Section: Next Priorities

Replace Priority 1 (GPU Benchmark) with Model Validation:

### Priority 1: Validate Trained Models (IMMEDIATE - 1-2 hours)

**READY FOR BACKTESTING** ⚡

**Models Available**:
1. **DQN**: `ml/trained_models/production/dqn_real_data/dqn_final_epoch500.safetensors`
   - 51 checkpoints, GPU-accelerated (2.9x speedup)
   - 99.3% loss reduction (0.1 → 0.006793)
   - Training time: 17.4 seconds (500 epochs)

2. **PPO**: `ml/trained_models/production/ppo_checkpoint_epoch_500.safetensors`
   - 200 checkpoints, CPU-trained
   - 100% policy update rate, zero NaN
   - Training time: 5.6 minutes (500 epochs)

**Backtest Commands**:
```bash
# DQN validation
cargo run -p backtesting_service --example backtest_dqn -- \
  --model ml/trained_models/production/dqn_real_data/dqn_final_epoch500.safetensors \
  --data test_data/real/databento/ml_training/6E.FUT_ohlcv-1m_2024-01-*.dbn

# PPO validation
cargo run -p backtesting_service --example backtest_ppo -- \
  --model ml/trained_models/production/ppo_checkpoint_epoch_500.safetensors \
  --data test_data/real/databento/ml_training/6E.FUT_ohlcv-1m_2024-01-*.dbn

Success Criteria:

• Sharpe ratio > 1.0
• Max drawdown < 20%
• Win rate > 50%

Next Action: Backtest DQN and PPO, then deploy to production or continue MAMBA-2/TFT fixes

## Section: Next Priorities

**Update Priority 2 (ML Model Training) Status**:

```markdown
### Priority 2: Complete ML Model Training (1-2 weeks)

**Immediate (After model validation)**:

1. **MAMBA-2 Device Mismatch Fix** (4-6 hours):
   - **Issue**: Nested modules have tensors on CPU, model on CUDA
   - **Fix**: Add `.to_device(&device)` to 20-30 locations in `ml/src/mamba/`
   - **Files**: `mod.rs`, `ssd_layer.rs`, `selective_state.rs`, `hardware_optimizer.rs`
   - **Priority**: MEDIUM
   - **Testing**:
     ```bash
     cargo run -p ml --example train_mamba2 --release --features cuda -- \
       --epochs 500 --batch-size 8 --seq-len 128
     ```

2. **TFT Training Strategy Decision** (0-12 hours):
   - **Issue**: Missing CUDA layer-norm implementation in candle-core
   - **Options**:
     - A. CPU training (0 hours, 10x slower but immediate)
     - B. Upgrade candle-core (2-4 hours, risky but best performance)
     - C. Custom CUDA kernel (8-12 hours, maintenance burden)
     - D. Wait for upstream (1-2 weeks, best long-term)
   - **Recommendation**: Option A (CPU) for immediate, Option D (wait) for production
   - **Priority**: LOW
   - **Testing**:
     ```bash
     cargo run -p ml --example train_tft --release -- \
       --epochs 500 --batch-size 32  # CPU only (no --features cuda)
     ```

3. **Hyperparameter Optimization** (2-3 days):
   - Test DQN and PPO with Agent 49 optimization scripts
   - Expected improvement: 5-15% performance gain
   - Use Optuna integration via `tli tune` commands

**Status Summary**:
- ✅ **DQN**: 100% complete, GPU-accelerated, 51 checkpoints
- ✅ **PPO**: 100% complete, CPU-trained, 200 checkpoints
- ⚠️ **MAMBA-2**: Blocked, 4-6 hour fix (device mismatch)
- ⚠️ **TFT**: Blocked, 1-2 week workaround (missing CUDA kernels)

Section: GPU/CUDA Configuration

Update GPU Training Status:

### GPU/CUDA Configuration

**RTX 3050 Ti** - CUDA enabled for ML training (2-3x faster):

```bash
# Environment (already in ~/.bashrc)
export CUDA_HOME=/usr/local/cuda
export LD_LIBRARY_PATH=$CUDA_HOME/lib64:$LD_LIBRARY_PATH
export PATH=$CUDA_HOME/bin:$PATH

# Verify
nvidia-smi  # RTX 3050 Ti, CUDA 13.0, Driver 580.65.06
nvcc --version

# Usage in code (automatic device selection)
let device = Device::cuda_if_available(0)?;  // Auto-fallback to CPU

GPU Training Performance (Wave 160 Phase 3 Validated):

• DQN: 2.9x speedup (17.4s GPU vs ~50s CPU for 500 epochs)
• GPU Utilization: 39-41% sustained during training
• VRAM Usage: 135 MiB (3.3% of 4GB) for DQN
• Temperature: 55-59°C (within safe range)

Known Limitations:

• MAMBA-2: Device mismatch error (tensors on CPU, model on CUDA) - 4-6h fix
• TFT: Missing CUDA layer-norm in candle-core (rev 671de1db) - 1-2 week workaround
• PPO: No GPU implementation in candle (CPU only, 5.6 min for 500 epochs)

Workarounds:

• MAMBA-2: Add .to_device(&device) to nested modules (Agent 70 documented)
• TFT: CPU training acceptable (Option A) or wait for candle-core upgrade (Option D)
• PPO: CPU performance sufficient for current needs
