|
===============
|
|
|
|
TO USE TRAINED ML MODELS NOW:
|
|
1. Implement model_loader.rs (checkpoint loading)
|
|
2. Connect to MLStrategyEngine
|
|
3. Test with trained MAMBA-2 checkpoint
|
|
Estimated: 1-2 weeks
|
|
|
|
TO IMPROVE PERFORMANCE:
|
|
1. Add batch prediction support (10-100x speedup)
|
|
2. GPU acceleration for inference
|
|
3. Memory optimization for equity curves
|
|
Estimated: 1-2 weeks
|
|
|
|
TO COMPLETE INTEGRATION:
|
|
1. Finish RED-GREEN-REFACTOR for 4 failing tests
|
|
2. Add confidence threshold calibration
|
|
3. Add edge case testing (gaps, spikes)
|
|
Estimated: 1-2 weeks
|
|
|

CONCLUSION
|
|
==========
|
|
|
|
Status: FRAMEWORK PRODUCTION-READY FOR RULE-BASED STRATEGIES
|
|
ML FRAMEWORK READY PENDING CHECKPOINT LOADING
|
|
|
|
Backtesting service has excellent ML integration framework with comprehensive
|
|
feature extraction, performance metrics, and ensemble prediction capabilities.
|
|
|
|
The architecture is well-designed and ready to accept trained ML models.
|
|
However, checkpoint loading is not implemented, preventing use of trained
|
|
MAMBA-2/DQN/PPO/TFT models.
|
|
|
|
With 1-2 weeks of implementation work, backtesting will be able to:
|
|
- Load trained model checkpoints from S3/local storage
|
|
- Run ensemble predictions with multiple models
|
|
- Compare ML strategies against rule-based benchmarks
|
|
- Generate comprehensive performance reports
|
|
- Support batch prediction optimization
|
|
|
|
Current capability: 83% ready (20/24 tests passing)
|
|
Final capability with implementation: 100% ready for production ML backtesting
