An Optimized Ensemble Model for Skin Cancer Classification Using Genetic Algorithms and Transfer Learning
摘要
Skin cancer remains one of the most common and deadly forms of cancer globally, requiring precise and effective diagnostic tools. This study introduces a novel approach for improving skin cancer detection and classification by incorporating Genetic Algorithm Optimized Ensemble (GAOE) methods with transfer learning and meta-learning techniques. We refined three well-known pre-trained models—EfficientNetB3, ResNet50, and VGG16 using the ISIC 2020 dataset. We used transfer learning, customizing them for skin cancer detection employing a weighted ensemble approach, where initial performance-based weights were calculated and optimized via evolutionary algorithms. The GAOE model, which integrates genetic algorithms and meta-learning, performed exceptional performance accuracy of 99.43%. The GAOE model also surpassed the weighted ensemble in precision 98%, recall 99%, and F-score 99%. Combining ensemble approaches, optimization algorithms, and transfer learning, our methodology efficiently addresses typical problems, including underfitting, overfitting, and model bias. This study provides a strong tool for skin cancer diagnosis and a precedent for future research in medical imaging, highlighting the possibility of incorporating evolutionary algorithms and meta-learning to enhance predictive performance.
