Skin lesion classification based on dermoscopic images is an important approach to support the early detection of skin cancer. However, imbalanced data often becomes a major challenge in multi-class classification, as it can degrade model performance, particularly in recognizing minority classes. This study aims to analyze the effect of data balancing techniques on the performance of a Transformer-based skin lesion classification model using the HAM10000 dataset, which consists of seven skin lesion classes. The model employed is the Swin Transformer with four training scenarios: (1) without any balancing technique, (2) using data augmentation, (3) using class weights, and (4) a combination of data augmentation and class weights.The experimental results show that the model using the combined balancing technique of data augmentation and class weights achieves the best and most balanced performance across evaluation metrics, with an accuracy of 88.77%, precision of 83.28%, sensitivity of 83.42%, specificity of 97.07%, F1-score of 83.10%, and an AUC value of 99.04%. These results indicate that the combination of data variation and penalty through weighting enables the Swin Transformer model to learn the data effectively while minimizing errors compared to training without balancing, with data augmentation only, or with class weights only. Furthermore, this study demonstrates that the choice of data balancing techniques significantly affects model performance, especially for multi-class imbalanced datasets such as HAM10000.
