# Quick Start: ML Model Training
**Time to Complete**: 30-60 minutes (initial setup) + 4-6 weeks (training)
**Prerequisites**: Docker, RTX 3050 Ti GPU, 16GB RAM
**Goal**: Train your first ML model (DQN) with real market data
---
## Step 1: Environment Setup (5 minutes)
### Start Infrastructure
```bash
cd /home/jgrusewski/Work/foxhunt
docker-compose up -d
```
### Verify Services
```bash
docker-compose ps
# Should show: postgres, redis, vault, prometheus, grafana all healthy
```
### Run Database Migrations
```bash
cargo sqlx migrate run
```
---
## Step 2: GPU Validation (2 minutes)
### Check GPU
```bash
nvidia-smi
# Should show: RTX 3050 Ti, 4GB VRAM available
```
### Verify CUDA
```bash
nvcc --version
# Should show: CUDA 11.8 or higher
```
---
## Step 3: Run GPU Benchmark (30-60 minutes)
**Purpose**: Determine if local training (4-6 weeks) or cloud GPU ($250/week) is optimal
```bash
cargo run -p ml --example gpu_training_benchmark --release
```
**Output**: JSON report with recommendation
- `local_gpu`: Train on RTX 3050 Ti (4-6 weeks)
- `cloud_gpu`: Rent A100 GPU (1-2 weeks, $250/week)
- `either`: User choice based on cost analysis
---
## Step 4: Download Market Data (10 minutes)
### Option A: Use Existing Test Data (Quick Start)
```bash
ls test_data/
# Available: ES.FUT (1,674 bars), ZN.FUT (28,935 bars), 6E.FUT (29,937 bars)
```
### Option B: Download 90-Day Data (Recommended for Production)
```bash
# Cost: ~$2, Size: ~180,000 bars
# Symbols: ES.FUT, NQ.FUT, ZN.FUT, 6E.FUT
# Follow: /home/jgrusewski/Work/foxhunt/90_DAY_DATA_EXPANSION_PLAN.md
```
---
## Step 5: Train Your First Model (DQN)

# Epoch 1/100: Loss 0.5234, Reward 120.5, ETA 4h 23m
# Epoch 2/100: Loss 0.4891, Reward 135.2, ETA 4h 18m
# ...
```
### Expected Timeline (RTX 3050 Ti)
- **Epoch Duration**: ~2-5 minutes per epoch
- **100 Epochs**: 3-8 hours (depends on batch size)
- **Full Training**: 2-3 days for optimal convergence
---
## Step 6: Checkpoint Analysis
### List Checkpoints
```bash
tli checkpoints list --model DQN
```
### Quick Analysis
```bash
cargo run -p ml --example quick_checkpoint_analysis --release
```
### Deep Dive Analysis
```bash
cargo run -p ml --example analyze_dqn_checkpoints --release
```
**Output**:
- Top 10 checkpoints ranked by Sharpe ratio
- Explained variance trajectory
- Convergence analysis
---
## Step 7: Select Best Checkpoint
### Use Framework
```bash
# See: /home/jgrusewski/Work/foxhunt/docs/CHECKPOINT_SELECTION_FRAMEWORK.md
# Criteria:
# 1. Sharpe Ratio > 1.5 (risk-adjusted returns)
# 2. Win Rate > 55% (prediction accuracy)
# 3. Max Drawdown < 15% (risk control)
# 4. Explained Variance > 0.7 (model fit)
```
### Load Best Checkpoint
```bash
tli checkpoints load --checkpoint-id <best-checkpoint-uuid>
```
---
## Step 8: Backtest Strategy
### Run Backtest
```bash
tli backtest run \
--strategy dqn_strategy \
--symbol ES.FUT \
--start 2024-01-01 \
--end 2024-12-31 \
--checkpoint-id <best-checkpoint-uuid>
```
### Review Results
```bash
tli backtest results --backtest-id <uuid>
# Expected Output:
# Sharpe Ratio: 1.85
# Win Rate: 58.3%
# Max Drawdown: 12.4%
# Total PnL: $125,450
# Number of Trades: 1,247
```
---
## Step 9: Paper Trading (Safe Live Testing)
### Deploy Paper Trading
```bash
# See: /home/jgrusewski/Work/foxhunt/PAPER_TRADING_DEPLOYMENT_PLAN.md
# 1. Configure paper trading account
# 2. Deploy DQN model with best checkpoint
# 3. Monitor for 2-4 weeks
# 4. Validate Sharpe ratio > 1.5 in live conditions
```
---
## Step 10: Production Deployment
### Prerequisites
- ✅ Paper trading validated (2-4 weeks)
- ✅ Sharpe ratio > 1.5 in live conditions
- ✅ Max drawdown < 15%
- ✅ Risk limits configured
- ✅ Security audit complete
### Deploy to Production
```bash
# See: /home/jgrusewski/Work/foxhunt/docs/PRODUCTION_DEPLOYMENT_RUNBOOK_V3.md
# 1. Blue-green deployment
# 2. Canary release (1% traffic)
# 3. Monitor for 48 hours
# 4. Gradual rollout to 100%
```
---
## Troubleshooting
### GPU Out of Memory
```bash
# Reduce batch size in training config
# Default: 64 → Try: 32 or 16
```
### Training Too Slow
```bash
# Check GPU utilization
nvidia-smi -l 1
# If <80% utilization: Increase batch size
# If >95% utilization: Optimal (expected)
```
### Checkpoint Not Found
```bash
# List all checkpoints
tli checkpoints list --model DQN
# Verify checkpoint directory
ls -lh ~/.foxhunt/checkpoints/DQN/
```
### Poor Backtest Results (Sharpe < 1.0)
```bash
# Options:
# 1. Train longer (200-500 epochs)
# 2. Hyperparameter tuning (see tuning guide)
# 3. Try different model (PPO, MAMBA-2)
# 4. Add more training data (90 days recommended)
```
---
## Next Steps
### Train Additional Models
```bash
# PPO (2-3 days)
tli train start --model PPO --symbol ES.FUT --epochs 100
# MAMBA-2 (3-4 days, requires more VRAM)
tli train start --model MAMBA2 --symbol ES.FUT --epochs 100
# TFT (5-7 days, largest model)
tli train start --model TFT --symbol ES.FUT --epochs 100
```
### Hyperparameter Tuning
```bash
# Optimize DQN hyperparameters (4-8 hours, 50 trials)
tli tune start --model DQN --trials 50 --watch
# See: /home/jgrusewski/Work/foxhunt/TUNING_QUICKSTART_GUIDE.md
```
### Ensemble Models
```bash
# Combine multiple models for better performance
# See: /home/jgrusewski/Work/foxhunt/ENSEMBLE_IMPLEMENTATION_GUIDE.md
# Expected: Sharpe ratio 2.0-2.5 with ensemble (vs 1.5-2.0 single model)

# Quick Start: Hyperparameter Tuning
**Time to Complete**: 4-8 hours (50 trials)
**Prerequisites**: Trained baseline model, ML Training Service running
**Goal**: Find optimal hyperparameters for 10-20% performance improvement
---
## What is Hyperparameter Tuning?
**Problem**: Default hyperparameters are rarely optimal
- Learning rate too high → unstable training
- Batch size too small → slow convergence
- Hidden layers wrong size → underfitting/overfitting
**Solution**: Automated search (Optuna) to find best configuration
- **Objective**: Maximize Sharpe ratio (risk-adjusted returns)
- **Method**: Bayesian optimization (smart search, not brute force)
- **Time**: 5-10 minutes per trial × 50 trials = 4-8 hours
**Expected Improvement**:
- Baseline Sharpe: 1.5
- Tuned Sharpe: 1.7-2.0 (10-30% improvement)
---
## Step 1: Prerequisites (5 minutes)
### Services Running
```bash
# Check services
docker-compose ps
# Should be running:
# - postgres (Optuna study storage)
# - ml_training_service
# - api_gateway
```
### Baseline Model
```bash
# List trained models
tli checkpoints list --model DQN
# You should have at least one checkpoint
# If not, train baseline first: see QUICK_START_TRAINING.md
```
---
## Step 2: Review Tuning Configuration (2 minutes)
### Check Search Space
```bash
cat tuning_config.yaml
```
**Example DQN Configuration**:
```yaml
dqn:
learning_rate:
type: loguniform
low: 1.0e-5
high: 1.0e-2
batch_size:
type: categorical
choices: [32, 64, 128, 256]
gamma:
type: uniform
low: 0.95
high: 0.999
hidden_size:
type: categorical
choices: [128, 256, 512]
num_layers:
type: int
low: 2
high: 4
```

```
---
## Advanced Tuning Strategies
### Multi-Model Tuning
```bash
# Tune all models in parallel
tli tune start --model DQN --trials 50 &
tli tune start --model PPO --trials 50 &
tli tune start --model MAMBA2 --trials 50 &
tli tune start --model TFT --trials 50 &
# Wait for all jobs to complete (12-24 hours)
```
### Multi-Symbol Tuning
```bash
# Find hyperparameters that work across symbols
tli tune start \
--model DQN \
--trials 50 \
--symbols ES.FUT,NQ.FUT,ZN.FUT,6E.FUT
# This tests generalization across markets
```
### Warm Start (Continue Tuning)
```bash
# If tuning interrupted or want more trials
tli tune start \
--model DQN \
--trials 50 \
--study-name dqn-tuning-20251014-153045 # Reuse existing study
# Optuna will resume from last trial
```
---
## Troubleshooting
### Trial Failures
```bash
# Check logs
docker-compose logs -f ml_training_service
# Common causes:
# - OOM (reduce batch_size range in config)
# - NaN loss (reduce learning_rate upper bound)
# - Timeout (increase epochs per trial)
```
### Slow Tuning
```bash
# Speed up by reducing epochs per trial
tli tune start --model DQN --trials 50 --epochs 50
# Trade-off: Faster tuning but less accurate Sharpe estimates
```
### Poor Results (No Improvement)
```bash
# Expand search space in tuning_config.yaml
learning_rate:
low: 1.0e-6 # Was 1.0e-5
high: 5.0e-2 # Was 1.0e-2
# Try more trials
tli tune start --model DQN --trials 100 # Was 50
```
### Out of Memory
```bash
# Reduce batch_size range
batch_size:
choices: [16, 32, 64] # Was [32, 64, 128, 256]
# Or reduce hidden_size range
hidden_size:
choices: [64, 128, 256] # Was [128, 256, 512]
```
---
## Best Practices
### Trial Count
- **Quick test**: 10-20 trials (1-2 hours)
- **Standard**: 50 trials (4-8 hours)
- **Thorough**: 100 trials (8-16 hours)
- **Research**: 200+ trials (16-32 hours)
### Early Stopping
```bash
# Optuna MedianPruner automatically stops poor trials
# Saves 30-50% time by killing obviously bad hyperparameters
# Check pruned trials
tli tune status --job-id <job-id> --show-pruned
```
### Study Persistence
```bash
# All studies saved to PostgreSQL (JournalStorage)
# Can resume anytime, even after service restart
# List all studies
tli tune list
# Resume specific study
tli tune start --study-name <study-name> --trials 50
```
---
## Next Steps
### Ensemble Tuning
```bash
# After tuning individual models, optimize ensemble weights
# See: /home/jgrusewski/Work/foxhunt/ENSEMBLE_WEIGHT_OPTIMIZATION_QUICKSTART.md
tli ensemble optimize \
--models DQN,PPO,MAMBA2,TFT \
--trials 100
```
### Production Deployment
```bash
# Deploy tuned model to paper trading
# See: /home/jgrusewski/Work/foxhunt/PAPER_TRADING_DEPLOYMENT_PLAN.md
# Expected: Sharpe > 1.8 in live conditions
```
