Researchers have developed a novel method called PaCoDi (Parallel Complex Diffusion) to improve the generation of time series data using diffusion models. This approach operates in the spectral domain, decomposing temporal dependencies to simplify the diffusion process and overcome the "curse of entanglement." PaCoDi utilizes parallel real-valued estimators for complex-valued dynamics, theoretically proving its statistical orthogonality and extending to continuous-time SDEs. Experiments show PaCoDi achieves superior generative quality and computational efficiency compared to existing methods. AI
