The paper provides theoretical convergence guarantees for ODE-based Flow Matching models, demonstrating that samples generated in a latent space by transformer networks with a pre-trained autoencoder converge to the target data distribution in Wasserstein-2 distance, while accounting for potential domain shift.
Key insights
- Transformer networks, when appropriately constrained, can effectively approximate smooth functions while maintaining a Lipschitz constant independent of the approximation error, which is crucial for ODE stability.
- The overall performance of the latent space generative model is directly influenced by the reconstruction quality of the pre-trained autoencoder and the domain shift between the pre-training and target datasets.
- A rigorous end-to-end error analysis can bridge the gap between empirical effectiveness and formal mathematical guarantees for complex generative model architectures.
