ET-ML-007: Hierarchical Attention Architecture
Resumen Ejecutivo
Arquitectura de ML de 3 niveles jerarquicos para mejorar la rentabilidad de modelos de prediccion de rango:
- Nivel 0 - Attention Model: Aprende CUANDO prestar atencion (sin hardcodear horarios)
- Nivel 1 - Base Models: Modelos existentes mejorados con attention_score como feature
- Nivel 2 - Metamodel: Sintetiza predicciones de 5m y 15m por activo
Problema resuelto: Modelos con 91-99% precision direccional pero R:R 2:1 NO rentable (WR=24.5%, Expectancy=-0.266)

Nuevas opciones de configuracion:
@dataclass
class TrainerConfig:
# ... opciones existentes ...
use_attention_features: bool = False
attention_model_path: str = 'models/attention'
Proceso de Generacion de Features de Atencion
- Carga el modelo de atencion entrenado
- Genera features de atencion para cada fila
- Agrega
attention_score y attention_class al dataset
- Entrena modelo base con 52 features (50 originales + 2 atencion)
Uso del Script de Entrenamiento
# Entrenar modelos base CON attention features
python scripts/train_symbol_timeframe_models.py \
--use-attention \
--attention-model-path models/attention

Hallazgos Clave V2
- Filtrar attention ALTA mejora resultados: Attention >= 2.0 tiene peor win rate
- R:R dinamico es crucial: Usar delta_high/delta_low para calcular R:R optimo
- Balance filtrado/oportunidades: "dynamic_rr" tiene mejor profit total (+17.55 R)
- Conservative mas estable: Menor drawdown (14.91 R vs 35.33 R)

Conclusiones Cross-Validation
conservative es la unica estrategia rentable en ambos activos
- EURUSD requiere filtros mas estrictos - 96.8% de trades filtrados vs 85.5% en XAUUSD
- La estrategia conservative es robusta - funciona en diferentes activos
Neural Gating Network (Arquitectura Implementada)
Se implemento una arquitectura alternativa al XGBoost Stacking:
Archivo: src/models/neural_gating_metamodel.py
Arquitectura:
alpha = sigmoid(MLP([attention_5m, attention_15m, context]))
pred_final = alpha * pred_5m + (1-alpha) * pred_15m + residual
Componentes:
- GatingNetwork: Aprende pesos dinamicos para 5m vs 15m
- ResidualNetwork: Correccion fina del promedio ponderado
- ConfidenceNetwork: Clasificador binario de senales
Estado: Codigo completo, entrenamiento pendiente de integracion con pipeline de datos.
Proximos Pasos Sugeridos
- Walk-forward optimization: Validar robustez con mas periodos OOS (2023, 2024 Q1-Q2)
- Ampliar activos: Entrenar metamodelos para BTCUSD, GBPUSD, USDJPY
- Neural Gating Training: Completar integracion de datos para entrenar version neural
- Production deployment: Integrar con FastAPI y servicios de trading
