## 🔧 Configuración de Token HuggingFace
|
| 751 |
+
|
| 752 |
+
Para usar Google Derm Foundation, configura tu token:
|
| 753 |
+
|
| 754 |
+
```bash
|
| 755 |
+
export HUGGINGFACE_TOKEN="tu_token_aqui"
|
| 756 |
+
```
|
| 757 |
+
|
| 758 |
+
O en Python:
|
| 759 |
+
```python
|
| 760 |
+
import os
|
| 761 |
+
os.environ['HUGGINGFACE_TOKEN'] = 'tu_token_aqui'
|
| 762 |

+
## 📚 Modelos Soportados
|
| 765 |
+
|
| 766 |
+
El sistema puede cargar automáticamente diversos tipos de modelos:
|
| 767 |
+
- **ViT (Vision Transformer)**: Modelos transformer para imágenes
|
| 768 |
+
- **Swin Transformer**: Arquitectura jerárquica avanzada
|
| 769 |
+
- **EfficientNet**: Redes eficientes y escalables
|
| 770 |
+
- **Foundation Models**: Modelos base pre-entrenados
|
| 771 |
+
|
| 772 |
+
## 🎯 Métricas del Sistema
|
| 773 |
+
|
| 774 |
+
- **Consenso de Malignidad**: Porcentaje de modelos que predicen malignidad
|
| 775 |
+
- **Acuerdo Ponderado**: Concordancia entre modelos con pesos dinámicos
|
| 776 |
+
- **Score de Riesgo**: Puntuación combinada 0-1 basada en múltiples factores
|
| 777 |
+
- **Varianza de Predicción**: Medida de incertidumbre del ensemble

| 806 |
+
|
| 807 |
+
Los pesos se asignan automáticamente según:
|
| 808 |
+
- Tipo de modelo (foundation > swin > efficientnet > vit)
|
| 809 |
+
- Confianza de la predicción
|
| 810 |
+
- Histórico de rendimiento
