Mixup Augmentation

Mixup augmentation is a data augmentation technique that generates synthetic training examples by linearly interpolating pairs of data points and their labels. Current research focuses on improving mixup's effectiveness through adaptive perturbation strategies, generating multiple interpolations, and integrating it with other techniques like self-paced learning, contrastive learning, and multiple instance learning, particularly for challenging tasks such as semi-supervised learning, imbalanced datasets, and low-resource scenarios. These advancements aim to enhance model generalization, robustness, and calibration, leading to improved performance in various applications, including medical image analysis, speech recognition, and object detection. The impact of mixup is significant because it offers a simple yet effective way to improve model training with minimal computational overhead.
