                                           diagnosis of any skin-related lesion/disease.
                                           There are 2 main components that address the two major problems
                                           previously explained:
                                           1.  Deep-Generative Style Transfer for Skin Tone Data Augmentation:
                                              This component addresses the racial divide in intelligent dermato-
                                              logical diagnosis. EquiDermAI uses an image-to-image translation
                                              method based on CycleGAN (Zhu et al., 2017) to perform seman-
                                              tic-preserving transformation of skin lesion images. Specifically, it
                                              adapts lesion images from overrepresented lighter skin tones to
                                              reflect underrepresented darker skin tones while preserving lesion
                                              morphology and clinical features. Unlike classical neural style transfer,
                                              which may distort structural pathology, CycleGAN operates without
                                              requiring paired training data and focuses on domain adaptation,
                                              enabling realistic generation of lesions on diverse skin tones without
                                              altering diagnostic-relevant morphology. By augmenting datasets
                                              with these clinically faithful synthetic images, EquiDermAI improves
                                              diagnostic model generalisation across skin types and helps reduce
                                              misdiagnosis rates in underrepresented populations.
                                           2.  Quantized TinyML Development for Resource-Constrained Areas:
                                              This component addresses the digital divide. With many regions in
                                              the world lacking access to powerful technological tools, it is import-
                                              ant to keep diagnostic resources very efficient. EquiDermAI further
                                              optimizes AI models for low-power devices, enabling accurate diag-
                                              nosis in resource-constrained areas with limited computing power
                                              or internet connectivity (Warden & Situnayake, 2019).
                                           These two components are intricately designed to contribute to the
                                           overall goal of creating an inclusive and accessible skin disease diagnosis
                                           system. By combining advanced deep learning techniques with efficient
                                           deployment strategies, EquiDermAI aims to overcome both racial and
                                           regional barriers in dermatological care, democratizing accurate skin
                                           disease diagnosis.
                                           CONSIDERATIONS: There are legitimate concerns regarding whether
                                           generated images retain diagnostic fidelity, particularly when transform-
                                           ing skin tone while preserving the clinical morphology of lesions. To
                                           address this, EquiDermAI will involve expert validation from board-cer-
                                           tified dermatologists and skin-of-colour specialists in future iterations.
                                           These experts will assess the realism and clinical accuracy of the synthetic
                                           images, and validation may incorporate structured annotation protocols
                                           with inter-rater reliability metrics (e.g., Cohen’s kappa) to quantify agree-
                                           ment. Alternatively, or in parallel, automated similarity assessments may
                                           be employed by comparing the learned feature embeddings of real
                                           and generated lesions using pre-trained dermatological classification
                                           networks. Techniques such as perceptual loss or cosine similarity in latent
                                           space can serve as quantitative proxies for evaluating whether lesion
                                           morphology remains preserved during style transformation. These
                                           safeguards aim to ensure that synthetic data used for training maintains
                                           clinical utility and does not introduce misleading artifacts.
