Conditional Data Synthesis Augmentation (CoDSA) is a framework that uses generative models to synthesize diverse and well-distributed data for improving machine learning and statistical analysis.
CoDSA focuses on addressing data limitations and biases by generating synthetic samples that capture the conditional distributions of the original data, particularly in under-sampled or high-interest regions.
CoDSA leverages transfer learning to enhance the realism of synthetic data and increase sample density in sparse areas, preserving inter-modal relationships and improving domain adaptation and generalization of models.
Experiments indicate that CoDSA consistently outperforms non-adaptive augmentation strategies and state-of-the-art baselines in both supervised and unsupervised settings.
