Abstract

Early and accurate classification of skin diseases is critical given the high global prevalence WHO estimates nearly 900 million cases worldwide, with dermatitis as the most common and the uneven distribution of dermatological expertise. EfficientNet-B3 within a Convolutional Neural Network (CNN) framework was therefore investigated for multiclass classification of skin disease images. A secondary dataset of 5,000 JPG images sourced from two public Kaggle repositories and comprising five categories (eczema, malignant, melanoma, psoriasis, and seborrheic dermatitis) was preprocessed (resized to 256×256 pixels, normalized, and augmented via rotation, flip, and zoom). Three train-validation-test splits (70:15:15, 60:20:20, and 80:10:10) were evaluated under identical training conditions using sparse categorical cross-entropy loss and the Adam optimizer (learning rate 0.001) for up to 50 epochs with early stopping. Model performance was measured via accuracy, precision, recall, and F1-score on both validation and independent test sets. The 70:15:15 split yielded the most balanced results, with validation accuracy of 93.05% and test accuracy of 91.60% (precision, recall, and F1-score all 91.60%). Although the 80:10:10 split achieved the highest test accuracy (92.00%), its smaller test set introduced potential bias. Confusion matrix analysis highlighted robust inter-class classification with minor confusion among visually similar conditions. Overall, the EfficientNet-B3–based CNN demonstrated reliable feature extraction and consistent classification across five skin disease categories, supporting its potential as a decision-support tool in dermatological practice.
