New method uses diffusion models for functional data augmentation

Researchers have developed a new method for augmenting functional data using a class-conditional functional diffusion generator. This approach provides theoretical guarantees in Wasserstein-1 distance, bounding the risk of training on synthetic data. The study demonstrates that this augmentation can improve classification and regression tasks, particularly in cases of class imbalance where directing synthetic curves to minority classes yields the largest gains. AI
