Model Architecture

7 Model Types (35 total models)

Model	Pre-training	Parameters	Count
EfficientNet-B4	ImageNet → HAM10000	~19M	× 5 folds
EfficientNet-B7	ImageNet	~66M	× 5 folds
Vision Transformer (ViT)	ImageNet	~86M	× 5 folds
Swin Transformer	ImageNet	~88M	× 5 folds
Binary: ADM vs Nevus	-	~19M	× 5 folds
Binary: Nevus vs Melanoma	-	~19M	× 5 folds
Binary: Solar vs Ephelis	-	~19M	× 5 folds

Ensemble Strategy

Stage 1: Base Ensemble (20 models)

Average softmax probabilities from all base models

Stage 2: Binary Refinement (15 models) - Optional

Apply binary classifiers to refine confusing pairs:
- ADM ↔ Nevus
- Nevus ↔ Melanoma
- Solar Lentigo ↔ Ephelis

Usage

Limitations and Intended Use

Intended Use

Research and educational purposes
Dermatology AI research
Clinical decision support (with physician oversight)

Limitations

Not for clinical diagnosis: This model is intended as a decision support tool and should not replace professional medical diagnosis
Dataset bias: Trained primarily on Japanese patient data; performance may vary on other populations

Out-of-Scope Use

Autonomous clinical diagnosis without physician review
Use on non-dermatoscopic images
Commercial deployment without proper validation
