## 🔧 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 |
+
```
|
763 |
+
|
764 |
+
## 📚 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

### Añadir Nuevos Modelos
|
785 |
+
|
786 |
+
Para añadir un nuevo modelo al sistema:
|
787 |
+
|
788 |
+
```python
|
789 |
+
MODEL_CONFIGS.append({
|
790 |
+
'name': 'Nombre del Modelo',
|
791 |
+
'id': 'huggingface/model-id',
|
792 |
+

|
793 |
+
'description': 'Descripción del modelo',
|
794 |
+
'emoji': '🤖'
|
795 |
+
})
|
796 |
+
```
|
797 |
+
|
798 |
+
### Tipos de Modelos Soportados
|
799 |
+
|
800 |
+
- **vit**: Vision Transformer
|
801 |
+
- **swin**: Swin Transformer
|
802 |
+
- **efficientnet**: EfficientNet
|
803 |
+
- **foundation**: Modelos foundation (como Google Derm)
|
804 |
+
|
805 |
+
### Pesos del Ensemble
|
806 |
+
|
807 |
+
Los pesos se asignan automáticamente según:
|
808 |
+
- Tipo de modelo (foundation > swin > efficientnet > vit)
|
809 |
+
- Confianza de la predicción
|
810 |
