Abstract :
Automated melanoma detection using deep learning has reached dermatologist-level accuracy on benchmark
datasets, yet its clinical deployment remains constrained by a well-documented weakness: performance degrades sharply on
darker skin tones because public dermoscopic archives are dominated by lighter-skinned patients. This paper presents a
bias-aware, explainable framework for melanoma classification that treats data quality, subgroup fairness, and
interpretability as first-class design objectives rather than post-hoc checks. Dermoscopic images drawn from the ISIC
archive and the Diverse Dermatology Images (DDI) dataset are first cleaned using perceptual-hash-based duplicate removal
and DullRazor-based hair/artifact suppression, then passed through a ResNet50 backbone fine-tuned via transfer learning
for binary melanoma-versus-benign classification.
