Agent G9: TFT 225-Feature Update - Quick Reference
Status: ✅ COMPLETE
Date: 2025-10-18
What Changed
1. Training Script (ml/examples/train_tft_dbn.rs)
- ✅ Added
FeatureConfig::wave_d()initialization - ✅ Updated
convert_to_tft_data()to accept feature config - ✅ Changed historical features from 50 → 225 per timestep
- ✅ Updated array shape:
(lookback_window, 50)→(lookback_window, 225) - ✅ Added Wave D features (indices 201-224, 24 features)
2. Trainer Config (ml/src/trainers/tft.rs)
- ✅ Updated
num_unknown_features: 50→225 - ✅ Updated checkpoint naming:
tft_epoch_{}→tft_225_epoch_{}
Feature Breakdown (225 Total)
| Range | Category | Count | Description |
|---|---|---|---|
| 0-200 | Wave C | 201 | OHLCV, technicals, microstructure, statistical |
| 201-210 | CUSUM | 10 | Structural break detection |
| 211-215 | ADX | 5 | Directional indicators |
| 216-220 | Transitions | 5 | Regime transition probabilities |
| 221-224 | Adaptive | 4 | Position sizing, stop-loss, Sharpe |

Validation Checklist
- ✅ Zero compilation errors
- ✅ Feature count: 225 (verified via
feature_config.feature_count()) - ✅ Historical features shape:
[60, 225] - ✅ Checkpoint naming:
tft_225_epoch_{epoch}.safetensors - ✅ Tests updated:
test_convert_to_tft_format()
Expected Output
Configuration:
• Feature count: 225 (Wave D: Wave C 201 + Wave D 24)
• Hidden dimension: 256
• Lookback window: 60
• Forecast horizon: 10

Next Steps
- Dry run:
cargo run -p ml --example train_tft_dbn --release -- --epochs 1 - Full training: 50 epochs on ES.FUT data
- Multi-symbol: Train on ES.FUT, NQ.FUT, 6E.FUT, ZN.FUT
- Replace proxies: Integrate real regime features (Agents D13-D16)
Key Metrics
- Compilation: ✅ 0 errors, 66 warnings (non-critical)
- Input dimension: 225 features (4.5x from 50)
- Expected inference: ~3.5ms (target: <5ms)
- Expected GPU memory: ~180MB training (440MB total budget)
Notes
⚠️ Wave D features (201-224) are currently proxy features derived from OHLCV. They will be replaced with actual regime detection features from Agents D13-D16 in Phase 4.
