json # MAMBA-2 best hyperparameters
|
|
└── liquid_tuning_50trials.json # Liquid best hyperparameters
|
|
```
|
|
|
|
---
|
|
|
|
## Extract Best Hyperparameters
|
|
|
|
```bash
|
|
# View best trial for DQN
|
|
jq '.best_trial' results/dqn_tuning_50trials.json
|
|
|
|
# Extract best learning rate
|
|
jq '.best_trial.config.learning_rate' results/dqn_tuning_50trials.json
|
|
|
|
# Sort all trials by Sharpe ratio
|
|
jq '.all_results | sort_by(.sharpe_ratio) | reverse | .[0:5]' results/dqn_tuning_50trials.json
|
|
```
|
|
|
|

|
|
|
|
## Troubleshooting
|
|
|
|
### Process Died or Stopped
|
|
```bash
|
|
# Check if process is running
|
|
ps aux | grep tune_hyperparameters
|
|
|
|
# Restart from checkpoint (if supported)
|
|
# Note: Current implementation doesn't support checkpointing
|
|
# Need to restart from scratch
|
|
```
|
|
|
|
### GPU Out of Memory (OOM)
|
|
```bash
|
|
# Reduce batch size for TFT/MAMBA-2
|
|
# Edit tuning_config.yaml or use command line:
|
|
|
|
/home/jgrusewski/Work/foxhunt/target/release/examples/tune_hyperparameters \
|
|
--model TFT \
|
|
--num-trials 50 \
|
|
--epochs-per-trial 50 \
|
|
--batch-size 16 # Reduced from 32
|
|
```
|
|
|
|
### Identical Sharpe Ratios (All trials = 2.00)
|
|
```bash
|
|
# This is currently observed for DQN
|
|
# Investigation needed after completion
|
|
|
|
# Possible causes:
|
|
# 1. Deterministic random seed
|
|
# 2. Evaluation metric not sensitive to hyperparameters
|
|
# 3. Model already well-tuned at default settings
|
|
|
|
# Check if different hyperparameters are being tested:
|
|
grep "learning_rate\|batch_size" /tmp/tuning_run.log | head -20
|
|
```
|

### PPO
|
|
- **Trials**: 50
|
|
- **Duration**: 3-4 hours
|
|

|
|
|
|
### TFT

|
|
## Production Training (After Tuning)
|
|
|
|
Once best hyperparameters are identified:
|
|
|
|
```bash
|
|
# 1. Update model configs with best hyperparameters
|
|
vim ml/src/trainers/dqn.rs # Update DQNHyperparameters::default()
|
|
vim ml/src/trainers/ppo.rs # Update PpoHyperparameters::default()
|
|
# ... etc for other models
|
|
|
|
# 2. Run production training (4-6 weeks)
|
|
cargo run -p ml --example retrain_all_models --release --features cuda
|
|
|
|
# 3. Validate models
|
|
cargo run -p ml --example comprehensive_model_backtest --release
|
|
```
