Searching for Robust Augmentations to Improve Out-of-Domain Generalization in Dermoscopic Skin Cancer Classification
TL;DR
Robust data augmentations significantly enhance out-of-domain generalization in dermoscopic skin cancer classification. A mix policy using photometric transformations yielded the highest performance improvements.
✦ Why It Matters
Implement robust data augmentation strategies to enhance model performance on diverse datasets today.
Key Takeaways
- Explore mix policies for data augmentation in skin cancer classification.
- Utilize photometric transformations to improve model robustness.
- Evaluate model performance using ROC-AUC metrics.
- Test classifiers on diverse datasets to ensure generalization.
How It Works
The study employs a mix policy that combines various augmentation techniques, particularly focusing on photometric transformations, which adjust the color and lighting of images. This approach helps the model learn to recognize skin lesions under different conditions, thereby improving its ability to generalize to unseen data.
