This paper introduces DT-GAN, a novel GAN architecture that addresses the theoretical fragility and instability of traditional GANs. By using linear operators with explicit constraints, DT-GAN offers improved interpretability, stability, and provable correctness, particularly for data with sparse synthesis structure. The work provides a strong theoretical foundation and experimental validation, showcasing a promising alternative to neural GANs in specific scenarios.
Key Takeaways
- •DT-GAN is a model-based adversarial framework using a sparse synthesis dictionary and an analysis transform.
- •It offers improved theoretical properties compared to neural GANs, including well-posedness and stability.
- •DT-GAN is particularly suitable for data with sparse synthesis structure.
- •Experiments validate the theoretical predictions and demonstrate stable behavior compared to standard GANs.
