Prepare a dermoscopy dataset
Collect licensed dermoscopy or clinical images with expert labels (e.g. ISIC) and split by patient to avoid leakage; include image augmentation and quality filters.
Detect skin lesions. Prioritise clinically-relevant metrics.
Skin cancer detection models classify images of skin lesions as benign or malignant and must be evaluated using sensitivity, specificity, AUC and calibration. Image quality, class imbalance, annotation noise and population differences are common failure modes.

Skin cancer detection models classify images of skin lesions as benign or malignant and must be evaluated using sensitivity, specificity, AUC and calibration. Image quality, class imbalance, annotation noise and population differences are common failure modes.
A proposed application is a triage tool for dermatology clinics that highlights suspect lesions for clinician review; a human reviewer stays in charge and the system must not be used for real clinical decisions.
Collect licensed dermoscopy or clinical images with expert labels (e.g. ISIC) and split by patient to avoid leakage; include image augmentation and quality filters.
Fine-tune a pretrained convolutional network (transfer learning) and standardise input sizes, augmentation and class-weighting for imbalance.
Report sensitivity, specificity, AUC and calibration; inspect high-confidence false negatives and subgroup performance by skin tone and device.
Provide probability thresholds, a clinician review UI, audit logging and monitoring for data drift and image-quality issues.
The supplied starter creates a synthetic tabular classification dataset with sklearn.make_classification, builds a Pipeline that scales features and fits a RandomForestClassifier, then prints a classification report on a held-out test split. It does not load or process skin images, nor does it use image models or medical datasets.
model = Pipeline(
steps=[
("scale", StandardScaler()),
("classifier", RandomForestClassifier(n_estimators=250, random_state=RANDOM_STATE)),
]
)
model.fit(X_train, y_train)The starter uses synthetic numeric features (make_classification) rather than dermoscopy or clinical images, so it cannot validate any image-based skin cancer method. The pipeline demonstrates basic modelling steps but omits image I/O, CNN architectures, transfer learning, clinical metrics handling, calibration and regulatory considerations required for healthcare use.
Proposed extension: fine-tune a pretrained CNN on a labelled dermoscopy dataset to produce calibrated malignancy probabilities and surface a clinician-review interface for triage.
This is a potential application pathway, not a delivered product. The supplied starter does not implement this service or validate it with real users.
